1. Increase the output of crops The demonstration experiment shows that since the implementation of soil testing and formula fertilization, without increasing the investment in chemical fertilizers, adjusting the ratio of fertilizer N, P, and K can play a role in increasing production and income.
2. Increase the utilization rate of fertilizer The soil testing and formula fertilization technology can optimize the application structure of fertilizers, increase organic fertilizers, reduce the use of unreasonable chemical fertilizers, and increase the fertilizer utilization rate by 5%.
3. Changing Traditional Fertilization Concepts The development of soil testing and formula fertilization can change the traditional fertilization concepts of farmers who used to be “hypertrophic and water-threatening, no need to askâ€. In the fertilization method, the direction of application of fertilization, application of surface fertilizers to deep application and soil, and crops need to be changed. This will reduce the blindness of fertilization and improve scientificity.
4. Improving the quality of cultivated land Soil testing and formulating fertilization is based on the rational application of farmyard manure. In carrying out the soil testing formulation work, agricultural departments at all levels actively guided farmers to accumulate farmyard fertilizers, implement techniques such as returning crop residues, and improve the use of organic fertilizers so that the soil nutrient structure was improved and the quality of cultivated land was significantly improved.
5, improve the level of scientific fertilization soil testing and formulating fertilization to "test soil to the field, formula to long, for the fertilizer to the point, guide the household" to provide farmers with one-stop service, effectively meet the different places, different planting scale scientific fertilization Claim.
6 Improve Product Quality The implementation of soil testing and formula fertilization can coordinate the balance of crop reproductive growth and vegetative growth, promote the formation of agricultural nutritional quality, enhance disease resistance, resilience, reduce crop disease, reduce the role of pesticides, and thus improve and improve Quality of agricultural products.
7. Reducing Production Costs The development of soil testing and formula fertilization has resulted in a significant increase in the utilization rate of fertilizers and an increase in production. The average cost per acre is about 25 yuan.
