Potassium Sulphate is a water-soluble, neutral salt, and has no effect on soil acidity or alkalinity (pH). Potassium and Sulphur are essential elements vital to many functions within the plant. It provides with 50% K2O equivalent, and adequate Sulphur. It can be a very good raw material to produce NPK fertilizer. Our Potassium fertilizer - SOP is free of Chloride Ion and free acid.
Potassium - (K):
Potassium is an immobile nutrient in the soil, moving slowly and for only short distance (by diffusion) through moisture films on soil particle surfaces. It can leach in very sandy or organic soils, but seldom leaches out of the crop root zones.
Nearly every aspect of plant growth is dependent upon an adequate supply of Potassium (K). Potassium helps to improve plants' disease resistance, tolerance to water stress, winter hardiness, tolerance to crop pests, and increased efficiency of (N) use.
Sulphur - (S):
Providing adequate amounts of Potassium in fertilizer to meet current crop needs and to build soil (K) levels is critical to sustain profitable crop production. This essential nutrient is required in greater amounts than any other nutrient except (N) and some crops take up more (K) than (N). Only when the soil is adequately supplied with (K) can optimum crop production be sustained.
