Soiltech products

Many field crops, as well as field vegetables, will benefit from calcium during the growth phase. Optima Vigor+ contains a high concentration of calcium combined with nitrogen, magnesium, manganese and trace elements that are organically complexed. Leaf quality is improved and photosynthesis is optimised.

Optima Leaf-K is a direct available potassium foliar fertiliser. Problems with potassium uptake are often related to the pH value of the soil. A high pH inhibits potassium uptake by the roots. And in drought conditions, potassium is not released into the soil, which prevents it from being absorbed. Foliar fertilisation using Optima Leaf-K offers a solution by supplying this important nutrient to the crop.

Optima Leaf-MnZn+ is a liquid foliar fertiliser based on manganese and zinc that has been 100% organically complexed. In many cases manganese and zinc are sufficiently present, but their uptake by the plants is often impossible. In such cases, only foliar treatment is effective. Manganese and zinc play an important role in keeping the crop green, and therefore in ensuring optimum yields.

Optima Leaf-NPK vital is a liquid NPK leaf fertiliser (6-20-5), high in phosphorus content and enriched with amino acids. The nutrients in Optima Leaf-NPK vital stimulate crop growth, therewith increasing yield and quality.

Optima Leaf-Trace is a liquid foliar fertiliser based on six important trace elements. It contains iron, manganese, zinc and copper that are 100% organically complexed. The product is also enriched with boron and molybdenum.

Optima Leaf-KS is an easy-to-use potassium / sulphur foliar fertiliser specially formulated for immediate and efficient uptake. It contains different forms of potassium, sulphur and a biodegradable effluent to make uptake even more efficient. A foliar fertilisation with Optima Leaf-KS supports crucial processes in the plant, giving better yields with better quality.

Optima Root is a special combination of nutrients, various biostimulants and trace elements that stimulate root growth and shoot development.

Optima Leaf NPK+ is a liquid NPK leaf fertiliser (8-17-9) enriched with trace elements, amino acids, fulvic acids and seaweed extract. The nutrients in Optima Leaf NPK+ improve growth and reduce susceptibility to abiotic stress.

Optima Leaf-Cu+ is a liquid foliar fertiliser based on copper that has been 100% complexed with hepta gluconic acid (HGA). Copper strengthens cells and has a positive effect on sugar and starch production.

Optima Leaf-Mn+ is a liquid foliar-fertiliser based on manganese that has been 100% complexed with hepta gluconic acid (HGA). Manganese deficiency is often common at high pH levels in the soil. Treating the soil with manganese is not effective in this case. There is often sufficient manganese, but its uptake is impossible. In this case, the only effective treatment is foliar treatment. Manganese is an important trace element that is essential for the formation of chloroplasts.
