Our fertilizers range from those based on the most widely needed nutrients – Nitrogen (N), Phosphorus (P) and Potassium (K) – to those incorporating growth and quality enhancing nutrients, such as calcium (Ca) and magnesium (Mg), to micronutrients that help prevent or cure deficiencies resulting from particular soil or crop conditions.
If crops lack any of these nutrients, yield and profitability are reduced. That’s why we offer not only a product range that meets all crop nutrition needs, but also crop-specific advice and fertilizer management tools and services.
Nitrogen is essential for healthy plant growth and good yield. Straight nitrogen fertilizers are often the major source of this important nutrient.
Nitrate forms of nitrogen are most swiftly absorbed by crops, which is why they are commonly used when a fast response is needed. In contrast, ammonium- and urea-based fertilizers need to be transformed by microbe activity in the soil before plants can absorb them. Therefore they are more commonly used where a more gradual uptake of nutrients is needed.
In addition to nitrogen fertilizers, we supply various composite fertilizer products. These supply several chemically combined major nutrients, most commonly nitrogen (N), phosphorus (P) and potassium (K). Some also contain secondary and micronutrients. Our NPK products have consistent size and mass, which makes accurate spreading easier.
Blended products – mixtures of straight fertilizers – are also widely available. Our products are often utilized in high-quality blends.
We also supply field-grade calcium nitrate fertilizers for cash crops. These products deliver their 33 percent calcium content throughout the season to ensure high-quality fruit and vegetable production for growers and consumers.
Potassium nitrate can also be a valuable product, for example in late-season applications to fruit. Our potassium nitrate range is of high quality and easy to handle.
"Fertigation" is the combined application of water and nutrients to a crop – a mix of fertilizer and irrigation. It can be adapted to all types of crops, but is most common in cash-crop segments, rather than broad-acre or arable crops.
We have a wide range of fertigation and liquid fertilizers to meet any crop situation. Our full range of essential nutrients can be used in drip irrigation, sprinkler systems or pivot agriculture.
Our fertigation products include high-quality calcium nitrate, potassium nitrate and a full range of micronutrient chelates. They’re used in soil and fertigation applications, and can also be used as a source material for foliar products.
Chelates help overcome many problems associated with metallic ion tie-up in the soil by taking a positively charged metallic ion and turning it into a negative form that is less readily rendered unavailable in the soil.
They do so by “sealing” the nutrient in a protective structure that keeps it within the soil solution, effectively preventing nutrient loss.
Our chelated products – devised by our partner Akzo Nobel – are produced from high-grade metals and suited to specific soil and crop situations.
Foliar applications are used for targeted input at the crop’s key growth stages. By spraying directly onto the crop, nutrient availability can be controlled and soil interaction avoided.
Foliar sprays are particularly useful for accurately applying relatively low doses of micronutrients. However major and secondary nutrients are sprayed at key growth stages to supplement soil-applied nutrients, for example calcium sprays on apples during fruit development.
Foliar products need to be correctly formulated, so as to maximize effect and minimize the risk of damage when sprayed onto leaves or fruit.
We utilize suspension concentrates, solutions and powders, which provide controlled nutrient release over a longer period than unformulated products.
We also provide pure, often food- or pharmaceutical grades of nutrients and a wide range of co-formulants that ensure safe use and highly efficient nutrient uptake, biological activity and longevity.
They are also formulated with stickers, spreaders and absorption agents that maximize efficacy and crop safety, thereby prolonging balanced growth.
