Price of soil testing equipmentThe testing of soil detection is a whole process, including sampling, testing, and judgment of results. The tested items include available nitrogen, phosphorus, potassium, soil pH value, etc., which can comprehensively understand the current condition of the soil and strengthen soil pollution prevention and control. The use of soil detection instruments for soil detection is an important foundation for understanding soil.

To ensure that our soil testing results are more accurate, we must pay attention to soil sampling and processing. When collecting samples, we cannot repeat sampling in one place. We should adopt a random sampling method and try to let the samples touch the entire plot as much as possible, so as to better reflect the actual situation. In addition, impurities in the samples should also be cleaned up to avoid affecting the soil testing itself.
