Humic acid (Humic Acid, abbreviated HA) is a plant and animal remains, Amino Acid mainly plant remains, through microbial decomposition and transformation, as well as a series of complex geochemical reaction process and accumulated a class of organic matter. It is composed of aromatic and its various functional groups of polymer organic acids, with good physiological activity and absorption, Amino Acid complexation, exchange and other functions. Humic acid is the main element of carbon, hydrogen, oxygen, nitrogen, sulfur, is a polyvalent phenol type aromatic compounds and nitrogen compounds polycondensate.
Widely distributed in low-grade coal, Amino Acid soil, water sediments, animal feces, organic fertilizers, animal and plant residues and so on. We often see the soil is black, that is because the humic acid (not containing, less humic acid is yellow) in low-grade coal (weathering coal, lignite, peat) humic acid content of the highest (30 ~ 80%), followed by organic compost (about 5 to 20%). Coal is artificially oxidized (as treated with air, Amino Acid ozone or nitric acid) to form regenerated humic acid
According to the solubility in the solvent and color classification, Amino Acid can be divided into three components: ① dissolved in acetone or ethanol part called brown acid; ② insoluble in acetone part called black fulvic acid; ③ soluble in water or thin The acid part is called fulvic acid
For the agricultural can be used as nutrient soil additives, rooting and Zhuanggan fertilizer additives, soil conditioner, plant growth regulator, foliar fertilizer compound, Amino Acid cold agent, drought agent, compound fertilizer synergist, and nitrogen, phosphorus, Potassium and other elements combined with humic acid fertilizer, with fertilizer efficiency, improve the soil, stimulate crop growth, improve the quality of agricultural products and other functions. Humic acid and leachate, atrazine and other pesticides mixed with, Amino Acid can improve the efficacy, Inhibition of residual toxicity; sodium humate is effective in the treatment of apple tree rot.
Amino acids in the role of plant growth has three: 1) organic nitrogen nutrient supplement source; 2) metal ion chelating agent. (Calcium, magnesium, iron, manganese, zinc, Amino Acid copper, molybdenum, boron, selenium, etc.) are easily carried into the plant by the action of the complex (chelating) metal ions, and the essential elements and trace elements (calcium, Improve plant utilization of various nutrients; 3) enzyme preparations. Amino acids are the accelerators and catalysts for the synthesis of various enzymes in plants, Amino Acid which play an important role in plant metabolism. However, amino acids in the soil easily assimilated by bacteria, decomposition, it should not be used as a base fertilizer in the soil, but made of foliar fertilizer, spray on the leaves so that plants directly through the leaf absorption of amino acids and other elements.
