The results of the national soil survey show that the organic matter content of farmland soil in many areas of China is already below the warning line, serious consolidation of large areas of the land, soil fertility has been red light, etc., through the analysis we can know, resulting in reduced soil quality of cultivated land The main reason is that due to long-term unreasonable increase in the use of inorganic fertilizers, with or without the application of organic fertilizers, etc., so in order to improve the soil properties, modern agriculture pays more attention to the rationality of fertilization, and the application of the instrument can help The agricultural workers scientifically applied chemical fertilizers, guided the application of organic fertilizers, and comprehensively improved soil fertility so as to achieve the purpose of effectively improving soil production and environmental conditions.
The soil tester is also called soil fertilizer meter, soil nutrient speed meter, etc. It is a special soil testing instrument for rapidly testing and measuring soil nutrients. To carry out soil testing, formula fertilization, scientific fertilization, and to understand the nutrient status of the soil are the most basic and necessary. Therefore, in the modern agricultural development, the application of the soil tester is very important. In general, the application process of the soil tester is mainly divided into the following steps.
First, the soil tester is applied to soil testing, so the first step is to determine the scope of soil testing, select the most representative land for soil testing, the first step is how to scientifically select soil, and then take soil, Take these soils as a sample.
Second, after the completion of soil sample selection, it is the formal soil testing process. The soil tester can quickly determine the nutrient content of the soil and obtain the required soil test results in a short period of time.
Thirdly, soil fertility test report is given based on the results of the soil tester to provide basis for soil testing and formula fertilization.
Fourth, according to the specific soil fertility test report, combined with the planted crops, provide targeted fertilizer recommendations for each plot.
The fifth and final step is to conduct scientific fertilization and scientific planting based on these fertilization proposals, and to scientifically fertilize and manage the crops, thereby gaining a large harvest of agriculture.
The above is a description of the application process of the soil tester. Currently, soil testing and formula fertilization has become an important technology for optimizing the agricultural environment, increasing the level of fertilization, reducing resource waste, and increasing agricultural output and quality, which is of great significance for leading farmers to increase production and income. Therefore, in order to ensure the advancement of soil testing and formula fertilization techniques, the soil testing instrument should be vigorously promoted at the grassroots level to increase the scope of application of the soil testing instrument.
