Abstract

Interflow is an important way and carrier of soil nutrient loss under rainfall erosion. At present, there are many domestic and foreign research results on the influence of surface runoff on soil nutrient loss, but the research on the effect of interflow on soil nutrient loss is still in the exploratory stage. This paper reviews the research work in the field of nutrient loss at home and abroad, focusing on the progress made in interflow on the loss of soluble organic carbon, nitrogen and phosphorus, and analyzing the existing problems and shortcomings. It is suggested that the study on the impact of soil flow on soil nutrient migration should be strengthened in the future, so as to provide basic data for ecological construction of soil and water conservation and prevention and control of agricultural non-point source pollution.
