Water scarcity and water-related soil erosion are severely exacerbated by inappropriate human activities global climate change. Hence, to find a suitable technology mitigate drought erosion, three consecutive field experiments were conducted explore the impact of ridge-furrow cropping with biochar amendment on water storage, runoff, sediment yield, nutrient losses, alfalfa (Medicago sativa L) fodder crop productivity (WPc), economic benefit from 2019 2021. This experiment was in split-plot...

Abstract In dryland areas, integrating biochar soil amendment with in situ rainwater harvesting systems may decrease erosion, improve quality, and increase crop productivity yield. This study was conducted to investigate the effect of maize straw ridge‐furrow on run‐off, sediment yield physico‐chemical properties a Calcic Cambisol semiarid areas. The experiment alfalfa ( Medicago sativa ) production land at Anjiagou Catchment experimental station Gansu province, China. layout split‐plot...

Ridge-furrow rainwater harvesting (RFRH) is known to be effective in controlling water loss and soil erosion, increasing moisture crop yield semiarid regions. However, it can cause waterlogging, ridge overtopping, harvest failure if not properly designed. A four consecutive-year field trial was carried out assess the impacts of various slope gradients tillage practices on moisture, runoff, sediment yield, associated nutrient losses, fodder use efficiency (WUE) alfalfa Loess Plateau, China....

Loss of organic matter and mineral nutrients to soil erosion in rain-fed agriculture is a serious problem globally, especially China's Loess Plateau. As result, increasing rainwater usage efficiency by tied-ridge-furrow harvesting with biochar expected improve agricultural productivity. Nonetheless, limited knowledge on biochar, small-scale farmers face the challenge adoption, thus, rationale for this study.A field experiment was conducted determine influence open-ridging (OR) tied-ridging...

Ridge-furrow rainwater harvesting (RFRH) with mulch offers farmers means to address drought, water loss, and soil erosion in arid semiarid regions. Plastic film is widely used as a mulching material for RFRH; however, contamination of arable lands by its residual serious concern. We compared various mulches, including biodegradable RFRH planted sainfoin (Onobrychis viciifolia). A field study was conducted (1) estimate runoff efficiency from three ridge widths using different materials; (2)...

The effects of Al–Mg wire replacing Al–Cu on the microstructure, microhardness and tensile properties 2219 aluminum alloy tungsten inert gas (TIG)-welded joints were studied. Comparing with wire, capping welds can be strengthened by introduction Mg-containing strengthening phase hardness significantly improved. However, for both solidification cracks caused inappropriate control alloying element content continuous brittle phases at grain boundaries around weld zone (WZ) result in reduced...

Agriculture production in study areas benefits from the use of ridge‐furrow rainwater harvesting (RFRH) to supplement rainfall absence irrigation imported sources. However, it is necessary select suitable fodder plants for with RFRH this climate. In paper, 10 treatments (3 ridge widths × 3 ridge‐mulching materials + flat planting [FP] as control) a complete random design were applied 3‐yr field experiment alfalfa ( Medicago sativa L.) and oat Avena production, respectively. Ridges mulched...
