1. Potassium is one of the three major nutrients; it can improve crop quality, promote protein synthesis, enhance crop resistance to pests and diseases, prevent lodging and increase oil yield for oil producing crop. 2. While sulfur is the fourth major nutrient and is required for synthesis of essential amino acids and proteins. It can enhance crop stress resistance and promote other nutrients absorption. 3. Potassium source like Potassium Chloride (KCl) is highly soluble in water. It can be easily get loss in the field via leaching and run-off in pores soil like peat soil and sandy soil especially in high rainfall area. 4. HARACOAT SCK is a controlled release potassium, made by coating granular potassium with sulfur and polymer. This unique controlled release characteristic provides continues supply of potassium and also sulfur to meet the plant demand. 50kg plastic bag with 60micron inner
