Significance of potassium humate in agriculture
Potassium humate is a mixture of natural macromolecular organic compounds that promote crop growth and increase crop yields.
Potassium humate also has physical effects such as improving soil structure, preventing soil cracking and erosion, enhancing soil water holding capacity, improving cold resistance, darkening soil color, and facilitating solar energy absorption.
It has the chemical effects of regulating soil pH, improving and optimizing plant nutrient and water absorption, increasing soil buffer capacity, enriching organic matter and minerals necessary for plant growth, improving the solubility of organic fertilizers, and reducing fertilizer loss; Biological effects such as the growth and reproduction of beneficial microorganisms in the soil, and the ability of plants to naturally resist pests and diseases
In addition, potassium humate also has the function of fertilizing soil. “Soil improvement is a big industry. The soil structure determines many shapes of soil, such as aeration, water retention, and fertilizer retention. Therefore, improving soil traits can effectively improve soil problems. Soil humus is the most important soil organic matter. The composition is homologous with ore source humic acid.
The organic matter entering the soil is converted into humic acid by microbial processing, and the formation of soil aggregate structure can be promoted by using humic acid, so that the soil retains water and keeps fertilizer and breathable.
Many soil problems are caused by the soil aggregate structure. As long as the soil agglomerates are changed, the problems of soil water conservation, fertilizer conservation and salinization are effectively improved.
Potassium humate complexes with nitrogen and phosphorus. A relatively stable complex is formed, and nutrients are slowly released after entering the soil. Compared with common compound fertilizer, the fertilizer efficiency is longer and the nutrient utilization rate is higher.
For example, humic acid and potassium humate complexed with urea to form humic acid urea; and the salt formation reaction can be used to form ammonium humate; and further react to form a carbon-nitrogen bond. The organic matter formed by each chemical reaction can double the utilization of nitrogen.
