TL;DR: In this article, the authors quantify the chemical changes in the soil caused by lime application with different Ca:Mg ratios 141 months after its application and show that the use of calcitic lime provided more significant alterations in the attributes related to soil acidity in the profile compared to the dolomite.

TL;DR: In this article, the authors investigated the sediment source contribution in two paired agricultural catchments with different proportions of riparian vegetation and wetlands, and similar proportion of crop fields, by using the fingerprinting approach.

TL;DR: In this paper, a bacias hidrografica localizada no municipio de Julio de Castilhos, Rio Grande do Sul, Brazil, was used to identify fontes of sedimentos.

TL;DR: Findings indicate that agricultural practices, sediment characteristics, and hydrological factors have a major impact on seasonal sediment P bioavailability and mobility and the urban untreated discharges may be a single major P source and, if it is not wisely managed, proves a major threat to water quality.

TL;DR: In this article, the concentration of nitrate and soluble phosphorus (P) in the stream water were assessed in a rural watershed under intensive agriculture and livestock production in southern Brazil, where water samples were collected at 11 points along the drainage system in three different periods.
