Some Measures of Scientific Fertilization and Soil Improvement

To improve soil nutrients is not only to increase crop yields, but also to protect our country's soil environment and ecological balance. The use of soil testing and fertilizer applicators has linked scientific fertilization with soil improvement. Today we talk about scientific fertilization and soil improvement. Several measures.

1. Scientific fertilization and promotion of soil testing and formula fertilization

Using the soil nutrient fastness tester to carry out data and results of soil nutrient differentiation tests, according to the laws of fertilizer requirements of different crops, soil nutrient supply characteristics and fertilizer utilization effects, a fertilization recommendation card was developed. Farmers applied fertilization according to the recommendation card to apply fertilization by side effects.

2. Strengthen docking of agricultural enterprises and strengthen formula fertilizer promotion

According to the requirements of the relevant documents, the agricultural technology department, fertilizer production and sales companies, and farmers should carry out joint and close cooperation with each other and bear their respective responsibilities. The agricultural technology department provides formulas according to different types of areas and different crops, the fertilizer production enterprises guarantee quality and quantity production, and the fertilizer distribution companies provide farmers with reasonable distribution points in time, and the farmers apply fertilizer according to the technical guidelines. To realize the use of formula fertilizer in the whole county as a whole township, to give full play to the role of formula fertilization, to achieve scientific fertilization, and to promote the continuous and stable improvement of soil fertility.

3. Do a good job of soil fertility monitoring and establish a dynamic indicator system for fertilization

According to different soil types and different planting habits, 2 or 3 long-term monitoring points for soil fertility were established in each county to form a complete county soil fertility monitoring system, and dynamic indicators for fertilization of main crops such as wheat, rice, maize, and vegetables were established. system.

4, actively cultivate farmers scientific fertilization habits

Based on the techniques of soil testing and formula fertilization, the focus is to increase the use of commodity organic fertilizer, carry out straw comminution and field return, grow green manure to increase soil organic matter content, cultivate fertility, change farmers' heavy base fertilizer to lightly apply fertilizer, diazo light potassium, and weigh heavy elements. The fertilization habit of the trace elements in the promotion of potassium and nitrogen reduction, targeted trace elements in the supplement, reduce the amount of base fertilizer, increase the proportion of top dressing.
