Sulphate of Potash Fertilizer

Sulphate of potash fertilizer is a chemically neutral and physiological acid fertilizer that is suitable for a variety of soils (excluding flooded soil) and crops. After application into the soil, potassium ions can be directly absorbed and utilized by crops and can also be absorbed by soil colloids. It can be used as a base fertilizer. In the dry field, it is necessary to deeply cover the soil to reduce the crystal fixation of potassium, facilitate the absorption of crop roots, and improve the utilization rate.

Sulphate of potash fertilizer is not as good as that of potassium chloride in soils with strong reducibility, such as paddy fields, and its main disadvantage is that hydrogen sulfide toxicity is easy to occur. Potassium sulfate compound fertilizer has better fertilizer efficiency for cruciferous crops with more sulfur, so it can be preferentially distributed.
