Humic acid is a form of natural organic soluble polymer mixture with weak acidity.  It contains carboxylic-, phenolic-OH, quinone and other organic functional groups with biological activity. It has very special physical and chemical properties and special biological activities. An acid derived from humus developed in Dacheng can work as biostimulant and can work together with agrochemical formulations like Glyphosate. It can save up to 50% Glyphosate usage. The application of humic acid with other active ingredient is in research by Dacheng R&D team. This acid can suit farming environment better and have better effect than fulvic acid.
