Quantifying the impact of no‐till on sediment yield in southern Brazil at the hillslope and catchment scales

No-till (NT) is a soil management system designed to protect resources from water erosion and provide numerous benefits compared conventional tillage through the increase of organic matter inputs into soil. However, NT in isolation not sufficient control processes caused by an excessive production surface runoff. This study evaluated losses on agricultural hillslopes under no-till characterized contrasted water, soil, crop conditions. To this end, were monitored between 2014 2018 at two scales, including four macroplots (0.6 ha; 27 events) paired zero-order catchments (2.4 63 events). The resulting dataset covered wide range rainfall conditions that occurred crop, runoff Hyetographs, hydrographs, sedigraphs constructed, these data used evaluate impact sediment yields, terraces, scarification, phytomass yield. installation terraces reduced yield 58.7%, mainly control. Crop increased input efficiently controlled (63%), although it did reduce volume peak flow. In contrast, scarification had no losses. current research demonstrated need combine leaving high amount therefore reinforces relevance monitoring strategy conducted scale methods select most effective conservation agriculture practices.
