| Introduction | humic acid is a mixture of natural organic macromolecular compounds. It widely exists in nature, and the proportion of humic acid in soil is the largest. Soil humic acid is a heterogeneous and complex mixture of physical chemistry, organic polyelectrolyte compositions of relatively high molecular weight, yellow to black, amorphous, colloidal, fatty and aromatic nature cannot be represented by a single chemical structural formula. |
| type | humic acid commonly used as fertilizer is divided into lignite humic acid, weathered coal humic acid, Peat (Caotan humic acid). |
| function | humic acid can promote plant growth and improve crop yield; Humic acid is a friend of inorganic fertilizer, it is the slow-release agent and stabilizer of nitrogen fertilizer, THE SYNERGIST of phosphate fertilizer, the protective agent of potassium fertilizer, the regulator and chelating agent of medium and trace elements. Humic acid has a significant synergistic effect on chemical fertilizer, is the world's chemical fertilizer in the peak of Qomolangma. |
