Conselho Nacional de Desenvolvimento Científico e TecnológicoPhosphorus (P) plays an important role in eutrophication of aquatic systems and the streams and pond bed sediments are an important environmental compartment in this process. The bed sediment can act as a sink or source of P to the overlying water depending on their physicochemical and biological characteristics. The objective of the present study was to evaluate the P dynamics in bottom sediment of ponds and streams and to determine their potential to adsorb or release P due to human activities in two agricultural watersheds. The watersheds, with an area of 1,426 km2 (PBH140) and 0.783 km2 (PBH80), are located in a landscape in the city of Júlio de Castilhos, State of Rio Grande ...
