Five functions of organic fertilizer

Organic fertilizer, commonly known as farmyard fertilizer, refers to slow-acting fertilizers that contain large amounts of biological matter, animal and plant residues, excreta, and biological waste. Organic fertilizer not only contains a large number of elements and trace elements necessary for plants, but also contains abundant organic nutrients. Organic fertilizer is the most comprehensive fertilizer. The role of organic fertilizers in agricultural production is mainly manifested in the following aspects:

First, improve the soil, fertility fertilization organic fertilizer applied to the soil, organic matter can effectively improve soil physical and chemical status and biological characteristics, mature soil, enhance soil fertility and fertilizer supply capacity and buffer capacity, create a good soil for the growth of the crop condition.

Second, increase production, improve quality Organic fertilizer contains a wealth of organic matter and various nutrients, providing nutrition for crops. After decomposing organic fertilizers, it provides energy and nutrients for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that can promote the growth of crops and improve the quality of agricultural products.

Third, improve the utilization of fertilizers Organic fertilizer contains many nutrients but the relative content is low, the release is slow, while the fertilizer unit nutrient content is high, the composition is less, release faster. The two are applied rationally and complement each other, and organic acids produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and chemical fertilizers. Organic fertilizer and chemical fertilizer promote each other, which is conducive to crop absorption and increase fertilizer utilization.

Fourth, improve the ability of drought resistance and resistance to organic fertilizer applied to the soil, can enhance the soil water storage capacity, under drought conditions, can increase the drought resistance of the crop. After applying the organic fertilizer, it can also increase the degree of interstitiality of the soil, loosen the soil, improve the ecological environment of the root system, promote the development of the root system, and improve the ability of the crop to bear maggots.

V. Reducing environmental pollution Organic waste contains a large number of pathogenic eggs. Failure to timely dispose of pathogenic bacteria can increase the concentration of ammonia, nitrate, and soluble organic nitrogen in groundwater, and eutrophication of surface and groundwater, resulting in environmental quality. Worsening, even endangering the survival of living things. Therefore, the rational use of these organic fertilizers can reduce environmental pollution.
