In agricultural production, the low utilization rate of chemical fertilizers has always been an important issue for farmers, especially in large-scale agricultural cultivation. The utilization rate of chemical fertilizers is not high, and it is difficult to promote high-quality and high-yield crops, but also increase planting costs. Soil quality, etc., so the scale of planting to lose weight and increase efficiency, the most effective way is scientific soil testing, precision fertilization. The use of a soil tester to do nutrient testing of the soil can provide important guidance for the scientific and rational application of chemical fertilizers and effectively increase the utilization rate of chemical fertilizers.
At present, with the adjustment of agricultural structure, soil testing also puts forward several requirements. The first is to be precise, only when the measurement is accurate, it can ensure the scientificity of formula fertilization and improve the effect of fertilization; the second is quick and fast soil. Detection can effectively save time, ensure the smooth implementation and development of soil testing and fertilizer application; the third is to adapt to a wide range of soil to meet the determination of different areas; the fourth is simple, easy to use. The soil tester combines the features of accuracy, rapidness, wide adaptability and simple operation, and is an ideal instrument for soil nutrient determination in the agricultural field.
In the field of agricultural production, fertilizers are not applied as much as possible, but should be appropriate and timely. The use of a soil tester to understand soil conditions can be based on a full understanding of soil nutrient abundance and soil nutrient performance, according to the crop's fertilizer requirements and characteristics to carry out scientific fertilization, and then to improve the efficiency of fertilizer use . Increasing the utilization of chemical fertilizers is actually equivalent to increasing the amount of chemical fertilizers used, reducing costs, and increasing the economic benefits of chemical fertilizers. Therefore, it can be said that the application of earth tester has played an important role in promoting the efficiency of modern agriculture, and brought real benefits to farmers.
