People's planting and management methods have been progressing with the advancement of science and technology, but the soil has always been the carrier of planting, so the importance of the soil is obvious, so if you want to grow well, you must ensure that the soil is fertile, and the organic matter in the soil determines the fertility of the soil.
Is organic matter equal to humic acid?
The first thing to know is that organic matter is not equal to humic acid, some experts believe that the content of lignin determines the content of humic acid, and coal chemical scientists believe that weathered coal, peat, etc. contain a large amount of humic acid, and coal humic acid and soil humic acid have similar physical properties, chemical characteristics, molecular structure and molecular weight range, consistent application.
What does humic acid do?
Humic acid is a soil improver, with the improvement of people's living standards and lifestyle changes, more and more farmers do not like to use dirty and smelly farm manure to use. It is bound to destroy the soil structure for a long time, so the importance of humic acid is reflected.
Humic acid can promote the formation of soil aggregate structure, reduce soil bulk density, increase cation substitution, and adjust soil alkalinity, thereby helping to improve the ability of soil to retain water and fertilizer.
And because humic acid is an organic matter of polymers, after entering the soil, it can provide sufficient energy for soil microorganisms, promote the metabolism and reproduction of microorganisms, increase the amount of microorganisms, and enhance the microorganisms of the soil, which is particularly important for improving the soil.
Humic acid is a synergist of fertilizers, nitrogen, phosphorus and potassium fertilizers play a great role in improving the quality of agricultural products, and humic acid can effectively improve the application rate of nitrogen, phosphorus and potassium, thereby solving the cost of fertilization.
