Advantage 1: Improving soil fertility
95% of the trace elements in the soil exist in insoluble form and cannot be absorbed and utilized by plants.
The organic matter in organic fertilizer increases the content of organic matter in soil,reduces the cohesion of soil,and strengthens the water and fertilizer retention performance of sandy soil. Therefore,the soil forms a stable aggregate structure, which can play a good coordinated supply capacity of fertility.If organic fertilizer is used, the soil will become loose and fertile.
Advantage 2:Improve soil quality and promote soil microbial reproduction
Organic fertilizer can make microorganisms in soil multiply,especially many beneficial microorganisms,such as nitrogen fixing bacteria,ammoniating bacteria,cellulose decomposing bacteria and so on.These beneficial microorganisms can decompose organic matter in soil,increase soil aggregate structure and improve soil composition.
Advantage 3:Provide comprehensive nutrition for crops and protect crop roots
Organic fertilizer contains a lot of nutrients, trace elements,sugars and fats needed by plants.
The CO2 released from the decomposition of organic fertilizer can be used as a material for photosynthesis.Organic fertilizer also contains 5% of nitrogen,phosphorus and potassium and 45% of organic matter,which can provide comprehensive nutrition for crops.
Advantage 4:Enhance the ability of crops to resist disease, drought and waterlogging
Organic fertilizer contains vitamins and antibiotics,which can enhance crop resistance and reduce or prevent diseases.The application of organic fertilizer into the soil canenhance the water storage and water retention capacity of the soil,and can enhance the drought resistance of crops in drought conditions.
At the same time,organic fertilizer can also loosen the soil,improve the ecological environment of crop roots,promote root growth,enhance root activity,improve crop waterlogging tolerance,reduce plant mortality and improve the survival rate of agricultural products.
Advantage 5: Improve food safety and green
The state has already expressly stipulated that the excessive use of inorganic fertilizer must be limited in the process of agricultural production,and organic fertilizer is the main fertilizer source for the production of green food.Because various nutrient elements in organic fertilizer are relatively complete,and these substances are completely non-toxic,harmless and pollution-free natural substances,it provides necessary conditions for the production of high-yield, high-quality and pollution-free green food.
Advantage 6: Increase crop yield
Beneficial microorganisms in organic fertilizer use organic matter in soil to produce secondary metabolites,which contain a large number of growth promoting substances.
Advantage 7:Reduce nutrient loss and improve the utilization rate of chemical fertilizer
The actual utilization rate of chemical fertilizer is only 30% ~ 45%. Some of the lost fertilizer is decomposed and released into the atmosphere, some is lost with the water and soil flow, and some is fixed in the soil and cannot be directly absorbed and utilized by plants.
