High CEC Humic Acid Powder 80% Cation Exchange Improver for Sandy Saline Arid Soils

Saudi Arabia, the UAE and the drier parts of Thailand and Indonesia share a specific problem: sand with almost no exchange capacity. Irrigation water, whether from a well or a desalination line, carries sodium and chloride, and with nothing to hold calcium and magnesium the soil structure collapses into a sealed surface layer within two or three seasons. This 80 percent grade is the highest concentration we produce, with a cation exchange capacity measured at 400 to 450 meq
