Soil compaction refers to the lack of organic matter and poor structure in the surface layer of the soil. Under the effects of irrigation or rainfall, the structure of the soil is destroyed and soil material is dispersed. After drying, the soil is hardened by the cohesive force. The hazards of soil compaction include: 1. The ability of the root system to decline. Soil compaction, lack of oxygen leads to decreased root activity, can not be normal development, plant roots, cell respiration is weakened, the absorption of nutrients in the consumption of metabolic energy generated by cell metabolism, affect the absorption of nutrients. 2, leading to the occurrence of a deficiency of the disease. The deficiency of the disease is not necessarily the lack of such elements in soil, but because of a series of problems such as soil compaction, inappropriate PH value, or unbalanced supply of soil moisture. Soil compaction remedies: 1, increase the application of organic fertilizer. Apply high-quality organic fertilizer, it is best to use high levels of microbial agents. 2. Raise farmers' awareness of the effects of various fertilizers and reduce the amount of fertilizer applied. Through the promotion of soil testing and formula fertilization, the amount of blindly applied chemical fertilizers is controlled, unreasonable investment is reduced, and economic benefits are increased. 3, promote dry farming, implement sprinkler irrigation; use more summer storage of rainwater, make full use of the ground water. 4. Break the old farming methods and further promote straw returning. No-tillage coverage should minimize soil loss to ensure that the soil structure is not damaged.
