In agricultural planting activities, soil fertilization has the disadvantages of large application rates and environmental pollution. The soil test formula fertilization strongly advocated by the country can realize weight loss and reduce costs, and effectively ensure the fertilization effect. In view of this new fertilization technology, through the scientific application of the soil test formula fertilizer , the soil test formula fertilization can be made more scientific. Reasonable, the implementation is more in place.

The core of soil testing formula fertilization technology is to adjust and resolve the contradiction between crop fertilizer requirements and soil fertilizer supply. At the same time, targeted nutritional supplements are required for crops. What elements are missing from the crops are supplemented with as many elements as needed. Balanced supply of various nutrients can be achieved to meet the needs of the crops. To improve the utilization of fertilizers and reduce the amount of use, improve crops. Yields, improve the quality of agricultural products, save labor, save costs and increase income.

The scientific connotation of soil testing and formula fertilization can be divided into three stages: soil testing, formula, and fertilization. The first two are prerequisites, and the latter is the implementation process. Therefore, for different land fertilization, the formula is definitely different, so it can be said that It is unscientific to test soil and formula fertilize without neglecting the soil environment. Soil testing is actually very important. The soil test formula fertilizer can provide professional soil nutrient detection technology, help technicians quickly obtain soil nutrient data, and directly obtain scientific fertilizer formulas based on the test results, which strongly supports the current soil test formula fertilization work in various places.

The practical application shows that the soil testing formula fertilizer has a good soil nutrient detection effect, and the effect is obvious after the formula fertilization is implemented, and it has been well received by farmers. The popularization and application of the instrument will help materialize the soil testing formula fertilization technology into products, break the "hard ice" of the "last mile" of technology promotion, effectively improve the precision fertilization level in various places, and promote the efficient and ecological development of modern agriculture.
