The soil testing and formula fertilizing instrument can effectively solve the contradiction between crop fertilization, soil fertilization, and crop fertility requirements, and can supplement the shortage of nutrients needed for crops in a targeted way, so that scientific and rational use of fertilizer can be achieved, and what elements are lacking in soil can be supplemented. What elements, what elements need to be supplemented by crops, how much they need to be supplemented, and the balanced supply of nutrients to meet the needs of crops.

Farmers gradually established a concept of scientific fertilization based on the characteristics of soil fertility and crop manure requirements. The improper fertilization methods and phenomena such as “a pack of ammonium bicarbonate and a pack of phosphate fertilizers are used in the end”, single application, partial application, and indiscriminate application are gradually decreasing. The proportions of fertilizers and compound fertilizers are gradually increasing. Rational application of soil testing and fertilizer application instruments and some related advanced instruments have resulted in a reasonable structure of soil nutrients and more scientific and reasonable fertilization.

Compared with 2004, wheat varieties mainly consisted of Zhengmai 9023, rice was mainly composed of Liangyou, and pest control measures were almost the same each year. The difference was that soil fertility tests had been implemented since 2005. By measuring the effect and nutrient of the soil testing and formula applicator, it can be seen that the part of the increase in production in 2012 compared with that in 2004 was basically caused by soil testing and formula fertilization, and the contribution rate of fertilizer to the crop yield increase, Or that the contribution to agricultural science and technology is still the first.

Through extensive publicity, technical training, and demonstration demonstrations, the popularization and application of soil testing and fertilizer application technology will be greatly improved. The use of soil testing and formulating fertilizer applicators and the demonstration of the project technology to significantly increase the advantages and effects of production, has been fully affirmed and recognized by the majority of peasants, so that soil testing and fertilizer application technology has become a conscious behavior of farmers believe in science, master science, applied science.
