Organic fertilizer is complex in composition, contains organic matter and various nutrients. It is a complete fertilizer; it has a wide range of sources, many types, large quantities, low cost, and is easy to obtain locally.
Organic fertilizers are bulky, slow in fertilizer efficiency, and low in nutrient content. Therefore, storage and transportation are more labor-intensive and inconvenient to apply. Organic fertilizers contain various nutrients required by plants and organic matter of fertilized soil. Therefore, organic fertilizers not only increase soil nutrients, provide nutrients for plants, but also play an important role in improving soil fertility, improving soil and improving soil ecology. . Organic fertilizers contain a large number of elements and trace elements necessary for plant growth. Most of the nutrients are organic, and after being decomposed by microorganisms, they can be converted into soluble nutrients that can be directly absorbed and utilized by plants.Agricultural probiotics Organic substances in organic fertilizers, such as amino acids, guanamines, soluble sugars and phospholipids, are important sources of plant organic nutrition. Active substances such as humic acid, auxin, and hormones produced during the decomposition of organic fertilizers play an important role in improving plant nutrition, enhancing metabolism, promoting plant root development, stimulating plant growth, and improving plant nutrient utilization. Organic fertilizer is a late-acting fertilizer. It has slow decomposition of nutrients, is not easy to leaching, and has long fertilizer effect. It is not only effective in the current year, but also has a long-term effect. Therefore, it can continuously supply plant mineral nutrients, organic nutrients, and carbon dioxide for a long time. Increasing the content of various nutrients in the soil The application of organic fertilizers can increase the content of various nutrients in the soil. At the same time, organic fertilizer is decomposed by soil microbes, which converts delayed nutrients into quick-acting nutrients, and organic acids and inorganic acids are often produced during the decomposition process, which can promote the dissolution of some insoluble inorganic nutrients in the soil, thereby increasing soil available nutrients. Therefore, the application of organic fertilizers can increase the potential nutrients and available nutrients of the soil.
