Soil testing formula fertilization benefits

1. Increasing the yield of crops The test demonstration shows that since the implementation of soil testing and formula fertilization, adjusting the proportion of nitrogen, phosphorus and potassium in chemical fertilizers without increasing the investment in chemical fertilizers can play a role in increasing production and income.

2. Improve the utilization rate of fertilizers The soil testing and formula fertilization technology can optimize the application structure of fertilizers, increase the application of organic fertilizers, reduce the use of unreasonable fertilizers, and increase the fertilizer utilization rate by 5%.

3, change the traditional concept of fertilization The development of soil testing and formula fertilization can change the traditional fertilization concept of the peasants in the past, "the fat and water, no need to ask." In the fertilization method, it is changed from the application of the application, the application of the table to the deep application, and the direction of fertilization due to soil and crops, reducing the blindness of fertilization and improving scientificity.

4. Improve the quality of cultivated land. Soil testing and formula fertilization are carried out on the basis of rational application of farmyard manure. In the work of soil testing, the agricultural departments at all levels actively guided farmers to accumulate farmyard manure, implemented techniques such as returning straw to the field, improved the utilization level of organic fertilizer, improved soil nutrient structure, and improved the quality of cultivated land.

5, improve the level of scientific fertilization soil testing formula fertilization to take "measuring soil to the field, formula to long, fertilizer to point, guide to the household", to provide farmers with one-stop service, effectively meet the scientific fertilization of different places, different planting scales Claim.

6 Improve product quality Implement soil testing and formula fertilization, can coordinate the balance of crop reproductive growth and vegetative growth, promote the formation of nutritional quality of agricultural products, enhance disease resistance, stress resistance, reduce crop diseases, reduce the role of pesticides, and thus improve and improve The quality of agricultural products.

7. Reducing production costs The development of soil testing and formula fertilization has significantly improved the utilization rate of fertilizers and increased production. The average cost per acre is about 25 yuan.
