The way of scientific fertilization
May 08,2024
In modern agriculture, fertilization is an important means to maintain soil fertility and improve crop yields. However, unreasonable fertilization can lead to soil pollution, waste of resources and even crop lodging. Therefore, scientific fertilization has become an urgent need for agricultural production.
Principles of scientific fertilization
1. Adapt measures to local conditions: Different soil types and crop types have different requirements for fertilizers. Fertilizer types and fertilization amounts should be selected according to actual conditions.
2. Reasonable collocation: fertilizer should be nitrogen, phosphorus, potassium and other elements reasonable collocation to meet the needs of crop growth.
3. Appropriate fertilization: According to the crop growth stage and weather conditions, choose the appropriate fertilization period.
Environmental protection priority: In the process of fertilization, environmental protection should be fully considered to avoid pollution of soil and water sources.
scientific fertilization method
1. Soil testing and formula fertilization: through the analysis of soil, understand the status of soil nutrients, formulate formulas according to crop needs, and achieve accurate fertilization.
2. Balanced fertilization: According to crop growth needs and soil fertilizer supply capacity, balanced application of base fertilizer and top dressing to ensure nutrient supply during crop growth.
3. deep fertilization: the fertilizer is applied into the deep soil to reduce nutrient loss and improve fertilizer utilization.
4. Irrigation and fertilization: combined with irrigation for fertilization, improve fertilizer absorption rate, reduce waste.
Matters needing attention in scientific fertilization
1. Avoid excessive fertilization: excessive fertilization can lead to crop lodging, reduced disease resistance, and even soil and water pollution.
Choose high-quality fertilizers: Buy high-quality fertilizers from regular channels and avoid using fake and inferior products.
3. Follow the fertilization safety interval: avoid excessive fertilization during the critical period of crop growth to avoid pesticide damage.
4. Combined with agricultural measures: scientific fertilization should be combined with farming, irrigation, pest control and other agricultural measures to comprehensively improve crop yield and quality.
