It is directly involved in plant metabolism. Plants can directly absorb simple sugars, amino acids, humic acids and other organic compounds, which are directly involved in the transformation, metabolism, synthesis and other biochemical processes in plants.
Improve the availability of mineral elements and fertilizer utilization. A large number of organic acids in humic acid make insoluble mineral nutrients in soil soluble, which is conducive to affinity with lipophilicity and cell membrane, and improve the availability of mineral nutrients.
improve crop resistance. The water-soluble polysaccharide in humic acid can regulate the concentration of plant cytoplasm, reduce the freezing point and make plants cold resistant. Alkaloids and acids can resist or kill pathogenic bacteria and harmful insects and enhance the ability of plant resistance to diseases and insects.
Activate and increase soil beneficial microorganisms. Humic acid provides sufficient nutrition for soil microorganism, and increases the population and quantity of soil microorganism.
Improve soil physical and chemical properties. The active organic matter in humic acid and soil minerals form organic colloid, which promotes the formation of soil aggregate structure, and can comprehensively improve the soil water, fertilizer, gas and heat conditions.
