Organic fertilizer and compound fertilizer

Organic fertilizer and compound fertilizer

Answer:

Both compound fertilizer and organic fertilizer have their own advantages and disadvantages. Only organic fertilizer can be used in conjunction with chemical fertilizers to combine the advantages of organic fertilizers and inorganic fertilizers, while overcoming the shortcomings of organic fertilizers and compound fertilizers.
Organic fertilizer organic fertilizer: mainly refers to a variety of animals and plants, after a period of fermentation and decomposition of the formation of fertilizers (including processed rapeseed cake, there is no smell). Organic fertilizer contains a large number of biological substances, animal and plant residues, excreta, biological waste and other substances, the application of organic fertilizer can not only provide comprehensive nutrition for crops, and fertilizer effect, can increase and update soil organic matter, promote microbial reproduction, improve soil physical and chemical Nature and biological activity, is the main nutrient source for green food production. Composting with a variety of orange straw, leaves, grass, animal and plant residues, human and animal manure as raw material, mixed with a small amount of soil and an organic fertilizer. Composting composting raw materials and composting is basically the same, but in the flooding conditions for fermentation. Manure refers to the pig manure, cattle, horses, sheep, chickens, ducks and other livestock and poultry manure and straw dregs made of retting fertilizer. Biogas Fertilizer In sealed biogas digesters, organic matter is decomposed to produce byproducts of biogas, including biogas and debris. Green fertilizers are cultivated or wild green plants are used as fertilizers. Such as beans, green beans, beans, sweet grass, Tian Jing, alfalfa, vetch and so on. Non-leguminous green manure with ryegrass, fertilizer radish, small sunflower, full of river red, water hyacinth, water peanuts and so on. Crop Straw Crop Straw is one of the important organic fertilizers. Crop Straw contains the nutrients necessary for the crop N, P, K, Ca, s and so on. Under suitable conditions through the role of soil microorganisms, these elements through the mineralization and then back to the soil, for crop absorption and utilization.
Compound fertilizer is mainly to provide carbon, phosphorus, potassium and other elements, the main advantage is the high nutrient content, fertilizer fast, fat strong, can play a quick effect and improve the role of the product; the disadvantage is generally free of organic matter, can only supply crop nutrients, Improving soil and cultivating soil fertility is less effective. Effective time is short, fertilizer can not be sustained. It is also easy
