Soil is the basis of plant growth, and the quality of its fertilizer supply directly affects the growth of plants. In order to maintain and improve the fertilization of the soil, we can adopt a series of methods to adjust.
1. Increase the application of organic fertilizer.
Organic fertilizer is a valuable asset for agricultural waste and biomass resources, such as crop straw, animal manure and oil crop scraps. They are rich in mineral elements and organic matter, which can not only improve the fertility of the soil, but also adjust the pH value of the soil and enhance its ability to retain fertilizer and water. Through direct accumulation, cake fertilizer making, pure natural mineral fertilizer and well-rotted pond mud, we can easily make efficient organic fertilizer. It is recommended that farmers use organic fertilizer every two years and alternate biological fertilizers to ensure the continued fertility of the soil.
2. Supplement compound microbial fertilizer.
Compound microbial fertilizer is rich in a variety of microbial flora, such as bacteria, fungi, etc. These microorganisms multiply actively in the soil, helping to release fixed nutrients in the soil, increasing nutrient content, and promoting nutrient cycling. This not only enhances the fertilization of the soil, but also improves the efficiency of nutrient uptake by plants.
3. Timely replenishment of minerals and trace elements.
Minerals and trace elements in the soil are essential nutrients for plant growth**. When the soil is deficient in these elements, the growth of plants will be restricted. At this time, we can add mineral fertilizers or foliar sprays to ensure the healthy growth of plants.
Fourth, reasonable crop rotation and planting leguminous forage.
A proper crop rotation system can help restore soil fertility and reduce pests and diseases in the soil. The planting of leguminous forage grasses, such as soybeans and alfalfa, can provide rich organic matter for the soil, increase the nitrogen content in the soil, and further improve the fertility of the soil.
5. Scientific irrigation and soil moisture management.
Proper irrigation ensures that the moisture content in the soil is moderate, neither too much nor too little. Too much water can lead to nutrient loss, while too little water can affect the uptake of nutrients by plants. Therefore, scientific irrigation and soil moisture management are essential to maintain and improve the fertility of soil.
In summary, regulating the fertilization of the soil is a key task in agricultural production. Through the comprehensive application of various measures such as increasing organic fertilizer, supplementing compound microbial fertilizer, timely supplementation of minerals and trace elements, reasonable crop rotation and planting of leguminous forage, scientific irrigation and soil moisture management, we can ensure that the soil maintains good fertility and suitable soil structure, so as to create the best conditions for plant growth.
