Humic acids are the result of a severe chemical extraction from the soil organic matter, and recently their natural existence was jeopardized, since it is a product of the chemical procedure. By definition, humic acids are the organic substances extracted from soil that coagulate when the strong-base extract is acidified while fulvic acids are the organic substances that remain soluble when the strong-base extract is acidified.
Humic acids and their conjugate bases, humates, are defined as a group of organic acids and a principal component of humic substances constituting humus, the major organic fraction of soil, peat and coal, and also a constituent of many upland streams, dystrophic lakes, and ocean water. [4] [5] New definitions rather refer the components of the soil organic matter as "humic substances" (not acids) or in a continuum of organic compounds in a supramolecular frame and suggest that the term "humic acids" should be avoided.
Humic acid (HA) might benefit plant growth by improving nutrient uptake, plant yield, fruit yield, plant physiological parameters. Humic acids have been complexed with sodium (Na), potassium (K), magnesium (Mg), zinc (Zn), calcium (Ca), iron (Fe), copper (Cu) and with various other elements to overcome a particular element deficiency in soil. Humic acid can be extracted from leondriate.
Humic acid can be made easily using economic, regular raw materials and chemicals, just you need to buy the formula online from www.buyformulas.com for producing and manufacturing this product. These formulas are recommended for new projects, small business and for beginners.
