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.
