(1) Directly participate in plant metabolism. Plants can directly absorb simple sugars, amino acids, humic acids and other organic substances, which are directly involved in the internal transformation, metabolism, synthesis and other biochemical processes of plants.
(2) Improve the effectiveness of mineral elements and fertilizer utilization rate. The large amount of organic acids in humic acid, etc., makes the insoluble mineral nutrients in the soil turn soluble, which is conducive to the affinity with lipophilicity and cell membrane, and improves the effectiveness of mineral nutrient elements.
(3) Improve crop resistance. Water-soluble polysaccharides in humic acid can regulate the concentration of plant cytoplasm, lower the freezing point to make plants resistant to cold, alkaloids and acids resist or kill pathogenic bacteria and harmful insects to enhance plant resistance to diseases and insects.
(4) Activate and increase beneficial soil microorganisms. Humic acid provides sufficient nutrients for soil microorganisms and increases the population and number of soil microorganisms.
(5) Improving soil physical and chemical properties. The active organic matter and soil minerals in humic acid form organic colloids, which promote the formation of soil agglomerate structure and can improve soil water, fertilizer, gas and heat conditions in general.
As can be seen, it has the advantage of being very rich in organic matter, humus and many kinds of nutrients needed by plant search. Organic fertilizer it can improve the soil and improve the heavy metals in the soil, it can improve the structure of the soil, improve the nutrient elements of the soil, enhance the fertilizer and water retention capacity of the soil, regulate the pH of the soil, promote the activity of soil microorganisms, improve the effectiveness of soil nutrients, etc. It has good effects.
