Research on estimating the nitrogen pollutant load of agricultural drainage water in the Ningxia irrigation area based on the improved ECM model

Agricultural drainage water pollution in Ningxia irrigation areas is a significant factor affecting water quality in the Yellow River Basin. Based on the principle of total nitrogen (TN) input–output conservation, and incorporating irrigation and precipitation correction factors, an improved Export...
