Precision fertilization is an important goal in modern agricultural production, and to achieve precise fertilization, three points are critical. The first is to know how much nutrients are needed for the crops grown; the second is to know exactly what nutrients are missing in the soil; the third is to rationally plan to use the corresponding fertilizers. To understand the lack of soil nutrients, we can use the soil testing formula fertiliser to detect. The soil testing formula fertilization instrument is one of the important soil instruments in the field of soil testing and formula fertilization technology. Its role is mainly to detect the nutrient content in the soil and provide a scientific basis for soil testing and formula fertilization. Soil testing and formula fertilization is mainly based on soil testing and testing, determining the appropriate amount and proportion of crop nitrogen, phosphorus, potassium and medium and micro fertilizers, and then guiding farmers to determine the practical techniques of fertilization period and fertilization methods. Therefore, the importance of soil testing is self-evident, and in order to improve the efficiency and accuracy of soil nutrient testing, the use of soil testing formula fertiliser is the most ideal way. This kind of quick-checking instrument with simple operation and fast measuring speed can provide good technical support for the promotion and application of formula fertilization technology, help the successful implementation of soil testing and formula fertilization operations, and give full play to the maximum yield increase of fertilizer. The quality of cultivated land is the basis for ensuring agricultural production and efficiency. Therefore, in recent years, thousands of acres of standard farmland quality improvement projects, "fertile soil engineering", farmland quality protection and upgrading actions have been carried out. Only by understanding the soil can we better protect the soil and develop and use the land, so soil testing is always the most important task. In the process of implementing fertilizer reduction in various places, the soil testing formula fertilization instrument was used to accurately understand the lack of soil nutrients, obtain soil nutrient data, and scientifically implement precise fertilization, and achieved good results. Through these effective measures, the environment has been protected, the quality of cultivated land has been improved, and the cost has been reduced, and weight loss and efficiency have been achieved. For modern agricultural production, this technology is a cost-effective technology that should be widely promoted and applied.
