摘要

Abstract Losses of soil‐derived P in overland flow induced by artificial rainfall were measured from six pastoral soils under a range of soil Olsen P concentrations. These soils were selected as being typical of the major soil groups that cover much of lowland Southland. Our objectives were to establish the magnitude and patterns of soil P release to overland flow under a wide range of soil Olsen P concentrations, established by amendment with either P fertiliser or dairy manure. The incorporation of superphosphate or manure into soils increased the soil Olsen P concentration as well as the concentration of P fractions in overland flow. There appeared to be no difference in the trend of P loss relative to Olsen P regardless of the form of P amendment. The magnitude of P loss appeared to be influenced by soil pedological origin, with lower dissolved reactive P (DRP) concentrations measured in overland flow from the Brown soils, compared to the less weathered Recent and Pallic soils. Regression analyses ind...
