Soiltech - Model Optima Leaf-K - Potassium Foliar Fertiliser - Brochure

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.
