There are a lot of farmers on organic fertilizer is not very understanding of the kind, and for the role of fertilizer will listen to those exaggerated rumors, so organic fertilizer in the end in the process of crop production what role? Where is the difference between organic fertilizer and inorganic fertilizer?
After the application of organic fertilizer into the soil, organic matter can effectively improve the physical and chemical condition and biological characteristics of soil, mature the soil, enhance the capacity of maintaining and supplying fertilizer and buffering and create good soil conditions for the growth of crops.
Organic fertilizers are rich in organic matter and various nutritional elements, which provide nutrition for crops. After decomposition of organic fertilizer, it provides energy and nutrients for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that can promote the growth of crops and improve the quality of agricultural products.
Organic fertilizer contains more nutrients but lower relative content and is released slowly, while chemical fertilizer has higher nutrient content and fewer components and release quickly. The organic acids produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and fertilizer. Organic fertilizer and chemical fertilizer promote each other, which is beneficial to crop absorption and improves the utilization rate of fertilizer.
Organic fertilizer is a plant, animal, they pass a period of time, after rotting decomposed into the fertilizer. Some people call it green manure, more widely. Inorganic fertilizers refer to fertilizers produced by chemical synthesis methods, including nitrogen, phosphorus, potassium, and compound fertilizers.
After the use of inorganic fertilizer, the effect is quick, easy to be absorbed by plants, but the fertility is not lasting; After the organic fertilizer fertilization, the effect is relatively slow, but the time is more lasting.
The use of inorganic fertilizer is too much, the soil surface becomes dry and stiff, and then easy to cause soil erosion, mineral loss, very large environmental damage. The soil becomes more barren and lacks many nutrients. The nutrient elements contained in organic fertilizer are mostly in the organic state, and it is difficult for crops to use them directly. Through the action of microorganisms, a variety of nutrient elements are released slowly, and nutrients are supplied to crops continuously. Applying organic fertilizer can improve soil structure, effectively coordinate water, fertilizer, air, and heat in the soil, and improve soil fertility and land productivity.
