Soil improvement<\/span><\/h2>\n<p>Humic acid is a porous substance. Which can improve the aggregate structure of soil. Adjust the water, fertilizer, air and heat conditions of soil, improve the soil exchange capacity. Adjust the PH of soil. Achieve the acid-base balance.<\/p>\n<p>Its adsorption and complexation reaction can reduce the harmful substances in the soil (including pesticide residues, heavy metals and other toxic substances). Enhance the natural purification ability of the soil. Reduce pollution. Meanwhile, due to the colloidal properties of humic acid, the microbial community in soil can be improved. Which is suitable for the growth and reproduction of beneficial bacteria.<\/p>\n<h2><span style=\"font-size: 12pt;\">2.
