Phosphorus is considered to be major limiting factor to freshwater eutrophication. Dissolved phosphorus within soil is the most active component for crop and animal production. Average annual soil loss was 2280 t km^-2 by ¹³⁷Cs technique. A single extraction coefficient was widely used to simulate desorption of phosphorus from soil to runoff. The relation between runoff dissolved phosphorus (y) and soil water-extractable phosphorus (x) is j=0.281x-0.179 (R=0.943). Soil water-extractable phosphorus lost at the rate of 0.371 kg km^-2 year^-1 during the soil erosion process. Phosphorus loss from soil to runoff was 0.090 kg km^-2 year^-1. Soil water-extractable phosphorus test is effective for evaluating the potential for soil to release dissolved phosphorus to runoff as the environmentally oriented soil phosphorus test.
