Organic fertilizers include all substances that can be used as fertilizers, except for chemical fertilizers, usually including human and animal manure, crop straw, and green manure. Organic fertilizers have comprehensive nutrients and long-lasting and balanced fertilizer effects. They can improve soil structure, improve soil fertility, promote the release of soil nutrients, and supply crop nutrients, which is of great significance for the development of organic agriculture, green agriculture, and pollution-free agriculture. But there are many types of organic fertilizers with different functions, so the application should be scientific and avoid blind application.

Advantages and disadvantages of organic fertilizers compared to other fertilizers

Organic fertilizer nutrient imbalance

Organic fertilizer contains a variety of nutrients, which is an advantage compared to single nutrient fertilizers. However, its nutrient content is not balanced and cannot meet the needs of high yield and high quality crops. When applying organic fertilizers, chemical fertilizers should be applied according to the nutrient requirements of crops. Even in farmland producing green food, appropriate amounts of mineral fertilizers should be applied, and various foliar fertilizers should be applied during crop growth.

Advantages and disadvantages of organic fertilizers compared to other fertilizers

Low nutrient content in organic fertilizers

Although organic fertilizer contains a variety of nutrients, its content is relatively low and it decomposes slowly in the soil. When the amount of organic fertilizer applied is not very large, it is difficult to meet the nutritional needs of crops. However, chemical fertilizers have high nutrient content and rapid fertilizer efficiency, and can be supplemented in a targeted manner according to the amount needed by crops, but the fertilizer efficiency period is short.

In order to achieve high yields, organic fertilizers and chemical fertilizers should be applied in combination, complementing each other strengths and weaknesses, and leveraging their respective advantages to meet the crop needs for various nutrients in terms of quantity and time.
