Humic acid is the remains of animals and plants, Humic Acid mainly the remains of plants, through the decomposition and transformation of microorganisms, Humic Acid as well as a series of complex processes of the Earth's chemical reactions and the accumulation of a class of organic substances. It is composed of aromatic group and its many functional groups of organic acids, with good physiological activity and absorption, complexation, Humic Acid Exchange and other functions. The main elements of humic acid consist of carbon, hydrogen, oxygen, nitrogen and sulphur, which is a kind of poly-valent phenolic aromatic compound and nitrogen compound.
It is widely distributed in low grade coal, soil, water sediments, Humic Acid animal manure, organic manure, plant and animal residues, etc. The soil we often see is blackened, it is the highest humic acid content (30~80%) in low grade coal (weathered coal, lignite, peat), followed by organic compost (about 5~20%), because it contains humic acid (the soil with less humic acid is yellow). The regeneration of humic acid can be formed by artificial oxidation (e.g., by air, ozone or nitric acid).
According to the solubility and color classification in solvents, Humic Acid it can be divided into three components: ① soluble in acetone or ethanol is called brown humic acid; ② insoluble in acetone is called black humic acid; the part of ③ soluble in water or dilute acid is called fulvic acid used in agriculture as nutrient soil additive, rooting and strong root fertilizer additive, soil amelioration agent, Humic Acid plant growth regulator, foliar fertilizer compound agent, cold-resistant agent, drought-resistant agent, compound fertilizer synergist, and so on, with nitrogen, phosphorus, potassium and other elements of humic acid fertilizer, Humic Acid with fertilizer efficiency, improved soil, Stimulate the growth of crops, improve the quality of agricultural products and other functions. Humic acid magnesium, Humic Acid humic acid zinc, the humic acid urea iron has the good effect on the soil magnesium deficiency, the maize zinc deficiency and the fruit tree iron deficiency, which can improve the efficacy and inhibit the residues, and the humic acid sodium is effective in the treatment of apple tree rot disease.
Broad-spectrum plant growth regulators, which promote the development of plants in particular, can properly control the opening of Leaf stomata, reduce transpiration and play an important role in drought resistance, can improve the resilience, increase production and improve quality, Humic Acid the main applications of wheat, Humic Acid corn, sweet potatoes, millet, rice, cotton, peanuts, rape, tobacco, mulberry, fruits, vegetables, etc., and some of the non-alkaline pesticides mixed, and often synergistic synergism.
Low chlorine ions in sulfur-based compound fertilizer, Humic Acid the national standard is less than 3%, and contains a large number of sulfur elements, can effectively improve the soil sulfur deficiency symptoms; chlorine-based compound fertilizer contains a large number of chlorine elements, which has adverse effects on some crops. Urea (n-amide nitrogen) urea in the soil through the soil microbial secretion of urease effect, hydrolysis into ammonium carbonate or ammonium bicarbonate when the water is appropriate, the higher the temperature, the faster the hydrolysis is conveyed to ammonium carbonate, the faster the fertilizer efficiency is, the more rapid, Humic Acid ammonium carbonate is very unstable, Therefore, when applying the compound fertilizer, the soil should be covered to prevent the loss of nitrogen.
The chloride ion content in the sulfur based compound fertilizer is very low, the chlorine ions are removed during the production process, and chlorine ions are not removed in the production process, Humic Acid which is harmful to the chlorine-repellent crops. Therefore, the product contains a large number of chlorine elements; in the process of production, the urea-made molten urine or the molten urine of the solid urea heating is prepared into slurry with potassium chloride or potassium sulfate.
