What is the use of applying organic fertilizer? Please explain
Organic fertilizer refers to any substance that contains organic matter and can provide a variety of nutrients for crop growth and development. Organic fertilizer has many advantages, such as building soil fertility, improving plant nutrition, and releasing nutrients over a long period, and is an important source of fertilizer in agricultural production.
Because organic fertilizer has advantages that chemical fertilizers cannot replace, people have always paid great attention to the production and use of organic fertilizer in agricultural production. But some people believe that the more organic fertilizer applied, the better, and this view is not correct. Because organic fertilizer, like chemical fertilizer, also involves the issue of measured application in agricultural production. If too much organic fertilizer is used, it is not only a waste, but can also cause soil problems and affect crop growth. For example, in protected vegetable production, if organic fertilizer is applied in large amounts over a long period, it can also lead to excess soil nitrogen, which in turn causes nitrate levels in vegetable products to exceed the standard and affects human health. Therefore, the amount of organic fertilizer applied in production should be used rationally according to the consumption of various nutrients and organic matter in the soil, and formula fertilization should be carried out.
