Why should organic fertilizer be fermented completely? What should we pay attention to when using it
Date:2020/01/15
When using organic fertilizer machine to treat fermented feces, there are a lot of pathogenic microorganisms and parasitic Ascaris eggs in the immature feces.
After the application into the farmland, some of them attach to the crops and cause direct pollution, and some of them enter the soil and cause indirect pollution. In addition, the manure organic fertilizer without maturity can only be absorbed and selected by crops after being fermented. On the one hand, high temperature will cause seedling burning, on the other hand, ammonia will be released, which will cause poor plant growth. Therefore, the manure organic fertilizer must be fully decomposed when applied.
(1) The nutrients contained in organic fertilizer are not omnipotent. There are many kinds of nutrients in organic fertilizer, which is better than chemical fertilizer with single nutrient. However, the nutrients in organic fertilizer are not balanced and can not meet the needs of high yield and high quality of crops.
(2) The decomposition of organic fertilizer is slow and the fertilizer effect is late. Although the content of nutrients in organic fertilizer is all, but the content is low, and decomposition is slow in the soil, it is difficult to meet the needs of crops for nutrients when the amount of organic fertilizer is not large.
(3) Organic fertilizer needs to be fermented. Many organic fertilizers contain germs, insect eggs and weed seeds. Some organic compounds are harmful to the growth of crops. Therefore, they can only be used after composting, fermentation and processing, and the raw manure can not be put on the ground.
