Agricultural runoff can be a source of P, a limiting factor for freshwater eutrophication. To develop a simple method to estimate P export from the cropland, we studied 1.2-μm filtered dissolved phosphorus (DP) output from four tiles draining areas ranging from 8 to 25 ha, and from a river draining a 48173 ha watershed in east-central Illinois during 1993 to 1996. The land was under maize (Zea mays L.)-soybean (Glycine max L.) rotation. The tiles were estimated to contribute more than 86% of… Expand
