Potassium humate function and Effect
Potassium humate is a non-uniform aromatic hydroxycarboxylate with a black granule or powdery solid. It is a product obtained by finely selecting lignite and then extracting it with KOH liquid. It is soluble in water and alkaline. It contains an active group such as a carboxyl group or a phenolic hydroxyl group.
The humic acid functional group in potassium humate can absorb potassium ions, prevent water loss in sandy soil and leaching soil, and prevent potassium from sticking in sticky soil. It is 87%–95% higher than the ordinary potassium fertilizer utilization rate. The potassium humate has the combination of land use and soil conservation; long-acting and quick-acting coordination; water retention and fertilizer-retaining effects are obvious. Potassium humate can also pass physical, Chemical biotechnology means to regulate the release rate and achieve two-way regulation of sustained release and sustained release. The balance between the supply of nutrients in the fertilizer and the demand for nutrients in the crop is basically synchronized to achieve a dynamic balance.
1) Potassium humate can improve soil physical characteristics, improve soil aggregate structure, reduce soil compaction, and achieve good conditions;
2) Increasing the cation exchange capacity and fertilizer retention capacity of the soil to adsorb and exchange plant nutrients, improve the slow-acting effect of fertilizers, and increase the ability of soil to maintain fertilizer and water retention;
3) providing activities of soil beneficial microorganisms;
4) Promote the decomposition of artificial (such as pesticides) or natural toxic substances and effects;
5) increase the soil’s ability to balance and neutralize the soil pH;
6) Color black helps to absorb heat and plant in early spring;
7) directly affecting cell metabolism, improving the respiration and photosynthesis of crops, and enhancing the resilience of crops, such as drought resistance, cold resistance, disease resistance, etc.;
8) the nutrients required to release the plants after decomposition;
9) Strong roots increase yield, improve crop quality and increase sweetness.
