Applicable to all kinds of soil, sulfur-free soil such as sand and gravel with low air pollution in mountainous areas and low organic matter content, can also supplement its sulfur nutrition;
Long-term application of potassium sulfate in acidic soils may lead to acidification of the soil, and should be applied with lime or other alkaline fertilizers;
Old decayed paddy fields, paddy fields with high organic matter content and high reductivity, are easily reduced to H2S (hydrogen sulfide) in fertilizers, and generally do not use potassium sulfate. Potassium sulfate is suitable for a variety of crops.
For cruciferous crops, onions, alfalfa, garlic, etc., which require more sulfur or avoid chlorine crops, the effect is better.
