Reclaimed water irrigation is one of the most important ways to solve the shortage of water for agriculture in China. Utilizing reclaimed water to replace conventional water resources is suitable for the rapid growth of China's water demand, and can reduce pollutants discharged from surface water and lower the cost of sewage treatment. Therefore, using reclaimed water for irrigation is an inevitable choice to achieve urban wastewater reuse and reduce clean water and pollutant emissions. Reclaimed water brings rich nitrogen, phosphorus, organic matter and other nutrients to soil and crops, improves soil physicochemical properties, and increases soil fertility. However, some studies have shown that too much organic matter in reclaimed water can lead to a reduction in soil porosity, which reduces soil water-holding capacity and hydraulic conductivity, leading to soil...
