Letter from the Editor

t has been exactly twelve months since the first ProAgri BNZ saw the light in September of 2019. We are officially one year old. The magazine is still in its infancy compared to ProAgri Media that celebrated its 25th year in August this year. What a year it has been! The agricultural industry of Southern Africa certainly has seen its share of hardships in the past year. From the outbreak of foot and mouth disease in 2019 to the swarms of locusts that are currently threatening farmers’ crops, to say nothing about the economic restrictions of the COVID-19 pandemic that are still dragging on. In spite of these adversities, ProAgri BNZ has shown exceptional growth. We have evolved to incorporate printed, social, and digital media, and have reached more than 1,8 million people in the region through our various platforms every month. This is testa-

ment not only to the work ethics and dedication of the team that creates ProAgri BNZ every month, but also to the farmers of Southern Africa. We are constantly reminded of the resilience of our farming communities by the e-mails and comments that we receive from our readers. We are looking forward to more growth during the next year. Apart from our own strategies that will see ProAgri expanding our readership in the SADC region, we also see economies beginning to regain some traction as we emerge from lockdown. Soon the borders will be operating at normal capacity again, which will go a long way to stimulate regional trade. We at ProAgri appreciate all the readers that have reached out to us to gain more information, or to share their local news. We use the feedback from our readers to stay up to date with what the farmers are doing, and what information they need to farm better and smarter. Remember that you can also gain access to our information through our various online and digital platforms.

Buy a LEMKEN planter for peace of mind, reliability and after sales service by Benine Ackermann

Hannes Bruwer from Genade-boerdery, Hopetown, planting wheat with his LEMKEN Solitaire 9 in combination with his Rubin 10 cultivator.

or the best technology, uniform plant depth, and precise seed placement, the LEMKEN planter is the ultimate answer. Furthermore, LEMKEN implements are the strongest in the country. The LEMKEN Soltair 9 is the best fine seed planter for wheat, barley, alfalfa, feed sorghum, beans and teff. The Solitair 9 can be used on its own or mounted on a Rubin, Heliodor, or Kristall seedbed cultivator to prepare perfect seedbeds for seeds to develop into healthy plants. The planter is 6 metres wide, carries 1,8 tonnes of wheat seed, and plants in rows of 150 mm. A tractor of 200 to 220 kW is needed for the combination of the planter and a LEMKEN compact disc harrow.

LEMKEN’s implements is that they can either be used separately or in combination.” Gerhard Bruwer “LEMKEN’s planter combination is a major benefit, as it reduces the need for other cultivations and save on costs. The seedbed and planting mechanism are ideal to suit any farmer’s needs. “It can plant approximately 30

hectares before being replenished, and plants between 5 and 15 km/h, which means you can easily plant 50 hectares per day. “The Solitair 9’s electronic seedmetering adapts automatically to the tractor speed.” Vicky Bruwer “LEMKEN helps the farmer to save on cultivations with their multi-purpose

Northern Cape farmers explain why they are so impressed with the Solitair 9 planter: The Bruwer family of Genadeboerdery, Hopetown and Douglas Hannes Bruwer: “The planter is very versatile. It plants from canola at 3 kg/ ha to wheat at 200 kg/ha. The small row interspace is most welcome for weed control, as the plants quickly form a canopy. “We never had any problems with LEMKEN’s after sales service. They establish relationships with their clients. “I like the combination of the Solitair and Rubin 10 with its larger discs. The Rubin 10 smooths out rough and uneven soil to form a perfect seedbed. “Another important benefit of 2

implements. The soil to seed contact is very good, and the rows are narrower than those of a conventional planter. “Every morning we check the whole machine and apply lubrication to all the necessary parts. This helps to prevent breakages and unnecessary wear. We also take care to stock enough basic parts to make sure that the planter will not be idle in busy times. Hein Mülke from Zoutpansdrift, Douglas “Look, the German’s do not manufacture junk. LEMKEN definitely offers equipment of the highest quality. The availability of parts is no problem because parts and service are available wherever LEMKEN implements are sold. Their service is exceptionally good. Wrench Cilliers, Foreman of Depla-boerdery, Douglas “Any implement that lasts on this farm must be good, for here we work hard and long hours. LEMKEN’s equipment perfectly suits our whole setup. The Solitair 9 planter is an accurate and first-class planter.”

Kerneels Greyling (Junior) from Frankdale, Prieska Two of the first farmers between Prieska and Douglas to acquire a Solitair planter were Kerneels Greyling and his father. “I am most impressed with the planter combination, and it keeps me busy because all my neighbours ask me to help them with the Solitair planter. “The reason for their requests is the Solitair’s seedbed preparation and accurate seed placement. The calibration is very precise and very user friendly. “LEMKEN’s people render superb service and they are definitely moving forward with the technology.”

Kerneels Greyling

Org Teesen from Otterfontein, Koster “Pastures planted with LEMKEN develop uniformly, leading to a far better harvest. I have not used any other planter in the past five years. When a farmer uses the Heliodor in combination with the planter, he saves on fuel and needs fewer tractors. The seed is gently placed on a predetermined, adjustable depth – not simply strewn out and covered. The uniform emergence also helps a lot and makes cultivation after emergence easier. “In the morning, I fill in the hopper with enough seed for the day, and no replenishment is necessary during the day. “It is easy and simple to calibrate the planter, and it takes only ten minutes. This is how it works: You look at the weighing chart on the side of the planter and choose your type of seed from one of the five settings. Everything works electronically. You use the electronic scale to weigh the quantity of seed you wish to place per hectare and read it in on the screen. Then the planter calculates the hectares and weigh it against the quantity of seed by itself. Never was I more than 12 kg per 50 hectares out. You can calibrate your planter precisely.” SW Hugo from Lakewarden, Bloemhof “The technology is of high quality and it is a good, sturdily constructed product. LEMKEN’s service is in a class of its own. It is definitely worth your while to acquire such a planter.

How to handle your beef cattle Part 11:

Building water troughs, fencing, gates, pens and roads The devil is in the detail and keeping this in mind is especially important when designing your feedlot. You can save yourself a lot of trouble, time and money if you spend a good part of your project on planning the nitty-gritty parts of your feedlot. Water troughs Water troughs are placed approximately two-thirds of the camp length from the feeding troughs and on the border between two pens, so that both pens can be served by one trough. Water troughs must be cleaned regularly. For this purpose, a 50 mm tap can be provided at the lowest end for drainage as shown in Figure 1. The water for washing the trough causes muddy conditions in the pens. Provide the pen with a concrete trench to drain the water from the pen, or use PVC pipe or quick-couple pipe when troughs are being drained. Provide a concrete slab (75 to 100 mm thick) around the trough, extending two metres on the long sides and 0,5 m on the short sides. The purpose of the concrete slab is to prevent trampling around the troughs. The ball valve must be well protected against possible damage by the cattle. Figure 2 shows a typical plan of a water trough.

Figure 1: Water trough with drainage. 6

Figure 2: Water trough. Fences Feedlot fences differ from the usual camp fences. In feedlots there is a higher concentration of cattle and the fences must therefore be sturdier. Fences in these pens are 1,5 m high and consist of five cross wires. Barbed wire injures the cattle and ordinary wire is not strong enough. Steel cables instead of cross wires are recommended. Another possibility is to make a cable from galvanised wire and steel wire. One 4 mm galvanised wire is used with two 2,24 mm high tensile steel wires. The length of the wire is slightly longer than the distance it has to span. The loose ends of the wire are tied to the power take-off shaft of a tractor by pulling the ends through the hole on the power take-off shaft. The other ends are tied in position to a corner post. The wires are tightened slightly. Ensure that the tractorâ&#x20AC;&#x2122;s brakes are disengaged and that the gears are in neutral. At idling speed, get the power take-off shaft in operation for 2 to 3 seconds, to wind up the cable slightly. This cable can now be drawn tight and used as fencing cable. Wood or steel can be used for the standard poles and droppers. Standard poles must be placed three metres apart in the earth and one dropper can be

placed between them. If wood is used for standard poles, the diameter must be 100/125 mm, while 32/50 mm droppers can be used. If steel is used for standard poles, pipes with a 100 mm diameter, 100 mm IPI-I-beams, or railway sleepers can be used, depending on the cost. If sturdier poles are used, such as metal train rails, the standards can be placed 4,6 m apart, with two droppers between them. All poles must be planted firmly into concrete. Figure 3 shows the construction of a typical fence. The top cross wire in the fence can also be replaced with a pipe to ensure sturdiness of the fence, as shown in Figure 4. If round pipe standards are used, the bottom part must protrude from under the concrete into the soil to ensure drainage and prevent rust. Poles must be sealed at the top to prevent rainwater from collecting inside the pole and causing erosion. The concrete anchor blocks should be built slightly higher than the soil surface and tapered away from the pole. This is to protect the poles from erosion because of the high urine concentration and water collection around the pole. At gates and at the end of the fence, the standards must always be anchored. Fences must be maintained regularly to ensure long life. If wooden poles are

If the set-up justifies it, gravel roads, thoroughly compacted by rollers, can be built. An investment in a road is an investment in success.

Steel poles must be treated with an anti-corrosive substance, if it has not been done by the manufacturers. Treat the poles before planting, it will be easier and will ensure that it is done thoroughly. Gates If the cattle walkway is used as an access to the pens at the lower side of the pens, the walkway must be wide enough to allow cleaning machinery to turn easily into the pens. Alternatively the gates must be adapted, as shown in Figure 5, or larger gates must be used. It is, however, advisable to rather use the gates at the feeding trough. Standard 3,5 m wide gates are not strong enough to inhibit cattle effectively and must be strengthened, or heavy duty gates must be used. The locking mechanism of the gate must be such that it can be easily opened and closed, but not by the cattle.

Figure 5: Fence adaptation for entrance to pens.

Figure 7: A field pen where cattle can be handled with ease.

Figure 6: Drainage of pens. Preparation of pens Before building work can begin, the site must be cleaned and graded according to slope. It is worth doing a complete survey and grading the inclines correctly from the onset. Roof runoff water or any other water from the site around and above the pens must be drained separately from the pen run-off. Make special drainage canals so that the water does not run through the pens. Prevent the water from running from one pen to another. Figure 6 shows a practical solution for drainage of pens. Pen surfaces must be finished neatly, so that rain water cannot dam up. The pen surface must preferably be compacted with a roller. In high rainfall areas hills are often constructed in pens. The hills provide a drier place to lie down. The hills must however be constructed in the centre and not at the sides of the pens. This will slow down wear and tear on fences because the poles will not be standing in the mud. Pen maintenance must be done regularly during production. By constructing a sufficient number of pens, pens will be able to rest for a week or two. Roads Roads in and around the feedlot must be of high quality. They are indeed the backbone of the enterprise. These roads carry very heavy traffic as cattle, feed wagons and cleaning wagons move over them daily. If the roads are in a poor condition, it will slow down the whole growing process of the cattle.

Groundwater quality is changing across the country, shortening the lifespan of center pivots by corroding pipelines. Water containing chlorides and sulfates can corrode galvanized pipe, and water with high or low pH levels can decrease pipe lifespan even more. In addition, many growers are using wastewater and process water for irrigating, and applying crop protection chemicals or soil amendment products through their pivots.

Spray to protect your crops Part 11:

The calibration procedure

Compiled by J Fuls (Pr Eng)

Last month we discussed what you should do to prepare for calibration. This month we look at the actual calibration process and the steps you must take to ensure that your sprayer delivers the correct quantity of chemicals.

n the label of the chemicals one finds how much chemicals must be applied onto each hectare of land. Because the chemicals in the container are very strong and concentrated, we have to mix it with water to spray with the sprayer. If we now know how many tanks will be used to cover one hectare with the sprayer, we can calculate how much chemicals should be added to a full tank of water every time we refill the sprayer tank. To calculate this is very simple:

The formula is: (Litres per hectare needed) ÷ (Number of tanks per hectare) = Litres per tank 6 ÷ 4 = 1,5 ℓ/tank Now here is one way to determine how many times the tank will have to be filled to spray one hectare: d. Stand the tank on a level spot and fill the tank with clean water up to a clear mark inside the tank.

If the label says you should apply six litres of chemicals per hectare:

a. Flush the tank with clean water and make sure it is clean.

e. Spray up and down this 50-metre strip in the field, to cover a total of 100 metres.

And if we empty four knapsack sprayers over one hectare (Let us suppose the field is one hectare big):

b. Fill the tank with clean water and practice in the field. Make sure everything is working well.

50 m Then we must add one and a half litres of chemicals to a full tank, every time we refill the sprayer:

c. Mark off a length of 50 metres in the field, using your measuring wheel or tape measure.

ProAgri Botswana / Namibia / Zimbabwe 12

f. Stand the sprayer on the same spot as previously, and re-fill it to the same mark, using the measuring jug or measuring bottles. Write down how much water had to be added to refill to the mark. Suppose you had to add 1,25 litres of water to re-fill the tank. Now for every 100 metres you walk, the sprayer will deliver 1,25 litres of water. 9

ProAgri BNZ 12

g. Calculate the distance you will have to walk until the tank is empty: On the side of your sprayer tank, you will find marks to indicate how much water is in the tank. Read next to the full mark how much water it can take. Suppose this is a 16 litre sprayer. The distance you will walk is 16 ÷ 1,25 x 100 = 1 280 metres. This means that the tank will be empty after having sprayed 1 280 metres.

For each one hectare sprayed, the total distance walked will then be 2 x 100 x 111 = 22 200 metres.

•

i. Calculate the number of refillings needed for each one hectare sprayed: If a full tank lasts for 1 280 metres, and the total distance walked while spraying one hectare is 22 200 metres, the tank will have to be refilled 22 200 ÷ 1 280 = 17,3 times. (Do not worry about the decimal ,3. It simply means we will need a little more than 17 re-fillings for each hectare sprayed.)

The quantity of chemicals to mix into each tank refill is: 5 x 6 x 0,9 x 16 ÷ 1,25 = 346 millilitres.

j. Calculate the amount of chemicals needed for each refilling: Remember the formula at the start of this section: (Litres per hectare needed) ÷ (Number of tanks per hectare) = Litres per tank If the litres per hectare needed is 6, and the number of tanks per hectare is 17, we can calculate the quantity of chemicals to add to each tank refilling to be: 6 ÷ 17,3 = 0,346 litres, or 346 millilitres. (1 000 millilitres make up one litre.) One can combine all the calculations into one formula. Just remember the following: • We do the test spray over a total distance of 100 metres. • We measure the test refilling in litres, not millilitres. • When spraying, we walk two times over each row. • The chemicals to be applied per hectare is specified in litres per hectare • The row width is to be measured in metres • The tank volume must be given in litres

h. Calculate the total distance walked when spraying an area of one hectare. Remember that one hectare is a land size of 100 metres long and 100 metres wide. The row spacing you plant may be 0,9 metre. The number of rows over one hectare will then be 100 ÷ 0,9 = 111 rows.

Over the 100-metre test, 1,25 litres were needed to refill the tank to the same mark

The formula now looks like this: The quantity of chemicals to add to each tank re-fill is 5 x (chemicals per hectare) x (row width) x (tank volume) ÷ test volume = Millilitres

When mixing in the chemicals, use the 500 ml measuring bottle, fill it to just below the 375 ml mark and add this to the spray tank. Put on your face mask to protect your eyes, for the chemicals may splash. Just remember to rinse the measuring bottle three times into the sprayer tank before putting it away in a safe place, out of reach of children.

In our example above, we had: • Chemicals per hectare specified on the chemical container: 6 litres/ hectare • Row width: 0,9 metres • Sprayer tank volume: 16 litres

Now remember that we decided to go up and down on one row when spraying to get the required overlap for good coverage. ProAgri Botswana / Namibia / Zimbabwe 12

Pineapples thrive under Agrico pivots A

project away from your home country may sometimes be a risk, but presently, Agrico is making a mark on a pineapple farm in Swaziland. The Rhodes Group, well known for their canning factories, last year embarked on pineapple production on the Norsa farm near Siphofaneni. “Agrico already had pivots on the farm for a previous cassava project, and that is how we came to know them,” says Genesi Langwenya, the Rhodes Group’s General Manager for pineapple farms. “We decided to continue using Agrico’s services. The last two years, we have been planting pineapples and Agrico erected more pivots as the farm expanded. The farm already irrigates 1 100 ha with 25 Agrico pivots,” he said. “The reason why we prefer pivot irrigation is that pivots are far more effective than water cannons. Pivots demand far less labour than water cannons and use water more effectively. Moreover, the farm is very hilly, and Agrico’s pivots handle slopes very well,” Genesi said. Although the Usutu river runs along the farm’s border, they are subjected to restricted water allocations, but with Agrico’s pivots, they easily stay within their quota. Pineapples do not require that much water (70 to 80 mm/month), but it is extremely important that the water is delivered at regular intervals and evenly (with a high degree of uniformity). This is where pivots outperform any other irrigation system. You can easily change the water application according to your crop’s needs and the uniformity of application is exceedingly high. Agrico also expanded the pump stations in the river and at the storage dams supplying the various pivots. They

Accurate scheduling For accurate irrigation scheduling, they now placed probes under each pivot. These probes can be integrated with the web control system to make sure that exactly the desired amount of water is applied. Although the water from the river is clean enough for pivot irrigation, blockages of the sprinklers may sometimes still occur, but they are easy to remove by simply opening and cleaning them. With micro or drip irrigation, proper filtration would have been needed with the added disadvantages of losing pressure,

wasting water with backwashing and increased danger of blockages. Agrico high clearance pivots are used. Should the plans change, they are already suitable for the production of taller crops such as sugarcane. According to Genesi, Agrico’s service is superb: “When you embark on a new project, you will always experience teething problems, but with Agrico you can sit around a table and quickly solve matters. We can discuss our plans for the future with Agrico’s people and bank on their understanding. That is why we are fully satisfied with their expertise, service, and support,” he said.

Talbert is the farmer’s irrigation ally A

A strong centre A lot of attention is given to the strength and stability of the centre tower, as this is the heartbeat of any centre pivot. The weather-proof control panel is designed to control the system safely and efficiently. Built-in sensors switch the pivot off if the water pressure drops too low. Quality approved industrial gearboxes drive the pivots, and if needed, gearbox spares are readily available nation-wide.

centre pivot is supposed to ease the workload of a farmer and not add to the problems that farmers need to deal with every day. This means that the provider is as important as the centre pivot itself. Talbert centre pivots were developed 28 years ago on the farm, and were designed and manufactured with Southern African circumstances in mind. Here are a few reasons why you should choose Talbert pivots: Special design In sandy soil or heavy clays, from giant maize circles to a small patch of lucerne, Talbert understands the farmer’s needs and makes sure that his centre pivot will suit his unique requirements. The ultimate goal is increasing production and profits. The Talbert irrigation system is designed to be userfriendly and durable. Only the best materials Talbert incorporates the latest technology and highest quality materials to ensure the efficiency of their centre pivots. All steel components are galvanised and strongly adhere to SABS 763 standards. The pipe walls are 3,5 mm thick and the heavy-duty A-frame structure ensures structural integrity even in extreme conditions. Talbert manufactures each centre pivot in their own South African

factory. This ensures the highest quality standards and the prompt availability of parts and accessories. No blockages A valuable standard accessory on all Talbert pivots is the sand catcher. This ensures that the sprayers do not clog and also facilitates the cleaning process. Irrigate at night A bright light on the final tower enables the farmer to irrigate at night and therefore limit the effect of evaporation. Tower couplings The unique tower couplings are made of a high-quality rubber and remain completely covered to protect them from the harmful UV-rays.

Quick service Talbert irrigation systems are supported by a wide dealership network in order to ensure a quick response time. “Just as the centre pivots keep working on the farm, we keep working with the farmer. Should a centre pivot stop for maintenance or repairs, we always get it working again as soon as possible,” says Jannie Steyl, founder of Talbert.

G r o u n d w a t e r (1 ) Soil is the most fundamental resource for the farmer, without which food and natural fibre cannot be produced. This article forms part of a series to highlight this resource.

he interaction of water in soil and plants is of exceptional importance for the crop farmer, because soil is the medium that captures and retains water for plants and makes it available again to the plants over time. It also serves as a solvent for plant nutritional substances which then form the soil solution. In the next few articles in this series, water in the soil will be discussed. The energy state of water is the basis of water movement and retention in soil. In this article capillarity and the energy state of water in soil are discussed. The water molecule The structure of the water molecule is fundamental to its behaviour. The water molecule comprises one oxygen atom (O) and two hydrogen atoms (H) to form the chemical compound H2O. Of great importance is that the two hydrogen atoms are not diametrically opposite each other around the O atom, but both are found on one side, forming an angle of 104,5° (Figure 1). The implication of this is that the water molecule is polarised. It is therefore slightly positive on the side of the two H atoms and slightly negative on the side of the O atom, while the Electropositive

water molecule itself is neutral. This polarity results in water molecules attracting each other electrostatically (cohesion). Amongst other things, cohesion causes surface tension, which is actually a thin dense elastic layer of water molecules (meniscus) on the surface of the water. Furthermore, the polarity property is also responsible for the concave meniscus of the water surface when, for example, it is in a glass tube (adhesion). Surface tension and the meniscus are of major importance in soil, because they result in forces that retain water in the soil and allow it to move. The polarity property also causes ions such as H+, Na+, Mg2+ and Ca2+ to be hydrated with water molecules. It also binds electrostatically with the negative clay surfaces to form a very thin layer of water molecules. Capillary mechanism Capillarity can be demonstrated when the one end of a narrow glass tube (or straw) is placed in a bowl of water and is held upright. Water moves upwards in the tube, contrary to the forces of gravity. The water molecules “creep” via adhesive forces (between the polar water molecule and the side of the glass tube) upwards and pull the next molecules with them using the cohesion forces (between water molecules). This movement continues until the attraction force of the earth (gravitation) on the water in the tube is equal to these forces and the water can no longer move further. The narrower the tube, the greater the curve of the meniscus, the stronger the force and the higher the water can move upwards. Exactly the same happens in the narrow tubes (pores) between soil particles where the water can then move upwards and sideways in the soil (Figure 2). The pores in coarse sand are larger, with the result that the water can

ProAgri Botswana / Namibia / Zimbabwe 12

Martiens du Plessis, Soil Scientist, NWK Limited & Prof Cornie van Huyssteen, Lecturer: Soil Science, University of the Free State move more rapidly, but not very high (about 400 mm). In loam soils the pores are narrower and the water can move upwards as much as 800 mm, although more slowly. In clayey soils the water moves even more slowly and often not high, because clay usually has a strong structure without long continuous capillary tubes. Energy state of water Whenever an object moves from one place to another, work is performed and this requires energy. Water always moves from a higher energy level to a lower level. When the energy level in one place is the same as in another, movement will not take place. A number of factors result in various energy levels in soil. These energy levels provide the forces that allow water to move. Gravity potential Gravity potential refers to forces of gravity which draw the water downwards towards the centre of the earth. Water higher up in the soil is therefore constantly drawn downwards and thus deeper into the soil. Water that is higher in the profile therefore has a higher energy state than water deeper in the profile. Gravity potential therefore causes the water, following rain or irrigation, to drain deeper into the soil. When free water occurs above the reference point, it exercises a downwards and thus positive pressure on the water in the soil. It will therefore cause the energy level of water to increase and it will move more rapidly. The thicker the layer of water, the greater the water potential. Matrix potential Matrix potential is caused by adhesive and cohesive forces as well as menisci. Adhesive forces result in water molecules clinging to the soil particles in a thin dense layer and cohesive forces cause other water molecules 17

Goat production guide part 1:

The business plan by Jaco Cilliers

hen planning to farm with goats, many aspects have to be considered. These considerations include housing, feed, and animal health. These crucial aspects will be discussed in this series in due course. The first step in any successful farming enterprise, is setting up a business plan. This will allow you to work efficiently and goal orientated, and will grant you access to development loans. What is a business plan? A business plan is a document of how a business owner, manager or entrepreneur intends to organise a new business and establish activities for the venture to succeed. Businesses need plans to optimise growth and development according to priorities. A business plan is not only to look for financial assistance or for initiating a business start-up, but it is an evolving working document that should be reviewed regularly and adopted to circumstances as and when the internal and external environments change. To raise funds for a new business venture or to raise additional capital, your document must meet the requirements of a funding institution or sponsor. A good business plan involves research on the external and internal business environment like competitors, suppliers, consumers, et cetera, which can be translated into a detailed action plan showing the areas of competitive advantage and how you will combat problems. You can use the business plan to identify opportunities, analyse the life cycle of the business and each activity in the business, and plan for capital requirements. Common mistakes in the drafting of business plans Cash flow Most prospective entrepreneurs focus mainly on the infrastructure that is required and ignore the cash flow which is critical to the daily operations of the business. Cash flow assists in managing your financial resources, that is debtors and creditors control. Vague business plans Prospective entrepreneurs or writers of business plans often wrongly assume that the reader/funding institution/investor knows what the business venture is all about. Therefore, it is important to provide as much detail 20

as possible and elaborate wherever necessary to clarify the needs of the business. Unrealistic assumptions Almost all writers of business plans assume that the business will succeed, hence they make unrealistic assumptions. It is advisable to benchmark against existing or similar businesses in the industry for acceptable standards. The goals of the business must be realistic and achievable. Rather start small and then expand. Risks Many business plans ignore the risks or do not make provision for the risks. It is critical that the business plan should include all risks and provide information on how some of these risks can be mitigated. Competition Many prospective entrepreneurs fail to incorporate information on competitors, either through their lack of knowledge of them or they are not aware of the significance of competitors to their business. It is, therefore, imperative, as a new or existing business, that you are aware of the competition and that you accentuate your competitive advantages in your business plan. Suppliers Suppliers play a critical role in your business. It is important to know who and where your suppliers are as they contribute to the effective and efficient running of your business. Inconsistent and lacking inputs from suppliers will impact negatively on production and could result in non-delivery of products to the market. Hence building and strengthening relationships with your suppliers contribute to the long-term sustainability of your business. Recommended production systems size The size of your goat farming business will depend on a number of variables, the amounts of capital available being the main determining factor. You need to keep the carrying capacity of the natural vegetation in mind as well. The carrying capacity differs greatly between the climatic regions. It is important that you do not exceed the carrying capacity of the land that is available to you. This will lead to increased feeding costs, and it is very expensive

to regenerate overgrazed pastures. Keeping this in mind, there is also a minimum number of goats that you can keep in order for the business to remain viable. In a region where there are a lot of competitors, a farmer may need to lower his profit margins to stay within the competitive price range. Lower profit margins necessitate higher volumes for the business to remain profitable. Farmers need to attain the correct balance between the minimum number of goats that they can keep while remaining profitable, and the maximum number of goats that they can afford to keep. The points below refer to aspects that prospective farmers need to keep in mind with specific reference to goat farming. Access to land Having access to adequate grazing is crucial to keep feeding costs low. Goats are also notorious for breaking through fences, so robust barriers need to be in place in order to keep the goats in and predators out. Apart from the threat of

ProAgri BNZ 12

predators, goats are also easy targets for stock theft. Having land that has water readily available is a great benefit as it will eliminate the costs of boreholes or water pipelines. Housing and other equipment needs Good quality housing is expensive, but in the long run it saves money. Goats can be kept out of the elements which will lead to a healthier herd. Secure housing will also help to protect your herd from predators and thieves. The housing must have a dry floor and proper ventilation. Feed and water troughs are essential equipment that you will need to budget for. Apart from this, you will also need handling facilities such as holding pens, a crush, and a loading ramp to ease working with the animals. Breeding stock The goal is to buy initial breeding stock that can be mated to produce more goats. Buying from a reputable breeder might be more expensive, but it ensures good genetic material that can result in better returns on initial investment in the long run. It is recommended to consult with a local expert to get the best value for money when buying animals that you intend to breed. You will also need to consider which goat breed will best suit the purpose that you want to keep them for. Indigenous goats and Boer goats are normally kept for meat production while Angora goats are used for mohair production. It is also important to ensure that the goat breed of your choice is well suited to the environmental conditions. The goat breed, availability of feed, adequate housing and access to land are all important factors to consider when starting a goat farming business.

Feeding costs Even if you have access to enough land that can provide the goats with adequate grazing, you will still need to buy feed to supplement their nutritional needs and ensure good growth and weight gain. This can be expensive. Farmers generally tend to calculate how much feed they will need in a production cycle and then buy in bulk to cut costs and ensure regular availability. Once you have done the research and compiled a strategy that will enable you to start and successfully grow a goat farming business, you can move on to the implementation of your ideas. For more information, contact your local agricultural offices or ask for advice from experts in the industry in your area.

Irrigation made easy part 5:

The labour cost of irrigation and system maintenance A

n important part of irrigation planning and operation is understanding how hard a person must work to apply the required amount of water to the crop in the field. On large commercial farms, a single labourer could be used to control an irrigation area of up to 40 hectares. Labour intensive systems could, however, require two to three labourers per hectare to properly irrigate the field. Labour usage is important regardless of the size or type of irrigation system used. A commercial farmer must understand the cost implications of maintaining a labour team merely to operate the irrigation system. For a small-scale farmer who only irrigates a small area, it is equally important to understand how much time will be spent each day to operate the irrigation system and if there is enough time left to schedule other important activities such as weeding, spraying for pests, harvesting and marketing. A farmer who, for example, grows kiwi fruit on a vine and harvests at regular intervals throughout the fruiting season will still need to continue irrigating, weeding and performing other normal farming operations throughout the harvest period. Therefore, a farmer must know how much time is needed to perform each task and plan a schedule for daily activities. For a large-scale or commercial farmer, labour usage would typically be indicated in terms of the number of people needed to irrigate a 10 hectare block, or the entire system. This will impact directly on the labour component of running costs for the system 22

and on the availability of labour to perform other tasks. Labour requirements have a different implication for the market gardener or small-scale farmer. It is important to schedule all tasks and activities for the day. Labour requirements will more typically be expressed in terms of the amount of time normally needed for one person to irrigate one hectare when crop water demands are at a peak. This, in turn defines the time available for other tasks. System maintenance Every irrigation system needs regular maintenance. How complex or difficult maintenance tasks are likely to be, the amount of labour (with different levels of skill) that is needed to perform these tasks, the cost of equipment and spare parts, the frequency of maintenance operations and the availability of

Figure 3: Scheduling goes hand in hand with effective labour management. technical support can each make a big difference to the viability of an irrigation system. Maintenance is important. Poor maintenance will allow an irrigation system to degrade. Water distribution

and irrigation efficiency will suffer. A typical maintenance task is the regular checking of sprinkler nozzles for wear. If a nozzle is worn, more water will escape from the nozzle at normal operating pressures. The distribution pattern of water around the sprinkler will change. Less water will be available to other sprinklers in the system. The pump will not work as efficiently. Energy costs will increase, irrigation efficiency will drop and crop production will decrease. Regularly check sprinkler

nozzles for wear and replace worn nozzles with new nozzles of the correct size and type. Each type of irrigation system will naturally have a list of maintenance operations that must be carried out on a routine basis to ensure that the system continues to function correctly. It is important that each irrigation farmer should have an operations manual for his system that details maintenance tasks, and a toolbox that contains all the tools and equipment needed to perform routine maintenance tasks. A farmer should also maintain a contact list of people who can be approached for advice or assistance with specific problems that may be encountered when operating the system.

Next month we shall look at scheduling water use. This series is published with acknowledgement to the ARC Agricultural Engineering for the use of their manuals. Visit www.arc.agric.za for more information.

Sprinkler nozzles are a sensitive part of your system and need regular check-ups.

Mechanise with versatile implements that maximise output and optimise your soil preparation P rofits rise when plants are provided with perfect soil conditions in which to thrive. Therefore, proper soil preparation is an important part of crop farming. The process of preparing the soil and establishing crops is highly complex and unique to each farm. It is based on a wide range of variables, including the crop, the climate, humidity, other growing conditions, and the incorporation of many years of experience of what has been shown to work, or not work, for a particular farm. Soil preparation involves loosening and processing of the soil to ultimately make the land ready for the introduction of seed into the soil, and it involves a range of processes to reduce soil compaction, increase aeration and promote development of the root systems of plants, reducing weed growth, fertiliser incorporation, crop residues

management, and finally the seedbed preparation for planting. Input costs are constantly rising, therefore selecting the right preparation techniques and equipment to attain the intended outcome, is critical. Versatility is one of the features farmers expect from soil tillage equipment as it simply makes sense to acquire an implement that can be used for various requirements. The Amazone range of soil cultivation implements offers the farmer everything from entry level solutions, through to the most advanced mechanised agricultural technology to suit every farm’s needs and budget. Amazone implements are distributed in South Africa by Falcon Agricultural Equipment, and the cultivation range available includes compact disc harrows, cultivators, and rotary harrows. The Amazone Catros, a compact disc harrow, is ideal for quick, shallow, and intensive stubble-mixing work and operates without plugging, even with high quantities of surface straw. It is used mainly to incorporate maize stover and wheat stubble, to loosen up grassland or uncultivated land, and to incorporate organic manure. It is available in working widths of 2,5 m to 12 m and can work between 50 mm and 150 mm deep. The mulch cultivator range includes the Amazone Cenius-2TX trailed mulch cultivator and the Ceus-2TX tine & disc combination cultivator. The Cenius2TX can be used for jobs from shallow stubble work to deep topsoil loosening

They are running their whole factory, including the heavy steel cutting equipment, from their own solar electricity plant. In the spirit and fashion of a true South African farmer, Willie Jones, the owner and founder, is looking far beyond the borders of South Africa to expand his business. Today he has lined up satisfied clients in Zambia, Zimbabwe, Botswana, Angola, Malawi, Lesotho, Australia, Madagascar, and Mauritius. The first shipment of equipment to the US is also in the pipeline. Jones Masjiene manufactures 120 different types of grain and feed processing machines, including hammer mills, conveyors, lick-block presses, and pellet machines, but they are most famous for their flat die pelleting machines. Compacting feed Pelleted feed offers huge advantages for livestock farmers. It reduces the volume

and storage area, eliminates dust, reduces wastage, prevents animals from segregating feed, improves palatability and prevents infestations by insects. 21 years ago, Jones Masjiene built their first 303 round die pelleting machine and installed it with their first complete feed and pelleting plant on the farm of George Ramasoka from Ramotswa in Botswana. It was driven with a 37-kW motor and used a 4,5-mm die. This machine is still producing between 1,8 and 2,1 tonnes of chicken pellets per hour. Profeeds in Harare in Zimbabwe is also still using a Jones Masjiene pelleting plant with four machines, installed 17 years ago, and all of them are working 24 hours a day, six days a week. Jones Masjiene caters for many more industries and their pelleting dies are available in 3, 4,5, 6, 10 and 16 mm sizes. They supply a range of machines driven by 11 to 45 kW motors, but since the pressure in a pelleting machine gets awfully high with increments in size, Willie prefers to reduce the risk and rather offer two smaller machines instead of a big one. This holds other benefits, such as a reduction in collective down time. Another reason why the pelleting machines from Jones Masjiene are towering above the rest, is that they can handle large chunks of roughage coming out of

A Jones Masjiene feed pelleting machine is a must-have for a serious self-mixing livestock farmer.

A diesel-propelled pelleting machine opens new solutions for farmers who struggle with a stable electricity supply. a normal feed cutter/mixer. You do not need to send the roughage through a hammer mill before pelletising, thereby eliminating the cost and effort of one step, and preventing the loss of nutrients blowing away on dust particles. The higher the accuracy and more advanced the technology of the manufacturing equipment, the faster the manufacturing processes, and the better the machines will be. Jones Masjiene uses the best the market can offer to turn steel into feed plants. They employ a Hypertherm high definition plasma cutter that easily cuts through 50 mm steel plate; a Bystronic fibre laser, Panasonic CO2 welders, and even a Panasonic robot welder. Their milling machines, lathes and bending machines are also on the leading edge. Another exciting Jones Masjiene design is a diesel-driven pelleting machine. This is especially popular with farmers in the bone-dry regions of Namibia and Botswana, who started highly successful â&#x20AC;&#x153;boskosâ&#x20AC;? production with the invasive thorn bushes that invade their grasslands. They can now move their pelletisers to the most remote areas on their vast farms and go home with nicely compacted feed in bags. The cherry on top is the space made available for their pastures to recover once the invader bushes have been utilised. Jones Masjiene is a phone call or e-mail away.

Poultry production guide Part 5: by Jaco Cilliers

Process your poultry to boost your profit A

farm is above all a business and should therefore be operated on sound business principles to be successful. In order to expand your poultry business to become a real poultry producer, you will need to focus on poultry processing. Processing, when done correctly, will enable you to market your product to an entirely new market and unlock potential income. In order to produce profitable poultry, the farmer should ensure that: • everything is done in strict hygienic conditions; • quality and appearance remain consistent; • prices are affordable; • the product is produced with a realistic expiry date. Small-scale farmers can also capitalise on the opportunity to expand their

chicken farms into a poultry producing enterprises. However, certain aspects need to be kept in mind when planning a poultry processing plant. Type of poultry Poultry means more than chickens. The information provided is focussed on broilers, chicken, turkey, and geese. Other types of poultry have different requirements. Poultry handling before slaughter Ensure that feeding stops at least four hours before the poultry arrive at the abattoir. This will ensure that their stomachs and gizzards are empty, which helps to keep conditions in the abattoir more hygienic. Evisceration This part of the process will depend greatly on the target market. Do the research and make sure that you take

local religion into consideration. You might need to comply to Halaal or Kosher standards in order to sell your product to the community. Packaging Packaging can be a very expensive part of the process, depending on how you wish to present your product. Apart from being visually attractive, packaging needs to be functional. If packaging can keep your product fresh, enable easy storage and transport, and does not increase the price of the product too much, there is no need to buy more expensive packaging. There are three basic types of packaging that can tick all the boxes. • Over-wrapping where the meat is wrapped in a clear layer of plastic. • Bag wrapping where the meat is placed into a bag and sealed. The bag can be branded with your logo and product information. • Vacuum packaging where the meat is placed inside a bag and all the air removed to ensure a longer shelf life. Refrigeration Refrigeration is a key part of this process, and no poultry processing plant can exist without it. Meat will easily spoil in the heat of Southern Africa, therefore the product must be kept cold throughout the whole process. A cold chain needs to be established from start to finish to keep the products fresh and safe for consumption. Distribution After the meat is frozen for the first time it should remain frozen until it is ready to be used by the end consumer. It is vital that refrigerated transport is used to distribute the meat from the processing plant to the retail store or market. Meat that is thawed and refrozen will spoil very easily, which will have dire consequences for the producer.

Processing poultry will increase the profit of your chicken farm by enabling you to access new markets. ProAgri Botswana / Namibia / Zimbabwe 12

Pig production guide Part 5: Breeding practices, sow selection and management by Jenny Turton

he success of a piggery lies in the quality of the breeding programme and breeding practices. Using superior genetics and efficient culling will ensure that your pigs are genetically sound, but also limit the costs of keeping pigs that are not producing optimally. Only the best among the young growing female animals on the farm must be selected and kept for breeding. The following guideline will aid in making your piggery more profitable. Select breeding gilts from sows that produce large litters with above average growth rate, and carcasses with a low fat content. The following characteristics should be considered when selecting gilts: • Strong, straight legs with large, even-sized claws. • Gilts should walk straight and well, and stand up on their claws without collapsing at the pastern joints just above the foot. • A well-formed vulva and six wellshaped, prominent teats on each side of the belly. The teats should start well forward and be spaced evenly to allow adequate suckling space for the piglets. • A well-developed ham, good length with light shoulders and head. Replacement of gilts If replacement gilts are not available when needed or if they do not comply with the requirements, the gilts should be bought. It is advisable to buy them from the same farm where the boars come from, because in this way the previous owner can advise you on the breeding policy for a small pig farm. Gilt management before first service Gilts are usually selected for breeding at five to six months of age. The pigs not selected can then be sold as baconers at a live weight of about 85 to 90 kg. The selected gilts are reared to weigh between 120 and 130 kg at seven and a half to eight months of age when they are ready to be served by a boar for the first time. Gilts have to be in a good condition to produce large litters (8 to 10 or more healthy piglets) and should not be too fat when they are ready for mating. Therefore, they should be fed about 2 kg of meal per day from the time of selection until a boar serves them at the age of eight months. This will also ensure that not too much fat is lost during the suckling period and that

they are in a good condition after weaning their first litters. Culling of sows Culled sows must be removed from the farm and sold as soon as possible. It does not pay to keep culled sows on the farm to gain weight before they are sold. As soon as the sow's udder has returned to normal after weaning, it is wise to send her to the abattoir. A replacement gilt can then be brought into the herd immediately. Reasons for removing sows from the herd are usually not known beforehand. Therefore, replacement gilts should always be available so that the number of breeding sows on the farm always remains the same.

Gilts and sows should be carefully selected to ensure that the best genetic traits are carried over to the next generation. Photo: pixabay.com

Sows have to be removed from the herd and slaughtered for the following reasons:

Reasons for culling

% of sows to be culled

Not pregnant

Failure to conceive at service

Do not come on heat

Abortions

Lameness

Poor performance (small litters, etc.)

Old age

Disease

Lack of milk

Sows that farrow regularly and rear large litters (nine or more piglets) and are free of other problems and diseases should rear five to six or even more litters before they have to be removed from the herd. A sow is usually removed from the herd when her litters start to become smaller (two small litters in succession) or when she does not readily come on heat after weaning.

Saving Namibia’s livestock industry Part 7:

Different rangeland approaches or case studies/best practices

he Namibian livestock industry is in decline. There is a large-scale loss of palatable perennial grasses, widely spread bush encroachment, and Namibia is regarded as a country that will be severely affected by climate change. To counter this trend, the Department of Agriculture, Water and Forestry (MAWF), together with industry partners such as the Namibian Farmers’ Union, initiated and developed an innovative rangeland policy that can add N$4 billion per year to the GDP if fully implemented. This is the last extract from the policy document that can help farmers to survive the next drought. The best practices presented in this section are intended to give an idea of methods available and how they have been applied. Case study 7: Alternative feeds for livestock in communal areas Professor Sikhalazo Dube is the Southern African regional representative of the International Livestock Research Institute. At the National Rangeland Forum in 2018, Prof Dube said: “The lack of market access, prolonged dry seasons, livestock deaths and poor income, are all key challenges that smallholder farmers face, with climate change as an added threat to agricultural productivity. There are, however, solutions for smallholder farmers to break out of poverty.” Prof Dube, who worked in the northern regions of Namibia, shared his experiences of crop and livestock farming in Zimbabwe, Swaziland, Malawi and Mozambique. He indicated that four of the five highest-value global agricultural commodities (milk, rice, pigs, cattle, and chicken) are from livestock.

He emphasised the importance of agriculture and added that 4 billion people who live on less than US$10 a day (primarily in developing countries) represent a food market of about $2,9 trillion per year, with an asset value of $1,4 trillion that employs at least 1,3 billion people. There is also massive potential for growth, with expected annual meat consumption increasing from 258 million tonnes in 1997 to 460 million tonnes in 2050. The livestock sector can provide food and nutritional security; power economic development; improve human health; and enhance the environment. Prof Dube warns, however, that the livestock sector must be developed equitably, while mitigating possible health and critical environmental issues. Feed options for cattle “Cattle depend on natural pasture as a main source of feed, but the protein content of grass declines in the dry season. To boost the protein intake of livestock, it is a good idea in certain parts of the country to supplement their feed with forage legumes and crop residues such as groundnut, maize stover, and mucuna (velvet bean) hay reserved from the farmers’ previous harvests.” Prof Dube conducted a feed ration experiment for 56 days with maize stover offered ad libitum in various ratios with crushed maize, soya bean meal, soya bean residue, mucuna hay, mucuna seed, lablab hay, cowpea shells, groundnut residue, poultry litter, beef concentrate, minerals and vitamins. The results were that the body weight of cattle fed on rations based on lablab/cowpea, mucuna and groundnut stover were significantly higher than that of commercial feeds or grassfed cattle. Looking at the gross margin analysis of all the different feed rations, mucuna was the costliest option, but it achieved the highest gross profit margin per animal.

ProAgri Botswana / Namibia / Zimbabwe 12

Forage seed production Prof Dube also suggested that forage seed production should be investigated in some parts of Namibia to improve pastures and provide fodder for livestock, improve soil (nitrogen fixation from legume crops, crop rotations, cover crops, et cetera), and diversify farm income sources. The crops with the best gross margin were lablab and mucuna, followed by cowpea. It was widely adopted in Zimbabwe where it was planted in rotation with cereals. After planting mucuna, farmers found that the soil was significantly more fertile as a result of nitrogen fixation. They also realised that mucuna seeds have a market value and started selling it to other farmers and development organisations. Indicative of the value farmers place on forage plants, mucuna seeds sold in 2014 in the Beitbridge area generated US$11 000. In 2018, seed sales for that area amounted to approximately US$50 000. Mini-feedlot Prof Dube also shared his experience in the establishment and running of small feedlots as registered companies in the communal setting. These feedlots are small and not costly, but are proving to be very effective for the finishing of animals on a relatively small scale in a sustainable and viable way, with inputs grown by the farmers or surrounding farmers. Conclusions In conclusion, Prof Dube indicated that mucuna and groundnut-based diets produce viable returns when fed to livestock, and that these technologies are easily adopted by smallholder farmers. He said that supplementing beef cattle with alternative protein sources grown in the location is a viable option in smallholder systems. Prof Dube believes that the private sector and other market players need to be involved to strengthen the market.

*The National Rangeland Management Policy (NRMP) was approved in 2012. In 2014, the NRMPS Project was commissioned in support of this policy under the Ministry of Agriculture, Water and Forestry (MAWF), to address the declining natural resource base in Namibia.

Manage your costs to mitigate COVID-19 impact

he outbreak of Covid-19 across the globe is presenting a unique set of challenges to industries and causing severe disruption to global value chains, says Standard Bank’s Head of Agribusiness, Gerhard Mukuahima. He adds that this is especially true in relation to agriculture, raising questions and concerns about how the locking down of countries worldwide creates challenges for farmers to achieve the profits they budgeted for at the start of the season. Gerhard proposes a number of areas that can be looked at to continue making profits without compromising on quality of farm produce. “Cutting costs without compromising on quality may seem like an oxymoron, however, you can save money by making small adjustments to various aspects on the farm operations, instead of just slashing costs in a single area,” he opines. Following are some of the ways one can implement to manage costs: 1. Pay less for your inputs While input costs are rising, your ability to secure inputs such as seeds, fertiliser, and animal feeds at the cheapest possible rate is a good place to start saving money. Depending on your supplier, what stops you from negotiating an early order programme with your supplier? 2. Keep track of key usage Naturally, you don’t want to deprive

your soil, crops or animals of key nutrients which could affect your quality and yield, so it’s important that you keep track of utilisation of key nutrients and prioritise their procurement. Saving on these inputs may seem like a small cost, however, depending on the scale of your operation it can make a difference in the numbers by end of the financial period. 3. Diversification So you’re a specialist maize farmer. You do this really well and you’d rather not venture into growing crops you don’t understand. However, by diversifying your rotation, and including new low-cost crops into your mix, you can spend less on maize related expenses. The same could be done with a livestock farming operation. Introduce new enterprises (particularly short-term based high-valued cash options), such as poultry or hydroponics fodder production, for example, in the farming operation so as to create mixture of income streams. 4. Postpone major upgrades and purchases If you’ve been planning to upgrade portions of infrastructures on the farm, or buy new equipment, perhaps it's best to defer such plans or ideas, unless it forms an essential part of your operation, and has immediate impact on your bottom line. New technologies and products are released regularly, which means

there’s always something new and trendy for you to try. Not all technologies will work in your operation, and spending money on products and equipment that don’t contribute to you saving money is not worth the investment. 5. Keep a close eye on pest management costs Pest management (weeds, insects and disease) can significantly drive up your costs, and in the dry season it’s important to keep a close eye on how much you’re spending on pesticides. Instead of applying/spraying for prevention on a weekly basis, you can reduce to once every two weeks. If you notice that it’s not working and that you’re inviting pests to the site, then you can revert back to more regular spraying. The less you spend on pest control, the easier it will be for you to reduce costs. There are a number of ways for you to reduce your costs and save towards new equipment or upgrades for the farm. Your knowledge and experience on the farm can allow you to save money in areas that you probably overlook in haste.

Mechanisation solutions for small farms T

o remain profitable and keep up with a competitive market, you need to have the right tools for the job. Depending on your type of farming, there is an overwhelming range of farm equipment to choose from that will make your life easier. This article will provide some broad guidelines to consider when shopping for farming equipment.

Your needs The first factor that you should consider is what do you need your machinery to do? There will be obvious differences between the needs of a crop farmer and that of a poultry farmer. Here are examples of the questions that you should be asking yourself: • Are you farming with crops or animals? • What animals, if any, will you farm with? • If you produce crops, what type of crops will you have and how big is the area that you intend to use?

Tractor implements The implements are the machines that really do all the work. Without implements the tractor has very limited purpose. The most popular implements are mowers, loaders, tillers, planters, ploughs, hay balers, manure spreaders and more. Once again you will have to decide which tool you need to make your farming easier. Also remember to buy the right size that will suit your tractor. The tractor’s power should be kept in mind when buying implements.

Harvesters These machines can be extremely expensive. They also come in different forms. A harvester can be self-propelled or used as an attachment to a tractor. Once again, you as the farmer should make sure what you need before you buy a machine to harvest crops. If you have only a small patch of land, you can consider hand-harvesting or even contracting harvesters rather than buying one.

Depending on how many animals and what type of animals you keep, you will need various types of equipment. Fencing will always be one of the most important things that you will need. Good fences will ensure that the animals are kept safe. Electric fences are also an option but can be avoided to save costs.

Once you have considered this, you will have a good idea of what you will need. But no matter what type of farming you plan, there are some machines that you will not be able to do without, the first being a good tractor. The tractor The tractor is very versatile machine that can be used for many different purposes. Every farm needs a tractor to move heavy loads or to draw implements on the fields. When choosing a tractor, the farmer once again is spoiled for choice. These machines come in all shapes and sizes and more importantly prices. On a small farm you should be able to manage with a compact, multi-purpose tractor that range from 15kw to 50kw.

Properly planned handling facilities will save time and money. Photo: agri4all.com Things to consider No matter what type of mechanical equipment you consider buying, the following aspects should always be kept in mind. Think of the price, the machine’s performance, and power that it can deliver. Will it suit your needs? Also think about how affordable and easily available the parts are to maintain the machines. The product support offered by the supplier will have an impact on your choice. The good news is that you do not need to go far to find good quality farming equipment.
