The function of organic fertilizer
2. Increase production and improve quality. There are rich organic matters and various nutrient elements i organic fertilizer, which provide nutrients for crops. After the decomposition of organic manure, it provides energy and nutrients for soil microbial activities, it promotes microbial activity, accelerates decomposition of organic matter, and produces active substances, etc., which can promote the growth of crops and improve the quality of agricultural products.
3.Improve the utilization rate of fertilizer. Organic fertilizer contains many nutrients, but its low relative content, and its release slowly. However, the nutrient content of chemical fertilizer is high, little composition, and its release fast. Spreading two kinds of fertilizer reasonable with the application, complement each other, the organic acids decomposed by organic matter can also promote the mineral nutrient dissolution in soil and chemical fertilizers. Organic fertilizer and chemical fertilizer to promote each other, is conducive to crop absorption, improve fertilizer utilization.
