What’s happening

chewing the cud Astounding rural support The 6.3 magnitude earthquake which struck last Tuesday has rallied the rural community, but in a much different way to the September 4 earthquake. Over the past week we have seen the tragedy of February 22 unfold as emergency services and citizens worked tirelessly to rescue and recover those trapped in the debris. Although many Cantabrians have become all too familiar with the extensive damage caused by the recent earthquakes and aftershocks, the earthquake has etched a black mark in New Zealand’s history with the tragic loss of life. The wider rural community has fared comparatively well compared to the September 4 earthquake, which took its toll on farm chattels, spilling silos and dislodging rotary dairy shed platforms. Nonetheless it is reassuring that rural community groups such as Federated Farmers and Rural Women, just to name a couple, have pledged their support to those whose lives are now in limbo and seek refuge. Federated Farmers has been liaising with Fulton Hogan and Civil Defence to lend assistance through sourcing heavy machinery,

which will be needed to clear the silt and rubble when essential services such as power have been reconnected. Rural Women have also Lance Isbister been pro-active with Ashburton Guardian members offering rural reporter accommodation throughout the country for those families affected by the earthquake. Rural Women did a great job of immediately identifying the needs of Christchurch-based homecare companies (which supports the elderly and disabled) to source portable toilets so their needs are catered for. Local Rural Women efforts in supplying baking and bedding for those who have taken refuge in Mid Canterbury has shown how every little bit helps in providing the basics that we all too often take for granted. The members of these organsations have done an incredible job of rallying to the cause and offering their services to those in need. It just goes to show how the perception of the rural and urban divide can dissolve when there is a crisis.

The Wright man at the right time

Lance Isbister, Ashburton Guardian rural reporter

You’d have a hard time encouraging Mark Wright to blow his own trumpet, but the modest mixed farmer has done plenty to reinvigorate Young Farmers. Mr Wright will be standing down as the Young Farmers Aorangi regional chairperson after two years as he looks to focus more on the farm and family with bride-to-be Marthie Meyer. Mr Wright galvanised Pendarves Young Farmers Club four years ago when a large number of former members retired from the club at 30 years of age, leaving only four members left contemplating the future of the club. As Pendarves Young Farmers chairperson Mr Wright became proactive in recruiting more members, by giving farming mates a nudge to come along to the monthly meetings held at the Chertsey pub. “I knew I had a few mates who were keen to come along, their mates brought their mates along and it really grew from there.” Word of mouth saw Pendarves’ plight passed along quickly and club membership steadily grew as young farmers and members of the public sought a social forum with a rural bent. Mr Wright said the key to keep people coming back was to provide them with fun interactive activities which ensured new members were involved right from the start. “They need to be involved in an activity that incorporates everyone otherwise they don’t come back.” Some of the activities range from practical skill courses such as first aid, fencing through to boot challenges such as pest destruction, darts and cake baking, the latter proving to be Pendarves’ Achilles heel. The fishing charters and LMS were also very popular according to Mr Wright.

Mark Wright step down from the Young Farmers Aorangi chairperson role in late April to focus more on the farm and family when he will marry fiancé Marthie Meyer (right) later in the year. Mr Wright and fiancé Marthie Meyer, a fellow Young Farmer, have worked as a team to incorporate more administration in Young Farmers and introduced a calendar to make the organisation run more smoothly. The fact they both live under the same roof has enabled them to co-ordinate Aorangi Young Farmers initiatives more easily. “It’s quite handy to bounce ideas of each other,” the couple said.

Through his leadership Pendarves once again thrived and new leaders emerged and took over from Mr Wright who went on to become the Young Farmers Aorangi regional chairperson.

One of the initiatives Mr Wright helped to bring about was the investment of a term deposit from fundraisers, for Aorangi clubs to fund and support those who will go on to compete in the Young Farmer of the Year contest.

“At the time there were not that many people keen to be regional chairperson. Someone approached me at a meeting and before I knew it I was regional chairperson.”

In the meantime Mr Wright is in the midst of updating the Aorangi Farm Find Maps, a handy resource which shows where farmers are situated in the Aorangi region.

He is hoping the map booklet will be ready for sale by the end of this year, which means Young Farmer members throughout Mid Canterbury will be approaching stock agents, contractors, and vets to help them associate farmers with their farm’s location on the maps. Mr Wright said Young Farmers has changed a lot over the past three years and said it has a positive future with the membership steadily increasing. He will step down from his Young Farmers Aorangi chairperson position at the end of April, but is still keen to help out with Pendarves club events when he can afford the time. In the meantime he has his hands full with harvest, but is looking forward to the Pendarves Young Farmers’ Harvest Party, which will be held at the Pendarves Hall on March 26.

FAR harvest update Oilseed Rape Fungicide Trial – Makikihi, South Canterbury FAR/Biodiesel New Zealand Fungicide Trial: Makikihi, South Canterbury (courtesy of Mr Colin Hurst) Sown: 20 March 2010 Harvested: 24 January 2011 Sowing rate: 3 kg/ha Previous crop: Wheat Previous stubble management: Stubble burnt and incorporated by top working followed by deep ripping Yield Results: (corrected for % moisture)

This fungicide trial was designed to evaluate the benefit of autumn, winter and early spring fungicides for stem canker disease control. Stem canker (blackleg), also known as phoma in its asexual stage, is first identified in autumn when it attacks the leaves. In spring it attacks the base of the stem causing

premature senescence and sometimes lodging. A phoma infection assessment took place 21 days after the green bud spray application and with both untreated treatments showing the highest infection (18.8% of the plants affected). Proline applied at 4 leaf stage and then again 21 days later (both at a rate of 400 mls/ha) and Proline applied 21 days after 4 leaf and applied again at green bud (400 mls/ha) showed the lowest infection with only 6.9% of the plants affected (nearly half the site mean infection of 12.2%). Stem canker infection was scored 14 days prior to harvest and was found in every treatment. Where applications have been consecutive or repeated the stem canker scores were lower. The application of Proline (400mls/ha) at the three timings showing the lowest score (46.1% stems infected). The untreated plot had the highest infection with one scoring 80.9% of the plot being affected. Yields were good within this trial with a mean site yield of 5 t/ha. There was no significant difference between treatments within the trial. The highest yielding treatment was Proline 800 mls/ha applied 21 days after the 4 leaf stage with a yield of 5.12 t/ha (102% of the site mean). The lowest yielding being the untreated at 4.88 t/ha.

FAR harvest update Dryland Autumn Milling Wheat Cultivar Performance – Methven 2010 As well as a dry, late spring and early summer, the trial received a very strong north-west wind on 21 and 22 of December. This wind event caused severe lodging in some cultivars (see mean scores on a 0–10 scale, with 0=nil and 10=lodged), and shedding in some cultivars. Yield results reflect the straw strength and shedding resistance (the ability to resist wind damage) of the cultivars rather than their yield potential in better conditions. The trial received 257 kg N/ha over the season in five split applications. Previous cropping history: 09/10 Ryegrass seed, 08/09 Wheat

Sowing Date: May 5 Harvest Date: February 2 Soil Type: Lyndhurst silt loam Location: Methven Dryland yields at the Methven cultivar performance trial were lower when compared with the four year adjusted means for the other Canterbury dryland trial sites. Methven had a mean yield of 5.5 t/ha compared to the four year averages of Highbank 9.1 t/ha, Chertsey 6.8 t/ha and St Andrews 8.6 t/ha. The highest yielding cultivars were Phoenix and CRWT151 which performed statistically better than the other cultivars at this site.

Social media = social responsibility Neal Shaw, ATS Chief Executive

Social media is no longer just the domain of the younger generation. Online media such as Facebook and Twitter, where people can share information quickly and easily with their friends and peers, have become an everyday part of life for many households.

But with many people having potentially hundreds of online friends, and the ability to circulate opinions quickly without any checks in place, the damage caused by misinformed or incorrect comments could be huge.

Its immediacy and popularity has also become an increasingly popular marketing tool and many businesses are now using Facebook and the like to reach their customers.

In this instance I was able to quickly and easily track down the person who had made the posting (through their online profile) and I was able to discuss the customer service complaint and resolve the perceived problem very quickly. I pointed out to the person involved that there was an etiquette involved in making a complaint, and I asked how they would feel if I had used Facebook to warn other retailers of their behaviour without notifying them.

But there are many warnings which come with social media usage and it is common to see news items cautioning the risks and potential pitfalls of using these sites. Recently I experienced such an incident within our business. It was brought to my attention that there had been a posting on a Facebook page criticising the level of service received in an Ashburton Trading Society (ATS) retail shop. The posting concerned me on a number of levels. The first was obviously the perception there was a customer service issue. Secondly, I was also concerned the posting had been made without giving ATS the opportunity to try and rectify the perceived issue in the first instance. Before the introduction of such websites, the expectation was that word of mouth would result in a customer telling 10 others of a bad customer service experience.

Following our discussion, the postings related to ATS were promptly removed by the writer. I wanted to make the point that basic etiquette rules should still apply to social media, and in fact it is highly important it does, because these networks are powerful in their size, speed and accessibility. Even when postings are removed there’s still the ability to retrieve them – they never truly disappear. It’s for this reason there is growing momentum and awareness for change, and the need for a more considered and careful approach to what is posted. We are already aware the media uses these websites for

background information on news stories, and potential employers also use them to check the character of job applicants. We have even had a situation where a potential employee had posted on their Facebook page that they were coming to work for ATS. They had not resigned from their previous position or signed the contract with ATS - such is the naivety of the younger age segment using electronic social media sites. As an employer these sites provide the opportunity to assess whether an applicant will understand the level of appropriateness which is relevant to our business. All businesses have required standards, but as yet there doesn’t appear to be any real level of etiquette on many social media sites, and as a result, many users have not developed a good understanding of protocol and ethics. In the past the only way to really broadcast opinions or exploits was to take out an advertisement in a newspaper or become the news item. These were always peer reviewed and have plenty of checks and measures in place to ensure accuracy and an unbiased approach. There are no such checks and measures in place on social media sites, and it is very difficult for the general public to defend themselves after the fact. We wouldn’t dream of standing on a chair in a crowded room to tell everyone what

we’ve been up to during the day, so why should we feel so comfortable about sharing all of these details with “friends” – sometimes so far removed from us they should really fall into the category of strangers. It is a huge risk to post private information in the misguided belief only a select few will read it. The potential is much greater and isn’t necessarily short-lived. Some of these postings will come back to haunt many in years to come. I’m not saying people shouldn’t be able to express themselves – but there is a proper and safe way to do it. If someone experiences a problem with customer service, a co-worker or a boss they should confront them and deal with the issue face to face. They shouldn’t use social media sites to vent their feelings on such important issues without trying to solve the problem first. The reality is they are probably going to end up making the problem worse. Comments made on these sites will be shared and they have the ability to act like chinese whispers, distorting facts while gaining momentum and potentially escalating a situation. These sites can be powerful and have much to offer but should be treated with respect and caution to best serve all users.

Irrigation

Irrigation New Zealand Inc www.irrigationnz.co.nz

Irrigation with collective opportunity versus individual The Ashburton spray irrigators group was formed in the 1970s to explore the opportunity to gain cheaper power prices. At that time there were new technologies, namely the drilling of bores and submersible pumps that had opened up opportunities for further exploration of water resources. The price of fossil fuels, the traditional source of energy for irrigation, was also on the rise. Through some very direct linkages the group was successful in lobbying the government to secure power prices and recognised the fact that their use was not contributing to the peak load in the winter months. This was of direct benefit to their members, the wider irrigation community had continued to have benefits as increasing numbers of irrigators used electricity as the preferred source of energy. The ability to achieve this outcome rested in the collective representation that the group held. The force of growing numbers and a compelling argument put forward by credible representatives through direct involvement in the issue meant that their voice was heard and taken seriously. There have been other times that the Ashburton spray irrigators group has successfully facilitated benefits for the irrigators. The negotiation of contracts through the Ashburton Trading Society

(ATS) with the power generating companies is another example where the collective action of the group directly benefitted the individual irrigator. The group has lapsed with personnel moving out of the district and no fires to fight at the present time. That is not to say there is no smoke on the horizon. The neighbouring Rakaia Selwyn zone consent reviews were a huge challenge to the irrigators in that area. This is an ongoing and protracted process that has sapped resources and strained relationships. The Ellesmere Irrigation Society was formed as a direct response to that process and a comment made by an involved member was that if they had been an organised group earlier they would not have had such a big problem to deal with. The irrigators were caught on the back foot, but as a recognised group they are able to have a voice, be proactive and involved at the local and regional level of policy making and planning. Along the same lines as the Ashburton group they have negotiated a favourable electricity deal with an electricity provider and have set up their own telemetry network enabling better management of their irrigation practices in relation to the consent conditions they work under. The ability to be proactive is not to be

underestimated. If irrigators are not focused and spending resources on waging a battle, but instead are able to influence and have an input into processes the battles may be avoided. To be a recognised group that has the ability to be consulted and the ability to contribute allows the individual irrigators an influence that they don’t have alone. Collective gains can be far greater than individual if acting as a co-ordinated group. So what are the possibilities in the Ashburton district? With much the same issues around water use efficiency and water quality as the neighbours in the north if we can be proactive and organised the hurdles

will not be insurmountable. The new zonal committee structure and Environment Canterbury are actively pushing for water user groups to signal the pathway. If you are not involved you will not have an effective voice. A meeting, hosted by IrrigationNZ and Mid Canterbury Federated Farmers scheduled for March 24 at the Hotel Ashburton at 1.30pm, is the first step to get involved and take control of how your water resource will be managed in the future. All irrigators are urged to attend. Get involved take control come to the meeting!

Autumn sowing options Forage cereals are used to produce large volumes of quality feed, providing feed for animals during periods when pasture growth does not meet demand. They can either be grazed or harvested as silage. They are easy to establish and are therefore ideal as a break-crop when renewing old pastures. Forage cereals have a distinct advantage over other winter crops where the paddock cannot be planted until midautumn, because they have a greater ability to grow in cool conditions. The large seed allows them to be planted with less preparation, saving time and money, and improving success rates. Direct-drilling forage cereals into droughtdamaged pastures is an excellent way to generate rapid feed recovery after a drought. Oats or triticale are commonly planted in autumn to provide grazing in winter and can produce 5-8 tonnes DM/ha at grazing. Oats can regrow after a careful grazing in early winter (May) in mild-warm climates. Oats or triticale are the preferred crops to grow between maize crops, producing more green-chop silage (up to 44 per cent) than annual ryegrass and being harvested at an ideal time for re-planting of maize. Triticale can be planted throughout winter and early spring to produce whole-crop cereal silage (WCCS). The silage has similar properties to maize silage (high in carbohydrates), but grows in winter and spring and is harvested in early summer.

restricts amounts of grass silage that can be harvested. Barley Barley is planted in spring for whole-crop silage. It matures quicker than triticale, so becomes the preferred species when crops cannot be planted until mid to latespring, or in dryland climates. Barley is also used as a stepping stone for establishing Lucerne.

Oats Forage oats provide a large amount of feed for a single grazing during winter. They can be planted in February for earlywinter grazing, through to April – May in mild climates for late-winter grazing. Oats are also popular for growing between maize crops and harvesting for green silage in September, because they can produce 44 per cent more than annual ryegrass and are up to $600 per hectare more profitable to grow. Oats are also planted in early spring to produce green-chop silage. This is an Triticale effective way Triticale is a cross between wheat and to ensure adequate silage storage in ryecorn. Most autumn- planted triticale districts where dry spring weather often cultivars can only be grazed once, but DoubleTake is the only triticale that will reliably grow back after grazing, and can be grazed one to two times in winter and then kept for spring silage production. Triticale is also planted in winter and earlyspring for whole- crop silage production, with no grazing.

Establishment Forage cereals are relatively simple and reliable to establish, but some details are different to establishing pastures. Forage cereals are one of the key tools for farmers to economically increase the amount of feed produced on their farm. As with most tools, they need to be used correctly to get the best from them. Farmers should seek advice from a local seed retailer with good field experience. Time of sowing is critical for autumn forage cereals, as it has a major impact on total yield, days to first grazing, and quality at grazing. Oats planted in late February and March will provide high yields for grazing in mid to late winter, whereas May planting is suitable for spring green-chop silage production. Paddock preparation is less critical than for new pastures, as cereal seed is less sensitive to deep sowing, and they are more competitive with weeds. Best results however will be achieved from paddocks that have been sprayed

and carefully cultivated, or sprayed and direct-drilled. It is very important to drill nitrogen-based fertiliser (e.g. 150- 250 kg/ ha DAP) with the seed, especially when direct drilling. Seed should be drilled at 3-4 cm, depending on soil density. Shallow drilling (<2 cm, e.g. roller drills) or broadcasting is not recommended as it increases the chances of bird theft. Oats are sown at about 100 kg/ha. Triticale seed is much larger than oat seed, so the sowing rates must be higher (e.g. 140-180 kg/ha). Post-establishment fertiliser is necessary on most crops to achieve reasonable yields. The establishment fertiliser should be enough until after the first grazing with early planted triticale crops, when nitrogen (40-70 kg N/ha) should be applied. Oat crops will need at least one nitrogen application if grazed in winter, and two if grown for silage in spring. Application rates will depend on paddock history, soil type, and previous leaching. Avoid applying within four weeks of grazing as this increases risks of nitrate toxicity. Management Early grazing of triticale is very important for subsequent production. It should be grazed when it reaches 20cm in height (can be 60-90 days after planting). Graze animals for a short duration (one day) and move them to leave a 10cm (1200-1500 kg DM/ha) residual. Backfencing is essential. If you want to restrict animal intake, a runoff paddock may be needed so that the triticale is only grazed for part of the day. Avoid grazing when the soil is wet and soft enough to cause any pugging, because this will severely reduce recovery. The second grazing should be done in a similar manner. If the crop is to be kept for whole-crop cereal silage in spring, grazing should be completed by the end of August. Grazing of oats is usually done by strip grazing, so that intakes can be restricted and utilisation maximised. Crops should be grazed before they become too mature because feed quality will decline as leaves turn from green to yellow, and the proportion of stem increases. Over-mature oats can have low protein levels, so are not suitable for grazing with pregnant ewes within three weeks of lambing, or with young male deer.

Autumn sowing options

Why is sowing depth so important? Sowing depth is critical. Oats planted on the surface will give you an amazingly poor strike. Put the same seed line into the ground 50mm (two inches) and the different germination will amaze you. It’s all about seed sowing depth. Similarly Clover, place it 75mm deep and you’ll be lucky to see it. As a general rule – sow small seeds shallow, sow big seeds deeper.

that had been driven over by the quad weighed at 24 tonne / Ha, while the rest of the paddock weighed only 13 tonne / Ha. The extra $60.00 / Ha to give it all another roll would have been well worth it, costing only another $0.005c / Kg DM! Try it yourself. The less consolidated the comparative area, the bigger the difference will be.

Does soil temperature influence germination? Sure does. According to Pasture and Crop Science by White and Hodgson - Effect of temperature on the germination rate of pasture species, expressed as the number of days to reach 75% germination of viable seed Soil Temperature (°C) Species 5 5-10 10 15 20

Why is this? As seed germinates, it requires moisture and nutrients to be able to continue growth. If the soil structure near the new developing root structure is loose, the root structure will be unsuccessful in penetrating the soil, causing seed mortality. Can we over compact soils? Yes, especially heavier soils. We would normally say that you would want to be able to place your boot into the soil no deeper than the sole of the boot to be suitable for sowing and then give it another roll after sowing.

Is consolidation of seed bed prior to sowing important? Yes, very important. One example of a Swede paddock planted into a pumice soil type was rolled once, sown and harrowed. The farmer then drove through the paddock on his quad a couple of times to view the establishment. When the crop was measured, the area

Sowing rate - are our rye and clover sowing rates too high? At times, we tend to think they are too high. We often hear of farmers and contractors sowing small seed permanent pastures at 35 Kg / Ha.

Not the biggest, but one of the best!

This will look great at initial grazing, but then get yellower and yellower as interplant competition comes into effect. Should the following summer be dry, you can virtually guarantee you’ll have a patchy paddock with lots of bare ground and weed invasion. What sowing rate should we be planting at? There are a few people out there claiming that we should only be sowing Ryegrass

at 10 Kg / Ha. Farmers sow at this low rate when they are trying to produce seed. They are growing Ryegrass alone, and use a lot of chemicals to keep the sward pure. However, this is not the case in a permanent pasture situation. Each seed variety has a thousand seed weight. This tells us what one thousand seeds of a certain seed variety weighs. We arrive at sowing rates based on previous experiences as much as anything.

Plants cloned as seeds Plants have for the first time been cloned as seeds. The research by UC Davis plant scientists and their international collaborators, published February 18 in the journal Science, is a major step toward making hybrid crop plants that can retain favorable traits from generation to generation. UC Davis assistant professor of plant biology Simon Chan said most successful crop varieties are hybrids. But when hybrids go through sexual reproduction, their traits, such as fruit size or frost resistance, get scrambled and may be lost. “We’re trying to make a hybrid that breeds true,” Prof Chan said, so that plants grown from the seed would be genetically identical to one parent. Some plants, especially fruit trees, can be cloned from cuttings, but this approach is impractical for most crops. Other plants, especially weeds such as hawkweed and dandelions, can produce true seeds that are clones of themselves without sexual reproduction — a still poorly understood process called apomixis. Prof Chan said the new discovery gets to the same result as apomixis, although by a different route. Normally, eggs and sperm are haploid - they have half the number of chromosomes of the parent. The fertilised egg and the adult plant it grows into are diploid - containing a full complement of chromosomes, half contributed by each parent. Prof Chan and his colleagues focused their work on the laboratory plant

Arabidopsis, which has certain genetic mutations that allow it to produce diploid eggs without sexual recombination. These eggs have the same genes and number of chromosomes as their parents. But those eggs cannot be grown into adult plants without fertilisation by sperm, which adds another parent’s set of chromosomes. Last year, Prof Chan and UC Davis post-doctoral researcher Maruthachalam Ravi showed that they could breed haploid Arabidopsis plants that carried chromosomes from only one parent. They introduced a genetic change so that after the eggs were fertilised, the chromosomes from one of the parents were eliminated. Such haploid plants would reduce the time needed to breed new varieties. In the new study, Prof Chan’s lab, with colleagues from India and France, crossed these Arabidopsis plants programmed to eliminate a parent’s genes with either of two mutants that can produce diploid eggs. In about one-third of the seeds produced, the diploid eggs were successfully fertilised, then the chromosomes from one parent were eliminated, leaving a diploid seed that was a clone of one of its parents. Ravi described the result as a step on the way toward artificial apomixis. The team hopes to produce crop plants, such as lettuce and tomato that can fertilise themselves and produce clonal seeds.

Nutrient management

Lachlan McKenzie, Federated Farmers Dairy Chairperson

Water quality issues have been around for a long time. The old Ministry of Works built many schemes in the 1960s as the government of the day recognised the benefits of storing water.

even discussed with farmers who are the resource manager and the most affected party. As a nation we have just started to address the issues of eutrophication, or excess nutrients that stimulate aquatic plant growth.

These schemes essentially used border dykes or irrigation built into a slanting paddock. The majority have now been upgraded by farmers to spray irrigation with a corresponding improvement in water use efficiency and a reduction in nutrient losses. This is a very good story. But people outside of agriculture who don’t understand this, now see big shiny alloy structures spraying water with concern. Before, they would never have noticed water running off the border and down the drain along with the nutrients we are working hard to minimise. There is still huge potential for dairy growth in many parts of New Zealand. The issue we all now face is the growing requirement for nutrient management. I acknowledge that intensive food production can have more nutrient losses than broad acre or extensive farming. But we also have to acknowledge the world demand for food is increasing. Government articulates the importance of dairy to our economic and social wellbeing.

Page 13

Yet when it comes the catchment scale there has been an absence of forward thinking because what we are talking about is truly intergenerational.

We have several challenges as representative of our dairy sector. • How do we show we understand the community’s views? • How do we articulate our goals and aspirations to our communities? We have to show we have similar aspirations and goals. We know in the minds of some that irrigation and dairying creates irrational fear and anxiety. We also know some lobby groups play on this fear for their own political and financial benefit. Part of our role as farmers is to understand these fears and concerns to better explain the true picture. We need to use sound

science, facts and an absence of emotion to show how we are focused on solutions and progress. It frustrates me that in our modern and highly educated society that some socalled scientists and regulators exhibit a narrow-mindedness. They fail to comprehend the complexity of the issues involved in the land and water interface. Some are of our industry’s making but most environmental impacts are not. Yet their only solution is to literally shut down dairying. All too often and before such solutions are proposed, the real issues have not been clearly articulated, documented or not

As for sound analysis, we face too many assumptions over our industry’s impact pushed by some politicians for personal aggrandisement. I refer specifically to the Green Party. We want to talk science and reason and they prefer the sucker punch. Getting soundness around this is a role for Federated Farmers. We need to work within and outside of the industry to turn this thinking from assumed links to factual evidence. I have personally done the numbers in some catchments and converting just 1.5 per cent of the farm area into intensive wetland plants such as water cress and then harvested could halve the nitrogen and phosphate loss to water bodies. Where is the old kiwi “can-do attitude” in solving these issues?

ACL are passionate about providing a one stop solution,

Yeatman Brothers began involvement in irrigation reservoir construction in 1976, at that time it was considered an eccentric distraction from the then predominant borderdyke irrigation development. Many borderdyke irrigators at the time considered the feasibility of water storage for improved irrigation efficiency but the large volumes of water required for borderdyke irrigation usually made reservoir construction prohibitive. However a small number of reservoirs were constructed in the early days. Learning the processes used in these and large scale civil works, such as the upper Waitaki and a number of district council sewage pond projects. Nick, Hoss and their team acquired the skills and knowledge of how to do it right the first time. When large travelling irrigation systems came on stream in the 1990s, the reservoir boom took off, and many thought then and still do today an irrigation reservoir was a cut to fill exercise to build a primitive bund. The porous and varying nature of Canterbury soils soon revealed the deficiencies of simplistic and under engineered ponds. Yeatman Brothers usually take a bit longer to complete their pond projects but long term experience, proven

Pond construction Transform a sludge-filled liability into a fertiliser-filled asset Through continuous research, development and testing, Plucks have developed the market leading design in effluent pond stirrers. This design gently and continuously stirs the effluent, making sure that a crust doesn’t form on the top of the pond, and there isn’t a thick layer of sludge settling at the bottom. It’s all about oxygen. Ample oxygen supply in a waste water pond system is the key to rapid and effective dairy effluent treatment. Without sufficient oxygen being present, bacteria are not able to quickly biodegrade the incoming organic matter. In the absence of oxygen, degradation must occur under septic conditions which are slow, odorous and yield incomplete conversions of pollutants. For example, two stage ponds designed to biodegrade waste water pollutants without oxygen must hold the incoming waste water for six months or longer, (without any further waste water coming in) to achieve acceptable levels of pollution removal. This is because the breaking down of organic matter in the absence of oxygen is a very slow process. Adequate stirring or mixing,

to keep the pond’s content in suspension, is also an important element. With mixing, incoming pollutants and waste water are better distributed throughout the entire pond volume. This results in more uniform and efficient treatment. In addition, solids that settle are suspended by the mixing action and brought back into contact with the microbial population floating throughout the pond. Poor mixing has the effect of creating thick solid deposits that fall to the pond floor before proper treatment has occurred. This causes improperly treated solids to fall away from the active, overhead treatment process. It also creates septic conditions on the pond floor which, in themselves, pull available oxygen out of the upper layers of the pond and reduce the effectiveness of treatment in the upper zone. When this occurs, the sludge builds up to a point where it effectively eliminates the main advantage of a large pond system because the capacity of the pond is getting smaller every day. Plucks have worked with an

Auckland company who are specialists in mixing large volumes of liquid, and have learnt how to keep the effluent pond continuously moving, but at a very low horsepower. It would have been easy to create a powerful machine to do the job, but this would create a massive power bill. Making it as cost effective as possible for the farmer was a top priority. Once the stirrer is first installed, it takes three months or slightly longer to fully blend the pond contents, but once this is achieved, there is a constant, rich effluent potion ready to be applied to paddocks, with no black sludge leaving black lines over the ground. Whether it is a plant upgrade or a new facility, a pond system will not work well without proper treatment. As sludge disposal regulations become stricter and disposal sites become scarce, proper aeration and/or mixing will completely eliminate the need to mechanically remove solids from the effluent ponds.

Where are we going wrong? John Leadley

In recent times, seemingly after nearly every weekend our newspapers are full of the exploits of young persons and teenagers affected by drugs or alcohol, and the consequences of their actions. This is not only a local problem but an alarming issue nationally. Dr Paul Fairfax, head of the Emergency Department at Wellington Hospital provided the following figures. 40 per cent of all admissions to Wellington Hospital for drunkenness are aged under 20 years – some as young as 13-years-old. No one can factor can be cited as the major cause of this alarming statistic – and I’m not suggesting for one minute that 95 per cent of teenagers today are any more wayward than those of previous generations. What I do know from observation and crime statistics is that those that are bad are really bad, and I mean really bad. Lack of respect for others and for both public and private property is a national concern, and not limited to teenagers. Vandalism repair alone is responsible for 1 per cent of the Ashburton District’s rate take. Road signs, playground equipment, fences, mailboxes, public toilets, gardens, school property, the list goes on. And again it’s not only teenagers. Undoubtedly easy access to alcohol at a young age is a major part of the issue. Promotion of low cost ready to drink products, often with an alcohol level of 8 per cent or above, certainly is part of

the problem. Maybe our teenagers have access to too much money? Just check the footpaths and gardens around the CBD after the weekend! The mayhem surrounding the recent “party” at Balmoral Hall would surely leave no responsible parent with a sense of pride. This was not a one-off event, merely symptomatic of 2011. For the resources available, I believe our police, town watch, town ambassadors and security firms do a wonderful job in very difficult and challenging circumstances. These agencies are significantly hamstrung by political correctness and a weak kneed judicial system, making so-called punishment ineffectual. Fifty years ago many teenagers were literally scared of the police and certainly if not scared at least respectful of police, their parents and others in authority. Seemingly not so today, in a sizeable minority of cases. Mobile in-your-face teenagers with a know-it-all attitude to authority constantly challenge police verbally, and with increasing concern, physically. Arrogant, hooded (even in mid-summer) and devoid of eye contact they tend to hunt in packs, aided by ever present texting. Quite probably this behaviour is initiated by hours of watching all too readily available crime movies on film, Television and video. Whatever the cause for this decline in

values of young people it requires an urgent multi-faceted approach if essential human values of pride and respect are to be maintained. I don’t buy the popular argument that immigration is part of the issue. In the Auckland police district, Chinese make up 10 per cent of the population – they appear in just 2 per cent of the crime statistics. Statistics for Ashburton District counter the common belief that new settlers commit a disproportionate percentage of crime. One fact that is clear is the strong correlation between employment and crime. How often the terms sickness beneficiary or unemployed appear in court! It’s surprising how many little “Jonnies” are either too light for heavy work or too heavy for light work! What’s really lacking is motivation. Moreover the overused complaint “There’s nothing to do in Ashburton” has no credence. Countless sports, cultural, service, recreational, social and church related clubs provide a multitude of opportunities for any motivated person, young or old, catering for all land, water and air pursuits at all levels of fitness. Some parents want to blame teachers for lack of discipline and poor motivation. Clearly an opt out. It’s my view that the real cause of the current degradation of standards comes

from the home environment – put simply, poor parenting. Twenty percent of New Zealand’s children come from homes where welfare payments are the major source of income. It’s surely more than coincidental that this same group feature strongly in the larger than average family size. Intergenerational unemployment is a cycle that seems almost unbreakable. An over generous welfare system does nothing to fracture the cycle. I certainly don’t pretend to be an authority on successful parenting but I have some views I’m willing to share. Firstly I believe the greatest gift you can give your children is time, time to share experiences, to teach motivation, to reward good results, to reprimand misdemeanours, to build pride and a sense of responsibility and tolerance. To build respect you need to share respect showing an ability to listen. I find the statistics for numbers of children born out of wedlock alarming – but not an automatic precursor to teenage delinquency. It always comes back to parenting. Like employment, the ability to have children should be seen as a privilege rather than a right. We should all take the role of parenthood seriously. The rewards are immense.

Winchmore update – February

John Carson

Sitting here at my desk early morning (24th) still shocked at what we have seen and heard these past few days to the people of Christchurch, people we know and the ones we don’t. Where do we start to help? What can we do to help? Apart from the obvious, by donating what we can in goods, time or money, I think we as farmers can appreciate the cost that this is going to have to the whole of New Zealand and as major export earners the call will be upon us to put in the extra effort to ensure our produce and production is at the maximum and the best that we can deliver. We can look at this disaster and feel helpless or we can ask ourselves what we need to do to fine tune our farming operation to maximise market returns and export earnings for New Zealand. No matter what our work involves and no matter if town or country, by doing what we do best we will be contributing. Here at Winchmore, February to date has been average, according to the long term metservice data. Our rainfall is slightly below normal at 41.2 mm and our soil temp is slowly decreasing from the 18 to 20°C range down to 15.5°C. Even the very hot day last week at 29.9°C only ranked 34th from the past 50 years. The highest February daily temperature was in 1973 at 38.5°C. Three more science trials have just started and so we are back to some more little paddocks fenced with flexi

netting and small mobs of lambs and young calves. Science has it all under control, it is looking quite complicated to me but in time it will all become clear as the shifts become more regular and a pattern develops. It is probably easier to make sense of the system they use if you are good at playing chess or Chinese checkers. While it is good to have the opportunity to utilise our stock and pasture it does mean that longer-term plans need to be much more flexible and that to me is the challenge of being available for research and also to be

a commercially viable enterprise. This makes the dairy support system a very important part of the farm’s income and development. Pasture growth is back to normal after slipping slightly in January and now with 340 lambs and cull ewes gone it has been easier to keep good lengthy pasture up to the dairy grazers and to flush the ewes before mating. The R2 heifers have just been pregnancy tested with only two scanned empty, a pleasing result.

Autumn: A tricky time owners ‘Dairy Cow-it is’forinhorse Horses! Growth mode: why do horses develop health and behavioural problems in Autumn?

As I am writing this article it is raining steadily and with ground temperatures still plenty warm enough for growth and sunny days ahead it is a recipe for horses to start doing ‘naughty’ things out of the blue, get bouts of ‘colic’, laminitis, headflicking, swellings in various parts of the body (see picture where weird swellings are evident on the cheeks), and are prone to muscle soreness and ‘stiffness’ especially in the sacro-iliac area and the hind-quarters.

Chances are the bucking will no longer be a problem after a few weeks on the right diet and the whole horse will be back to normal.

A horse with ‘dairy cow-it is’! Look at the similarities in condition. A combination of the following points will get excellent results. 1. Feed as much hay as the horse will eat. If your horse is chronically thin and has soft to sloppy manure, you may need to turn an area into a ‘dry lot’ by spraying out or scraping the grass off. This is the best thing you can do to ensure the flora in the hind-gut is healthy. 2. Feed the right minerals.

tevens Seeds Ltd is an independent Grain and Seed Company based in the heart of New Zealand’s grain and seed producing area, within the Industrial Estate, Ashburton. Being independently owned allows owner Peter Stevens to offer the farming community his immense knowledge to gain the best performance, yield and cleanliness of all crops grown and sold. Peter has a hands-on philosophy in terms of all crop monitoring, giving his clients expert advice on the most effective solutions to maximising crop yields. Peter’s main area of expertise involves importing specialist overseas varieties, growing them in New Zealand and then re-exporting back to the breeder overseas. This enables the plant breeder to cut the number of years from conception to the market place, and maximising two harvests in one year. A new concept developed by Stevens Seeds is their Perenmore Diploid Perennial Ryegrass. This is an economical nil endophyte later seeding persistent ryegrass that has proved very palatable. It is similar to the Nui variety, but seeds substantially later, giving more longevity for grazing. It is easily established in both cultivated seedbed and direct drilling situations. It is a fantastic option for providing great pasture, at a similar cost to traditional pastures such as Nui. It is ideal in permanent pasture mixes. Stevens Seeds has a growing reputation for exporting high quality, nutritional food supplies to different corners of the globe. Their Promore White Lupins are currently being exported to the Middle East, where they are soaked and prepared as a high protein food alternative.

Scheme takes shape

Motorscrapers are currently stripping the storage pond site of the Rangitata South Irrigation Scheme on the south bank of the Rangitata River at Arundel, with more men, machines and equipment to follow as the initial pond and race construction ramps up. The innovative irrigation scheme will utilise a “water harvesting and storage” strategy to divert water from the Rangitata River when flows exceed 110cumecs. This water will subsequently be used to irrigate a gross area of up to 16,000 hectares within a command area of 20,000 hectares, situated between the Rangitata and Orari Rivers, which extends from Arundel to the coast. The scheme involves the diversion of 20 cumecs of water from the Rangitata River into a series of seven stepped storage ponds at Arundel. The total storage capacity of the seven ponds will be 16.5 million cubic metres (m3) with a maximum depth of 8.0m and a total surface area of 300ha. The seven ponds will require the movement and placing of 3 million m3 of local soil and gravel to construct the pond embankments and lining layers. As well as the vast quantity of pond earthworks there are numerous concrete structures collectively requiring in excess of 1000 m3 of concrete, 20 hydraulic gate

At the end of March the business will be going through another transformation to allow for further growth and development. Stevens Seeds will be shifting its operation to the Izone Business Park in Rolleston, Christchurch. Peter will strive to retain local relationships and has plans to stock a large supply of seed and grain within Ashburton for immediate distribution to clients.

systems and 35 off-take structures and water metering points along the scheme. The race network comprises 70km of open race over three separate legs. The initial race carries 6.0 cumecs of water via a 10m wide and 2m deep race eventually reducing to 0.25 cumecs via 2.8m wide races as the scheme water makes its way towards the coast. For the past five years the scheme design and consenting has been driven by Gary Rooney and the Rangitata South Board and has been designed entirely in-house by REL engineers and staff, with external design support and review by Damwatch. A critical feature of any modern irrigation scheme is the control of the abstraction of water from the river and ability to restrict fish access to the ponds and races. The control gates consist of three large steel slide gates, concrete headwalls and three large diameter concrete pipes which convey the water through to the initial race. The slide gates are hydraulically operated and will be automatically opened and controlled to pass the minimum flow of 1.4 cumecs, up to the maximum flow of 22.5 cumecs in accordance with Resource Consent requirements.

A fish barrier is provided at the face of the river. This consists of 14 rolled galvanised steel mesh gallery drums embedded into the face of a 250m long embankment. The gallery drums are open but surrounded with free draining river stones, with the outer face of this embankment protected with large rock rip rap.

the abstraction and delivery of the correct quantities of water, as well as to indicate problems that need immediate attention. This scheme is not just about the taking of water for irrigation, it is also giving something back to the river system that is making it all possible. In addition to the irrigation water take, a further abstraction of 1.4 to 2.5 cumecs has been earmarked to supply a fish spawning race. This race will be developed on the northern side of the storage pond area and terminate back into an active braid of the Rangitata River, thus enabling populations of local sport fish to spawn and for their fry to safely make their way back to the river.

This enables the abstraction water to freely percolate through the screens but prevents fish from entering and being trapped in the scheme’s races and ponds. The storage ponds will release up to 7.0 cumecs of water into a series of water races based on the existing stock water race network which is to be extensively upgraded. This upgrade will include some realignment, regrading, resizing and replacement of culverts and road crossings. The water will then be supplied to each irrigator directly into an on-farm storage pond. Each on -farm storage pond is required to have a minimum of 250 cubic metres of storage capacity per hectare of irrigation which equates to one Rooney Earthmoving’s D375 bulldozer removes one of many tree stumps week of on-farm storage.

A beneficial effect is also expected over the whole region but especially in the local service towns of Geraldine and Temuka as well as the larger population centres of Ashburton and Timaru, as extra farm expenditure from increased farm productivity makes its way to businesses, contractors and rural service providers in these centres.

Weather by the moon Ken Ring

You cannot tear a piece of paper twice in the same place Perhaps at this time of shock and disbelief it is untimely to question geologists, who are trying their best to find answers for our worst catastrophe. But I do feel some questions have gone unanswered for too long. This earthquake that smashed buildings, cracked roads and twisted rail lines in Christchurch ripped a new 3.5m-wide fault line in the Earth’s surface. A Canterbury University geology professor said “a new fault” had ripped across the globe and pushed surface areas up. He said the quake was caused by the collision of the Pacific and Australian tectonic plates. “One side of the Earth has lurched to the right - up to 11 feet (3.5m) and in some places been thrust up,” he said, and New Zealand sits above where two tectonic plates collide. New Zealand’s last major earthquake registered 7.8 mag and hit Fiordland on July 16, 2009 (just before new moon+closest perigee), moving the southern tip of the country 30cm closer to Australia. The January earthquake that rocked Haiti was also unleashed by a previously undetected fault line - not the well-known one scientists initially blamed, according Eric Calais, a professor of geophysics at Purdue University in West Lafayette, Ind. He said the mag-7.0 earthquake occurred along this newly uncovered fault and not the well-documented Enriquillo fault. US based geophyscist Ross Stein noted that even in California about half of all moderate or stronger quakes occur on previously unknown faults. But perhaps these “newly discovered” faults were unknown because they weren’t actually there before the earthquakes occurred! Do plates collide or were they once one piece that got broken into two by an event? Surely a fault line should be renamed Previous Rupture Line. I question that any fault line was ever

there first, before any force or molten matter decided to break through at that point. It is more likely that the earthquake/volcano etc comes through to the surface wherever it wants to, and this creates a weak section in the crust, through which later events may follow if stresses occur in the immediate vicinity. Seeing a fault line host a new earthquake does not mean the fault line caused it. It may mean the earthquake is opening up a new old wound because of internal machinations deep in the molten core directly under that old wound. That is a long way from being causal. Earthquakes cause fault lines, yet most geologists hold that fault lines cause earthquakes. Let us ponder this. The September 4 earthquake happened 12kms underground. Current geology wants us to believe that a mighty loose cannon of a 650 kiloton ball of energy, from 12kms away, hurtling surfacewards like a cyclonic wind through solid ground, has some sort of steering mechanism that seeks out old fault lines to surface through. Imagine an H-bomb the size of that which destroyed Hiroshima, heading towards Christchurch from 12kms below. Now imagine 43 such bombs in one explosive package of energy and you have the size of the September 4 earthquake. Would the bomb that struck Hiroshima have had time to seek out the best skyward path to the city, or did it just drop anyway? After falling from the plane, did it wander around in the sky until it found a sky-hole corridor through the air down to the city that some previous (unknown) bomb had created? I cannot see that a 650 kiloton monster earthquake would have bothered to set itself within the confines of a previously carved faultline. Earthquakes go where they choose. If there is a fault line there already, then a shake may shake that too and an observer will say the fault

Faultlines are caused by quakes - not the other way round. line was active. If there is no fault line the earthquake will make one. And scientists now do agree that the 7.1mag earthquake created a new fault line that either they didn’t know was there or that actually wasn’t there. But it cannot both be that earthquakes get caused by old fault lines and at the same time create new cracks in the countryside in totally different places to those previously formed. One other thing. Tectonic plates cannot possibly rub together to cause earthquakes/volcanos. For plates to rub together means they would have to be already separated. Also, heat tends to go up, not down. The answers are upwards, at colossal movements in the heavens that cause tides deep within the earth. Why else would the Te Anau earthquake have been on new moon/closest perigee, the Christchurch 7.1mag.on new moon+second closest perigee, the Napier earthquake on full moon/fourth closest perigee etc etc? These give the clue that earthquakes are tidal, and tied to the moon, not to tectonic plates colliding. There is a tide within the earth that brings earthquakes, eruptions and volcanos at particular times, and these times

coincide with what other known tides are doing. The answers are not looking down at the drums, the horses there have all bolted, so putting new drums on existing fault lines and/or analysing core samples from old faults from the Alps is a waste of time and money. My suggestion to all the geologists, seismologists and other earthquake specialists is forget fault lines, they will lead to nothing useful. It is like examining a pool of water to see when the next tsunami will arrive. Developing methods of determining timing will save lives. The last biggest jolt in Christchurch (5.1 mag) was on 20 January, the day of January full moon and kingtide. The 6.3-mag was two days after full-moon-perigee. The next earthquake risk period is probably in a month’s time, at the next full moon/kingtide in both land and ocean, around 19-21 March. Just as Christchurch needs to be rebuilt old theories need to be reworked. Tectonic plates are about 6-10kms thick under the sea and up to only 10 times that under the continents. Yet some earthquakes occur at a depth of 300kms, a long way from these “colliding” plates. Funny that.
