Humic acid fertilizer is a new type of fertilizer containing humic substances based. The fertilizer improve soil fertility and improve soil. Humic acid is an organic colloid, dark brown, great inner surface and colloid surface area, strong adsorption, soil building, improve soil aggregate structure, enhance the role of crop yields; improve fertilizer. First humic acid is a chelated organic acids, adsorption, exchange and activation of the soil in a variety of mineral elements, such as phosphorus, potassium, calcium, magnesium, etc., so that it greatly increased the effectiveness, thereby enhancing its fertilizer. Followed by humic acid fertilizer has a long-acting effect. Humic acid with nitrogen can reduce nitrogen instant, make it slow release fertilizer, while reducing ammonia volatilization loss of nitrogen fertilizer, thereby improving the utilization of nitrogen fertilizer. Humic acid and potash, potassium ions can be reduced with water wastage and improve its utilization cited; having crops stimulation. Can promote crop root growth, and enhance the absorption of nutritional elements, so as to improve crop yields; improve crop resistance to disease.
