Soil compaction Soil compaction refers to the phenomenon that the soil surface layer is tightly packed due to the lack of organic matter and water, and it is difficult for air and water to penetrate. This phenomenon can seriously affect the growth of crops and reduce the yield and quality of crops. Therefore, it is an important task in agricultural production to solve the problem of soil compaction and improve soil fertility. In this paper, we will introduce several effective soil compaction treatment methods.
2. Causes of soil compaction.
The main causes of soil compaction are as follows:
1.Long-term over-tillage destroys the soil structure, reduces the number of organic matter and microorganisms in the soil, and leads to soil compaction.
2.Irrational irrigation methods, such as flood irrigation, can cause too much moisture in the soil, leading to soil compaction.
3.Excessive use of chemical fertilizers, especially nitrogen fertilizers, can lead to soil acidification, damage to soil structure, and trigger soil compaction.
3. Treatment method of soil compaction.
1.Subsoiling operation: Subsoiling operation is one of the effective methods to improve soil compaction. Through subsoiling operation, the tight structure of the soil surface can be broken, and the aeration and permeability of the soil can be increased, which is conducive to the growth and development of crop roots.
2.Application of organic fertilizer: Organic fertilizer is rich in organic matter and microorganisms, which can improve soil structure and increase soil fertility. At the same time, organic fertilizer can also regulate the pH of the soil and prevent soil acidification.
3.Reasonable irrigation: Reasonable irrigation methods can reduce excessive moisture in the soil and prevent soil compaction. For example, water-saving irrigation methods such as drip irrigation and infiltration irrigation can be used.
4.Planting green manure: Green manure is a plant that both improves the soil and provides fertilizer for crops. Planting green manure can increase organic matter and microorganisms in the soil, improve soil structure and prevent soil compaction.
5.Proper fertilization: Excessive use of chemical fertilizers can lead to soil acidification, damage to soil structure, and trigger soil compaction. Therefore, fertilization should be done reasonably, both to ensure the nutrient needs of crops and to avoid over-fertilization.
IV. Conclusions. Soil compaction is an important factor affecting agricultural production, which requires effective methods to be managed. Through subsoiling operations, application of organic fertilizer, reasonable irrigation, planting of green manure and reasonable fertilization, soil compaction can be effectively improved, soil fertility can be improved, and the growth and development of crops can be promoted.
