Answer: what is organic fertilizer?

Some netizens left a message: now there are many brands of organic fertilizer on the market, what is the role of organic fertilizer? In view of the above problems, the farming network has sorted out the characteristics and advantages of organic fertilizer, which are listed in detail below for netizens' reference. Special point 1, organic fertilizer to provide a variety of nutrients for crops: organic fertilizer, also known as farm fertilizer, is a kind of safe fertilizer. It generally contains all kinds of nutrient elements and rich organic matter needed by crops, including nitrogen, phosphorus, potassium, boron, molybdenum, zinc, manganese, copper and other trace elements and growth stimulating hormone. Second, organic fertilizer can improve the efficiency of chemical fertilizer: organic fertilizer reduces nutrient fixation, and the main mechanism to improve the efficiency of chemical fertilizer is the "chelation" of organic fertilizer. The so-called "chelation" forms a ligand between the humic acid in the organic fertilizer and the inorganic salt in the soil, which makes them combine firmly with each other, reduces the chemical reaction between the nutrient elements and the soil, and improves the effectiveness of the fertilizer. improve the utilization rate of chemical fertilizer, avoid chemical loss and pollution, and improve the quality of agricultural products. Various organic acids and carbonic acids produced in the decomposition of organic fertilizers can promote the transformation of insoluble phosphate in soil and improve the availability of phosphorus. Most of the nutrients in organic fertilizers are organic, which must be decomposed by microorganisms and transformed into inorganic states absorbed by crops. This process is slow and gradually transformed to release nutrients. Therefore, organic fertilizer is not only effective in that year, but also has a long stamina, stable but not violent. Third, organic fertilizer can increase the number of soil microorganisms and provide the necessary energy: organic fertilizer is not only the food of crops, but also the food of soil microorganisms. Organic fertilizer contains a large number of microorganisms, most microorganisms rely on the existing organic matter to maintain life, the soil is rich in organic matter, promoting the exuberant activity of microorganisms. In the process of metabolism, microorganisms release a large number of enzymes to produce a black or brown humus, which can provide long-lasting and stable energy to microorganisms and create a good living environment for microorganisms. Special point 4. Organic fertilizer can effectively improve the physical properties of soil: humus is a colloid substance and has water stability. The humic cohesive force of soil is 10.5 times less than that of clay, and that of clay is less than that of sand. Organic fertilizer can improve the water and fertility of sandy soil, reduce its cohesion to clayey soil, make it loose, make use of tillage and drainage, and prolong the suitable tillage period of soil. Humus also deepens the soil color, absorbs heat and increases temperature, which is beneficial to seed germination and crop growth. Humus has a strong ability to absorb water and can generally absorb 9 to 25 times its own weight of water, which contributes to the drought and flood resistance of crops. Special point 5, organic fertilizer can enhance soil fertilizer conservation: organic fertilizer has many functions, its core part is organic colloid, organic colloid has cementation, organic colloid has cementation, and so on. A large number of organic colloids are concentrated in organic fertilizers, which has a strong ion exchange capacity, which is equivalent to 10 to 20 times of the soil, thus greatly increasing the absorption of potassium, sodium, calcium, magnesium, iron and aluminum in the soil. Special point 6, organic fertilizer can reduce soil pollution: the humus of organic fertilizer can absorb some pesticides and chelates formed by organic matter and heavy metal ions, which is easily soluble in water and can be discharged from the soil, which can eliminate pesticide residues and reduce heavy metal pollution.
