EFFECT OF CHLORIDE CONCENTRATION ON CROP GROWTH
This study was based on the dynamics of chloride in soil water system with the use of Murate of Potash (MOP). Fertilizer MOP was applied in the field where wheat was sown as test crop to determine the chloride. Chloride Cl-was absorbed at 100 cm depth after irrigation and rainfall. The result showed that sufficient amount of Cl-is essential for crop growth. Furthermore, Cl-in MOP does not raise any adverse effect to the crop when it accumulates in the soil.
