An Effective Way to Improve Soil Organic Matter

(a) increase organic fertilizer. Organic manure is a good soil conditioner. It not only ripens the soil, maintains the good structure of the soil, but also enhances the soil's ability to retain fertilizers, fertilizers, and buffers. It constantly supplies the nutrients needed for crop growth and creates good soil for crop growth. condition.

(b) Straw returned to the field. Promote the use of wheat, corn, rice, etc., to return cropland to the field and spray the humectant technology, which can not only effectively use organic fertilizer resources, but also improve the soil structure, enhance soil fertility and fertilizer supply, save fertilizer input, and reduce production costs. Increase farmers' income.

(c) Intercropping crops. The implementation of crop rotation, intercropping system, and adjustment of planting structure to achieve a combination of land use and land conservation can not only maintain and increase soil organic matter content, but also improve the quality of agricultural products, and is of great significance in promoting the sustainable development of agriculture.

(D) planting green manure. The cultivation of green manure can provide rich organic matter and nitrogen for the soil, improve the agricultural ecological environment and physical and chemical properties of the soil, promote the combination of land use and land management, reduce the number of continuous cropping obstacles, reduce the use of chemical fertilizers, and increase soil organic matter content.

(v) Soil testing and formula fertilization. On the basis of soil nutrient testing and field trials of fertilizers, based on the laws of crop manure requirements, soil nutrient properties and fertilizer effects, based on the rational use of organic fertilizers, the use of nitrogen, phosphorus, potassium and the use of trace elements and fertilization were proposed. Period and fertilization methods to achieve organic balance with inorganic nutrients, reduce nutrient loss and environmental pollution, significantly increase crop content.
