Humic acid is a kind of natural organic macromolecular compound with a relatively high molecular weight. It appears yellow to black and has fatty and aromatic properties. It is a special organic substance formed by plants through long-term decomposition and transformation under the action of microorganisms, and it holds an important position in the soil.
The sources of humic acid can be traced back to two major categories:
Soil humic acid: Through the action of microorganisms, plants convert it into this large-molecule organic compound.
Coal humic acid: It is extracted from plant residues through long-term geochemical processes.
Humic acid organic fertilizer vs. farmyard manure:
The most significant difference between humic acid organic fertilizer and traditional farmyard manure lies in that humic acid organic fertilizer is rich in nutrients and can be directly absorbed by crops, showing quick effects and having a high utilization rate. However, farmyard manure needs to go through a long-term transformation process before releasing humic acid, and its application effect is relatively slow. Humic acid organic fertilizer helps crops quickly obtain the necessary nutrients, promotes crop growth, and has a better improvement effect on soil structure and the environment.
Summary:
Humic acid can not only improve soil quality but also enhance various indicators of crop growth. It can effectively improve the physical and chemical properties of the soil, increase the soil's water and fertilizer retention capacity, promote the growth of crop roots, enhance stress resistance, and increase crop yield and quality. For agricultural producers, humic acid is undoubtedly an essential quality product for increasing yields and optimizing fertilizer application!
