Long-term use of potassium sulphate should be used together with the manure, alkaline phosphate and lime with lower acidity, and in practice should be combined with the drainage bask in field measures to improve ventilation.
In calcareous soils, we should pay attention to use more farmyard manure.

Potassium sulphate should not be touched with seeds and roots directly. It can be single use, but also can be used together with other single element fertilizer.
