ABSTRACT Water erosion is one of the main environmental impacts of land use. When soil and water losses occur, nutrients essential for the growth and maintenance of plants are removed, with harmful outcomes on the sustainability of agriculture and the environment. In addition, they lead to other deleterious effects, such as sedimentation and eutrophication of water bodies. Estimation of soil losses due to water erosion in sub-basins is essential for prediction of soil degradation, especially in areas of semi-intensive cultivation, […]

ABSTRACT Water erosion degrades the soil and contaminates the environment, and one influential factor on erosion is slope length. The aim of this study was to quantify losses of soil (SL) and water (WL) in a Humic Cambisol in a field experiment under natural rainfall conditions from July 4, 2014 to June 18, 2015 in individual events of 41 erosive rains in the Southern Plateau of Santa Catarina and to estimate soil losses through the USLE and RUSLE models. The […]

Tillage is one of the most important components of soil management in the process of crop production, normally used to create a favorable environment for sowing, seed germination and plant development. In addition, it is mainly determinant for the or surface soil physical conditions that will ultimately determine the erosion and the effectiveness of runoff reduction of the various soil management systems used to establish a given crop, in a given place. Considering these aspects, a field study under natural […]
