There are two main application methods of organic fertilizer and inorganic fertilizer:
One is to use organic fertilizer as the base fertilizer, and the chemical fertilizer is the top dressing or seed fertilizer; the second is to directly apply organic fertilizer and chemical fertilizer; Mixing to improve fertilizer efficiency, some to reduce fertilizer efficiency, such as nitrate nitrogen fertilizer and unfertilized organic fertilizer mixed together, under anaerobic conditions, due to denitrification, it is easy to cause nitrate nitrogen loss and nutrient loss. Reasonable fertilization and giving full play to the effect of increasing fertilizer production are important measures to achieve high yield, stable production and low cost.Reasonable cooperation, organic fertilizer and chemical fertilizer, nitrogen, phosphorus mutually promote, is an important principle of rational fertilization.
Organic fertilizer is rich in nutrients, fertilizer efficiency is low, fertilizer concentration is high, and the effect is fast. In particular, organic fertilizer contains a lot of organic matter, which forms humus through the action of microorganisms, which can improve the soil structure, make it loose and soft, and have good ventilation. It is not only conducive to the growth and development of crop roots, but also conducive to improving the soil's water retention performance and protection performance. Fertility. Fertilizers can provide available nutrients needed for microbial activities, accelerate microbial reproduction and activities, promote the decomposition of organic fertilizers, release large amounts of carbon dioxide and organic acids, and help dissolve poorly soluble nutrients in the soil. Therefore, organic fertilizers and chemical fertilizers are used in combination to complement each other and make full use of these two fertilizers.
