Why should organic fertilizer be applied?

Why should organic manure be applied to farming? What are the benefits of applying organic fertilizer? What are the effects of organic fertilizer? The following land network is briefly introduced for netizens' reference. 1. Comprehensive nutrients: organic fertilizer is a kind of complete fertilizer, which contains rich carbon, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, silicon and other large and medium elements and a certain amount of iron, copper, zinc, manganese, boron, molybdenum and other trace elements needed for the growth and development of crops. 2. Soil improvement: organic fertilizer contains a lot of organic matter. Long-term application can increase soil organic matter, improve soil aggregate structure, promote soil microbial reproduction, make soil loose and aerated, and facilitate drainage and tillage. 3. Fertilizer and water conservation: the application of organic fertilizer can enhance the fertilizer conservation and buffering capacity of the soil. Humus is an organic colloid with small particles but large surface area. Its water absorption capacity and substitution capacity are more than 100 times and 4 times larger than those of inorganic colloids. Long-term application of organic fertilizer can increase the number of organic and non-body composite colloids, closely integrate the soil, and enhance the capacity of water conservation, fertilizer conservation and fertilizer supply. 4. Promote crop growth: humic acid is the main component of humus in organic fertilizer, which can promote seed germination, root growth and nutrient absorption. The application of organic fertilizer can also increase the concentration of carbon dioxide, an important raw material of photosynthesis, by several times to dozens of times. 5. Improve the utilization rate of fertilizer: the combination of organic fertilizer and chemical fertilizer can help each other, complement each other and promote each other. The acid produced during the decomposition of organic fertilizer can promote the dissolution of mineral nutrients. 6. Improve the quality of agricultural products: organic fertilizer is a necessary food for crops. The nutritional composition and effect of organic fertilizer can not be replaced by other fertilizers, so we should apply more organic fertilizer.
