Agricultural land use on slope areas is susceptible to nutrition loss via surface runoff, which would result in negative impacts on downstream waters. However, the linkage between nutrition loss and off-site crop production has been rarely reported. A study was conducted in a small independent agroforestry watershed in subtropical hilly terrain of China. Nutrition loss via surface runoff was measured from cropland, tea garden, citrus orchard, and natural woodland on a slope area. Grain production of rain-fed uplands and irrigated rice paddies w...
