Humic acid is a type of organic substance produced by microbial decomposition and transformation of animal and plant remains. Humic acid has the ability to fix nitrogen, fix potassium, and decompose phosphate. Therefore, humic acid can promote the absorption of nitrogen, phosphorus, and potassium by crops.
Humic acid itself contains elements needed for plant growth: carbon, hydrogen, oxygen, nitrogen, etc. At the same time, it can improve the utilization rate of nitrogen, phosphorus, and potassium fertilizers. Therefore, humic acid has a very obvious effect on increasing crop yields. Compared with the application of chemical fertilizers, the application of humic acid fertilizers and organic-inorganic compound fertilizers generally increases the yield of field crops by about 8% to 20%, and the yields of fruits, vegetables, and cash crops generally increase by about 15% to 35%.
Potassium Humic Acid Max is a high quality organic fertilizer containing high concentrations of humic acid, fulvic acid and potassium. Humic and fulvic acids are natural compounds found in soil organic matter. They play a vital role in soil and plant health as they help improve soil structure, increase nutrient retention, and enhance plant growth and stress resistance.
Potassium humate is the potassium salt of humic acid, produced by commercial alkali extraction of weathered lignite. It is mainly used as a soil conditioner and in agriculture as a valuable fertilizer additive to increase the efficiency of fertilizers, especially those containing nitrogen and phosphorus.
