Humic acid is a natural organic fertilizer with a variety of beneficial effects and effects on plant growth, which are described in detail below:

Improve soil structure. Humic acid can react with clay minerals in soil to form organic-inorganic complex, increase the soil’s aggregate structure and permeability, make the soil more soft and breathable, and facilitate the growth of plant roots and nutrient absorption.
Improve soil fertility and water retention. Humic acid can promote the decomposition and transformation of organic matter in soil, improve soil fertility and water retention capacity, and provide nutrients required by plants, such as nitrogen, phosphorus, potassium and so on.
Enhance plant stress resistance. Humic acid can improve the ability of drought resistance, cold resistance and disease resistance of plants, enhance the immunity of plants, and reduce the occurrence of diseases and pests.
Improve the quality of agricultural products. Humic acid can promote the absorption and utilization of nutrient elements by plants, improve the color and taste of fruits, and enhance the quality and market competitiveness of agricultural products.
Reduce environmental pollution. Humic acid, as a natural organic substance, will not pollute the environment after use, and is more environmentally friendly and sustainable than chemical fertilizers.
In addition, humic acid can also activate the soil, decompose harmful impurities, and restore the soil’s aggregate structure.
