Runoff and soil losses from agricultural fields are investigated as major nonpoint sources of phosphorus (P) entering lakes of Eastern China. There is relatively.little information on P transport from ricefield and cropland of Lake Taihu w.tershed in Eastern China. Soil and P in surface runoff from a series of plots in the w.tershed w.re evaluated under simulated rainfall conditions. The objectives of this study.w.re to evaluate the effects of crop cover, slope, and fertilizer application on P concentrations in surface runoff and eroded soil. Accumulated sediment y.elds varied from 7.1 to 300 g/m2 for croplands, depending on management practices. For all experiment plots, w.ighted average concentrations of total-P (TP), dissolved P (DP) and particulate P (PP) are much higher than 0.02 mg/L, the limiting concentration for lake w.ter. This result show.d the potential contamination of lake w.ter from agricultural surface runoff. Accumulated TP losses w.re 3.8 and 18.8 mg/m2 for ricefield and cropland, respectively. The estimated annual loss of TP w.s 0.74 kg/(hm2 · a) for cropland. Most of P loss is in the PP form, w.ich accounts for more than 90% of TP loss for cropland.
