Zeiz MKP is a highly pure fertiliser which dissolves rapidly and completely. As a nitrogen-free fertiliser, Zeiz MKP is the favoured source of phosphorus and potassium when nitrogen fertilisation should be restricted. For example, early in the growing season, when phosphorus and potassium are required at high rates for the establishment of root system. This product can be implemented in combination with other fertilisers to meet crop nutritional demand all along the growth cycle.
