Used in soil, it can improve soil aeration, enhance soil aggregate structure, and create a favorable environment for root growth. For plants, the small-molecule fulvic acid in this product can be directly absorbed, stimulating crop growth and enhancing the efficiency of leaf photosynthesis. The adsorption and chelation capacity of humic acid helps plants better utilize mineral nutrients in the soil. Humic acid can also increase the soil's cation exchange capacity, improve soil fertility, and enhance fertilizer nutrient uptake efficiency.
