Carbonaceous material derived from plants or animals and applied to soil to provide plant nutrition as its main function.It is processed from biological substances,animal and plant wastes and plant residues to eliminate toxic and harmful substances.
It is rich in a large number of beneficial substances,including a variety of organic acids,peptides and rich nutritional elements including nitrogen,phosphorus and potassium. It can not only provide comprehensive nutrition for crops,but also has long fertilizer efficiency.It can increase and renew soil organic matter,promote microbial reproduction,and improve soil physical and chemical properties and biological activities.It is the main nutrient for green food production.
Organic fertilizer,commonly known as farmyard fertilizer,refers to slow-release fertilizer containing a large amount of biological substances,animal and plant residues,excreta, biological waste and other substances.Organic fertilizer not only contains a large number of elements and trace elements necessary for plants,but also contains rich organic nutrients.Organic fertilizer is the most comprehensive fertilizer.
The role of organic fertilizer in agricultural production is mainly reflected in the following aspects:
Advantage 1: Improve soil and fertility
After organic fertilizer is applied to the soil,organic matter can effectively improve the physical and chemical status and biological characteristics of the soil,mature the soil,enhance the soil’s ability to maintain and supply fertilizer and buffer,and create good soil conditions for crop growth.
Advantage 2: Increase output and improve quality
Organic fertilizer is rich in organic matter and various nutritional elements to provide nutrition for crops.After the decomposition of organic fertilizer,it can provide energy and nutrients for soil microbial activities,promote microbial activities,accelerate the decomposition of organic matter,and produce active substances that can promote the growth of crops and improve the quality of agricultural products.
Advantage 3: Improve the utilization rate of fertilizer
Organic fertilizer contains more nutrients,but the relative content is low and the release is slow,while chemical fertilizer has high nutrient content, less components and fast release.The organic acids produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and chemical fertilizer.Organic fertilizer and chemical fertilizer promote each other,which is conducive to crop absorption and improve the utilization rate of fertilizer.
