Dynamics of Diffuse pollution from us southern watersheds

摘要

to understand the effects of diffuse pollution information on the source of pollutants, quantities in transport, mode of transport, transient nature of the pollution event, and most importantly, a consideration of remediation efforts need to be known. For example, water quality resear4ch in the Yazoo Basin uplands in Mississippi has shown sediment loads from a conventional-till upland soybean watershed To be about 19,000 kg/ha/yr, and responsible for 77-96/100 of P and N in transport.
