POTASSIUM HUMATE,obtained from leonardite with high content of humic acid, is a kind of high polymer heterogeneous aromatic potassium salt that contains polyhydroxy, carboxylic acid and other active groups. It’s alkaline, soluble in water and has multiple functions of ion exchange, absorbing, chelating, complexing, flocculating, bonding and so on.
■Benefits
√ Improves the soil structure and the water retention capacity
√ Increases and stimulates beneficial soil microorganisms
√ Enhances the soil cation exchange capacity
√ Decreases stresses due to drought and salinity and/or application of pesticides
√ Increases yield and improve the quality of plants
√ Promotes root development and increases nutrient uptake
√ Increases the effectiveness of fertilizers and less fertilizer consumption
