The first is to reduce energy consumption. Due to the unreasonable structure of fertilizer, only Henan Province lost 2.4 million tons of nitrogen fertilizer a year, which is equivalent to the output of 10 small and medium-sized nitrogen fertilizer plants.
The second is to increase production. Soil testing, formula fertilization has an average yield increase of more than 10% over traditional fertilization food crops, and cotton, oilseeds, vegetables and other economic crops have an average yield increase of more than 15%.
The third is cost increase. Excessive fertilization in some areas of China, the south part of the rice soil testing and formula fertilization can save 30 kilograms per mu, according to the current price, reduce the cost of 20 yuan per mu.
The fourth is to improve the environment. Soil testing and formula fertilization can increase fertilizer use efficiency by 5 percentage points, effectively reduce nutrient infiltration into the ground or inflowing rivers, reduce surface pollution of chemical fertilizers, and increase soil fertility.
The fifth is to reduce pests and diseases. Studies have shown that most crop diseases are caused by imbalances in nutrients, especially the lack of potassium and trace elements. After soil testing and formula fertilization, the occurrence of crop diseases can be greatly reduced.
Sixth, improve the quality of agricultural products. Soil testing and formula fertilization can change the habit of partial application of nitrogen fertilizer, reduce the nitrate content of vegetables, prevent fruit from becoming acid, and improve the thickness, lightness, and intrinsic quality structure.
