Background
In the agricultural production process, due to excessive input of chemical fertilizers, the fertilizer utilization rate is low, the nitrogen and phosphorus nutrient residues in the soil are high, and under the influence of rainfall and irrigation, the nitrogen and phosphorus nutrient downwards migrates in the soil through leaching, finally enters underground water, and causes groundwater pollution, so that the nitrogen and phosphorus nutrient downwards migrates into the soil to become a main source of agricultural non-point source pollution. Leaching refers to a process in which soluble or suspended compounds in soil materials migrate from the top to the bottom of the soil under the influence of water leakage, or laterally. The non-point source pollution condition of nitrogen and phosphorus in the farmland can be judged through detection and analysis of underground leaching water in the farmland, so that management strategies such as farmland fertilization and irrigation can be adjusted in a targeted manner.
