Sodium humate ——Improve soil, reduce heavy metals and environmental toxicity of soil and crops


Sodium humate is the sodium salt of humic acid and a bioactive substance. In agricultural production, sodium humate  is mainly used to improve soil, reduce heavy metals and environmental toxicity of soil and crops, improve the utilization rate of fertilizer, improve the quality of crops, improve the stress resistance of crops and promote the growth and development of crops. Sodium humate is a kind of with good biological activity. The organic carrier composed of a variety of functional groups is also an intermediate substance with the functions of plant respiration, photosynthesis and metabolism. Therefore, it has great compatibility and can be combined with a variety of substances. Sodium humate and pesticides are mainly combined through the interaction of ion bond, hydrogen bond, proton transfer, electron transfer and complexation to form a new pesticide polymer complex, which is sodium  humate environmental protection pesticide. The combination of sodium humate with insecticides, fungicides and herbicides can enhance the efficacy and reduce the toxicity. The specific performance is——solubilization: sodium humate  can play the role of surfactant, and the surface tension of its metal salt is lower than that of water, which can produce obvious dispersion and emulsification effect on pesticides and improve the solubility of soluble pesticides; Synergism: sodium humate  can enhance the absorption of pesticides by plants, improve the biological activity of pesticides and plant growth regulators, and significantly improve the effect of pesticides. Sodium  humate has slow-release effect. Sodium humate has obvious inhibitory effect on the decomposition rate of pesticides, and the greater the amount of sodium humate, the slower the rate; Sodium humate can inactivate the activities of enzymes sensitive to pesticide toxicity, stimulate the activities of enzymes antagonistic to pesticides, and alleviate and reduce the toxicity of pesticides.

Sodium humate can make ammonium bicarbonate reduce the loss of ammonia nitrogen and improve the utilization rate of nitrogen fertilizer; It can inhibit urinary enzyme activity and reduce urea volatilization; It can inhibit the fixation of water-soluble phosphorus in soil and promote the absorption of phosphorus by roots. Sodium humate chelates with insoluble trace elements, which is conducive to the absorption of trace elements by roots and leaves.

Sodium humate contains a variety of functional groups. The activated sodium humate becomes a highly effective bioactive substance, which can stimulate crop growth and development and physiological metabolism in the body. This characteristic is not possessed by general fertilizers. The activated sodium humate  highly effective bioactive substance adopts the methods of seed soaking, root soaking, root dipping, spraying, watering and base fertilizer according to a certain concentration, It has obvious stimulating effect on all kinds of crops. The comprehensive performance is to promote root development and have a good impact on crop yield and quality factors.
