Zeiz SOP is a highly pure potassium fertiliser, which dissolves rapidly and completely. This product is not sensitive to caking and is recommended during fruit or tuber development and up until maturation, and during colouring of fruits. The high level of potassium in the formula plays an essential role in achieving higher-quality yields. Zeiz SOP is readily available for plant uptake by providing concentrated nutrition. Also, it enhances the plant’s resistance to drought, frost, insects and diseases, thus improving yield and quality.
