Do Randomly Placed Riparian Conservation Land-Uses Improve Stream Water Quality in Iowa, USA?Polish Journal of Environmental Studies
Publication VersionPublished Version
AbstractTo improve stream water quality in the United States, government programs subsidize farmers to establish riparian conservation land-uses in agricultural landscapes. This study compared sediment and phosphorus water concentrations from stream reaches adjacent to riparian forest buffers, grass filters, row-cropped fields, pastures with cattle fenced out of the stream, and continuous, rotational and intensive rotational pastures in Iowa. In some cases agricultural land-uses had significantly higher sediment and phosphorus concentrations, while in others the conservation land-uses were higher. The few significant differences between conservation and agricultural land-uses suggest that the random placement of conservation land-uses is an inefficient way to improve water quality.
