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.
While sulfur is the fourth major nutrient and is required for synthesis of the essential amino acids and proteins. It can enhance crop stress resistance and promote other nutrients absorption.
Potassium source like Potassium Chloride (KCI) is highly soluble in water. It can be easily get lost in the field via leaching and run-off in pores soil like pet soil and sandy soil especially in high rainfall area.
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.
Absorb Moisture → Disolve → Release
Application Rate for Oil Palm
HARACOAT SCK use rate is 30% less than normal KCI. If normal KCI use rate is 2.5kg/palm/application for mature oil palm, HARACOAT SCK use rate will be 1.75kg/palm/application, broadcast along the staking row.
