Potassium Humate

Basic Product Description

Potassium Humate is a small-molecule organic potassium fertilizer extracted and refined from weathered coal and lignite. It is rich in active groups including humic acid, fulvic acid, available potassium, amino acids, organic matter, phenolic hydroxyl groups and carboxyl groups. It boasts excellent water solubility and can be applied through foliar spraying, flushing fertilization, drip irrigation, soil mixing and seed dressing. It integrates three functions of organic fertilizer, potassium fertilizer and biostimulant. It is widely applied to field crops, fruits and vegetables, cash crops, seedlings and Chinese medicinal herbs, and can also be added in small doses to livestock and aquafeed.

II. Core Nutritional and Physical-Chemical Advantages

Supplies both organic matter and quick-acting potassium for dual nutrition supplementation

It simultaneously delivers highly active organic carbon and ionic quick-acting potassium, improving soil while supplementing potassium, which distinguishes it from simple inorganic potassium fertilizers such as potassium sulfate and potassium chloride. The potassium ions chelated by humic acid are hardly fixed by soil, greatly boosting nutrient absorption efficiency.

Activates fixed nitrogen, phosphorus and potassium in soil to release insoluble phosphorus and potassium

Functional groups of humic acid can chelate immobilized phosphorus, potassium, calcium, magnesium and trace elements in soil, converting unavailable mineral nutrients into plant-absorbable forms. It significantly raises the utilization rate of chemical fertilizers and cuts the dosage of compound fertilizers.

Improves soil aggregate structure and eliminates soil compaction

It facilitates the formation of soil crumb structure, loosens heavy clay soil and ameliorates saline-alkali land. It enhances the soil’s capacity to retain water and nutrients, reduces water and fertilizer loss, and alleviates soil salinization and acidification in greenhouses.

Regulates soil pH and reduces salt and alkali hazards

Equipped with a weak acid buffer system, it neutralizes soil salinity and alkalinity, lowers salt content on topsoil, and solves problems of poor seed germination and root burn in saline-alkali land.
