Potassium fertiliser is commonly used to improve the yield and quality of plants growing in soils that are lacking an adequate supply of this essential nutrient. Concentrations of K in soil are often too low to support healthy plant growth. SOP is but one K option available to amend levels in the soil and can also be used where Potassium Chloride can't.
Potassium is needed to complete many essential functions in plants, such as activating enzyme reactions, synthesizing proteins, forming starch and sugars, and regulating water flow in cells and leaves. Potassium sulphate is an excellent source of nutrition for plants. The K portion of the K2SO4 is no different than other common potash fertilisers, however, it also supplies a valuable source of S which is sometimes deficient for plant growth.
