| Abstract: | Soil erosion and nutrient loss are not only problems of agriculture, but also problems of ecological environment. Nutrient loss directly leads to the rich topsoil erosion, land degradation and declines of productivity levels. Through the research review of runoff, sediment and nutrient loss characteristics in slope farmland and control technology, this paper aims to provide theoretical guidance for research of nutrient loss. |
