Organic fertilizer, mainly derived from plants and/or animals, is applied to the soil to provide plant nutrition as its primary function of carbon-containing materials. By biological substances, animal and plant waste, plant residues processed, eliminated the toxic and harmful substances, rich in a large number of beneficial substances, including: a variety of organic acids, peptides and including nitrogen, phosphorus, potassium, including rich nutrients. Not only can provide comprehensive nutrition for crops, but also long fat efficiency, can increase and update soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, is the main nutrient of green food production.
Organic fertilizer, commonly known as farm fertilizer, refers to slow-acting fertilizer containing a large number of biological substances, animal and plant residues, excreta, biological waste and other substances. Organic fertilizer not only contains a large number of essential elements, trace elements, but also rich in organic nutrients, organic fertilizer is the most comprehensive fertilizer. The role of organic fertilizer in agricultural production is mainly manifested in the following aspects:
First, improve the soil, fertilization. After organic fertilizer is applied to the soil, organic matter can effectively improve soil physical and chemical conditions and biological characteristics, ripen the soil, enhance soil fertility and buffer capacity, and create good soil conditions for crop growth.
Second, increase production, improve quality. Organic fertilizers are rich in organic matter and various nutrients to provide nutrients for crops. After the organic fertilizer is dissolved, it provides energy and nourishment for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that can promote crop growth and improve the quality of agricultural products.
Third, improve the utilization rate of fertilizer. Organic fertilizer contains more nutrients but relatively low content, slow release, and fertilizer unit nutrient content is high, less ingredients, release fast. The two are applied in a reasonable way, complement each other, and the organic acids produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and fertilizer. There is a mutual promotion of fertilizer and fertilizer, which is conducive to crop absorption and improve the utilization rate of fertilizer.
