Effects of Agricultural Practices and Land Disposal of Solid Waste on Quality of Water from Small Watersheds.

摘要

Samples of runoff water were collected from each of four watersheds as it was subjected to a specific cropping,tillage,fertilization,or waste disposal treatment. Runoff water quality constituents examined include:nitrates,phosphates,chlorides,dissolved solids,sediment,turbidity,suspended matter,BOD,DO,fecal coliform,and 13selected metals. The data were analyzed by seasons in order to best relate constituent concentrations to watershed and rainfall-runoff conditions.
