Rotation and soil testing, formula fertilization, soil degradation

When the same crop is planted multiple times on the same land, the nutrient structure of the soil is destroyed and the soil is degraded. The performance is that the soil is not soft, easy to form a hard block, and the crop grows slowly and is prone to disease. This is very harmful to the soil. In order to avoid this situation, the rotation system and the soil testing formula fertilization technology should be adopted.

Rotation is to change the type of crops in turn, such as planting sweet corn, changing vegetables or rice, and then planting sweet corn in the second year. Different crops do not absorb fertilizers differently, and rotation can prevent the soil nutrient structure from being destroyed. Soil testing and formula fertilization is more elaborate. It selects soil samples, analyzes soil quality through instruments, and then rationally matches fertilizer varieties and dosages according to the characteristics of soil and crops.

This will prevent the waste of fertilizer and avoid damage to the soil and excessive fertilizer. At present, the rotation system and the soil testing formula fertilization technology have been promoted in many villages, and have achieved good results.
