Role of potassium humate used in agriculture Improved soil potassium humate is the food of microorganisms In the soil where potassium humate forms agglomerate structure, the activity of microorganisms is strong, the biological activity is high, the nutrient supply is sufficient, the preservation and supply of soil nutrients can be better coordinated, thereby improving soil fertility; The part of […]
The direct effect of humic acid is to promote plant growth and increase crop yield. In addition to the direct effects of humic acid, there are physical, chemical, and biological effects. Physical effect Humic acid improves soil structure; prevents soil cracking and erosion; increases soil water holding capacity, improves cold resistance; makes soil color darker, […]
Potassium humate is a carbon chain molecular structure material with high loading and physiological activity. The leaching characteristics of heavy metal copper in contaminated soil by potassium humate, the leaching effect of potassium humate on soil and crops, and the desorption kinetics of copper in soil under the action of potassium humate and the form […]
Soil problems have caught everyone’s attention. The State Council issued a notice on the action plan for soil pollution prevention and control, as well as a draft law on soil control, which has been submitted to the National People’s Congress for approval. All of this shows that the country has begun to pay great attention […]
Biological Activity Mechanism The main elemental composition of humic acid is carbon, hydrogen, oxygen, nitrogen, and sulfur. It is a polycondensate of a polyvalent phenolic aromatic compound and a nitrogen compound. The molecular weight distribution is wide, the molecular weight of small molecules is tens of thousands, and the molecular weight of macromolecules is tens […]
The acidic humic acid has a carboxyl group and a phenolic hydroxyl group in the molecular structure to make it weakly acidic. Therefore, humic acid can be quantitatively reacted with carbonates, acetates, and the like. A buffer solution consisting of humic acid and its salts can regulate the pH of the soil and allow the […]
