Managing runoff in rainfed agriculture under no-till system: potential for improving crop production

First Evidence of Widespread, Severe Soil Erosion Underneath Centre-Pivot Irrigation Systems

“…To address management challenges associated with centre-pivot irrigation, such as high water-application rates and the potential for wheel-track compaction, soil conservation practices that promote soil cover and soil water infiltration and prevent harmful runoff concentration during both irrigation and the summer-concentrated rainfall are required. These include zero tillage, reservoir tillage, broad-based terracing, retention basins, and grassed waterways (Fiener and Auerswald, 2003;Hörbe et al, 2021;Silva, 2017). Although zero-tillage is widely employed in the Brazilian Cerrado, this technique alone is not always sufficient to prevent soil erosion and combining it with other soil conservation practices, such as broad-based terracing, has been shown to be more effective (e.g., Didoné et al, 2017;.…”

Surface runoff and soil erosion from Nitisols and Ferralsols as influenced by different soil organic carbon levels under simulated rainfall conditions

“…Therefore, soil erosion by runoff remains a major concern especially in the developing countries where it seriously threatens agricultural productivity and food security [ 15 ]. This can significantly reduce the production capacity of agricultural lands [ 16 ]. For instance, the annual crop yield loss in Africa is estimated to be 280 million tons due to erosion [ 17 ].…”
