Organic fertilizers contain a wide variety of nutrients, which is an advantage over single-nutrient fertilizers. When applying organic fertilizer, fertilizer should be applied according to the nutrient requirements of the crop. Even in fields where organic fertilizer equipment  produces green food, mineral fertilizers should be applied in appropriate amounts, and various foliar fertilizers should be applied in the process of crop growth.

Although organic fertilizers contain a variety of nutrients, their nutrient content is low and they decompose slowly in the soil. When the amount of organic fertilizer is not very large, it is difficult to meet the needs of crops for nutrient elements. The fertilizer has high nutrient content and fast fertilizer effect, which can be supplemented according to the needs of crops, but the fertilizer effect period is short. In order to obtain high yield, organic fertilizers and fertilizers should be applied together, draw on each other's strengths, give full play to their respective advantages, and meet the needs of crops for various nutrients in quantity and time. Fully decomposed organic fertilizer should not be mixed with alkaline fertilizer, so as not to cause ammonia volatilization and reduce the nutrient content of organic fertilizer.

Organic fertilizer contains more kinds of nutrients, and has advantages compared with single-nutrient fertilizer, but the nutrients it contains are not balanced, and can not meet the needs of high yield and quality of crops. When applying organic fertilizer, fertilizer should be applied according to the nutrient requirements of the crop. Even in fields that produce green food, mineral fertilizers should be applied in appropriate amounts, and various foliar fertilizers should be applied during the growth of crops. In order to obtain high yield, organic fertilizer production lines should be used to produce organic fertilizer, draw on each other's strengths, give full play to their respective advantages, and meet the needs of crops for various nutrients in quantity and time.
