Methods of fertilization What are the methods of fertilization?

1, fertilization is a reasonable way to put the nutrients needed by crops into the soil. Fertilization should not only meet the requirements of crops for nutrients, but also continuously improve soil fertility through fertilization. To achieve rational fertilization, we must follow the principles of "fertilization due to weather", "fertilization due to soil", "fertilization due to crops", "fertilization due to fertilizer" and "fertilization due to economic benefits".

2. Common fertilization methods are: base fertilizer. Fertilizer applied in combination with tillage before sowing. Supply the nutrients needed for the whole growth period of crops. Organic fertilizer with large dosage and slow fertilizer efficiency can be applied in several ways, such as spreading, strip application, layered application, ring application and radial application. Grow fertilizer. Fertilizer used for sowing or planting. On the one hand, it provides nutrients, on the other hand, it improves the physical properties of seedbed. Seed fertilizer generally uses high-decomposed organic fertilizer, quick-acting fertilizer and bacterial fertilizer. When applying seed fertilizer, it is necessary to guard against the possible corrosion and poison caused by the contact between fertilizer and seeds. Seed fertilizer can be applied by seed dressing, root soaking, seed soaking, strip application, hole application and seed covering according to different crops and fertilizer types. Topdressing The fertilizer applied during the growth and development of crops is a supplement to the fertilizer needed during the growth and development of crops, which generally requires the application of quick-acting fertilizers. There are several application methods, such as spreading, belt application, hole application, irrigation with water and root application.
