Dr. Hugh Poole, international agricultural consultant, said coconut coir is initially high in sodium, potassium and chloride salts. “Where the coconut coir originates from can have an impact on the salt levels.” He further states, “If the EC (electrical conductivity) level is below 1.0 milliSiemens (measure of electric conductance) per centimeter (mS/cm), growers should not have to leach the coir. In most cases, the coir producers have already leached the coir for the growers. It should be ready to use. If the salts level is high, then the coir producer has not done its job. A producer should be able to provide growers with the coir’s EC value, its pH value and other information, including percent moisture, as well.”
