Primary Nutrients
Nitrogen: One of the major nutrients essential for crops to achieve maximum yields and growth. Nitrogen is vital for chlorophyll production and protein synethesis. Thus it is often required in the greatest quantity.

Phosphorous: Essential for the general health of all plants. Phosphorous plays a key role in several plant structure compounds and vital biochemical reactions in plants such as ATP for photosynthesis and the structure of the plant’s DNA. Growth factors that benefit from this nutrient include improved root development, stronger stalk and stem’s, improvements in crop quality and increased resistance to plant diseases. Phosphorous is fundamental to the successful development of all crops.

Our phosphate based fertilizers includes standard, technical and food grades of nutrients and an extensive range of co-formulants that ensure highly efficient nutrient uptake, longevity and safe use ideal for fertigation, foliar application, and suitable for fertilizer blends and solubles. As fully water soluble fertilizers, they are highly efficient sources of phosphorous. Phosphorous sources have a wide usage including industrial, food, pharma and flame retardant application.
Potassium: In order to sustain plant growth and reproduction, Potassium is essential. It helps regulate plants water content and expansion. Plants deficient in potassium will be more susceptible to disease and is vital to maintain quality and increase crop yields.

We offer a variety of different potassium based products to meet your needs. Whether your application is for fertilization in glasshouses or for outdoor crops, these products are key to achieve good yield and quality in crops and critical to increase the size, juice content and sweetness of fruit. Crops sensitive to chlorine would ideally benefit from the chlorine free, water-soluble and neutral salt nature of soluble SOP. Additionally, we offer granular and standard grade optimal for bulk blending with other fertilizers, as raw materials for compound fertilizers as well as for direct application.
Secondary Nutrients: Three secondary nutrients needed at lower levels.
Calcium: Calcium im proves the uptake of other nutrients by roots, is needed to strengthen cell walls and helps to reduce bruising and disease which results in a longer shelf life and less damage.

These calcium products are ideal for fertilization and foliar application because of their free flowing granularity, high purity and water solubility. As its non-volatile nitrate nitrogen and soluble calcium composition results in the enhanced uptake of other nutrients and improved soil conditions.
Magnesium: This secondary nutrient is necessary for its role in chlorophyll, responsible for photosynthesis. It also aids in cell division, protein formation and various enzyme systems that support plant growth.

Our Sulphur products with their various available grades provide sulphur nutrition gradually throughout the growth period of the plant minimizing leaching and wastage.
Micronutrients: Micronutrients are vital for balanced crop nutrition and plant growth. This includes Boron (B), Copper (Cu), Iron (Fe,), Manganese (Mn), Molybdenum (Mo), Zinc (Zn), Nickel (Ni) and Chloride (Ci).
Whilst plants require greater quantities of primary and secondary nutrients, micronutrients are equally as vital to plant nutrition. Even when there are adequate amounts of other nutrients are available, a lack of any micro-nutrient can limit growth and reduce crop yields. We can offer various micro-nutrient fertilizers including a wide range of single-compound fertilizers containing micro-elements chelated with EDTA chelate,both liquid and solid form. Their free flowing, dust and caking free nature makes these chelates very efficient in providing micro-elements in a form available to plants thus sustaining the root and leaf uptake for longer.
