Abstract:
... Soil erosion rates in cultivated areas have intensified during the last decades leading to both on and off-site problems for farmers and rural communities. Furthermore, soil redistribution processes play an important role in sediment and carbon storage within, and exports from, cultivated catchments. This study focuses on the impact of land consolidation and changes in landscape structure on mediu ...

Water Erosion Prediction Project; agricultural land; highlands; land cover; land use change; mulches; overland flow; rivers; runoff; sediment yield; sediments; soil; watershed hydrology; watersheds; Minnesota
Abstract:
... Sediment delivery from the Le Sueur River watershed is a major concern in the turbidity-impaired Minnesota River. As part of a broader effort to develop a sediment budget for the Le Sueur River, this study implemented a process-based watershed hydrology and upland erosion model, Water Erosion Prediction Project (WEPP), to simulate hydrology and sediment dynamics in several land-use/land-cover scen ...

Subject:
Chrysopogon zizanioides; agricultural land; bulk density; cassava; continuous cropping; corn; eroded soils; grain yield; growing season; humid zones; intercropping; planting; rain; runoff; soil depth; soil structure; soil water content; spatial distribution; tropics; water content; Nigeria
Abstract:
... Large losses of soil usually occur under continuous cropping systems in the tropics owing to high rainfall erosivity coupled with predominately weak soil structure. Vetiver grass (V. nigritiana) planted at intervals across slopes could check erosion losses and allow meaningful cultivation of the alleys between vetiver hedgerows. Between 2004 and 2007, studies were conducted at Ibadan in the humid ...

Subject:
agricultural land; bulk density; carbon sequestration; earthworms; environmental protection; heathlands; microbial activity; sandy soils; soil biological properties; soil quality; soil structure; topsoil; Netherlands
Abstract:
... We studied the effect of topsoil removal, a nature management technique used in The Netherlands and other countries in North Europe to restore heathland vegetation. Sandy soils under original heathland vegetation were compared with sites that were transformed to farmland in 1950 and sites where after the transformation topsoil removal took place in the 1990s. All soils were sandy and acidic. Topso ...

Abstract:
... The distribution and storage of soil organic carbon serve as basic data for the study of soil productivity, soil hydrological properties, and the balance among carbon-based greenhouse gases. In this study, the organic carbon storage and density distribution characteristics of the soil in the Zhifanggou catchment on the Loess Plateau were studied based on field investigations, laboratory measuremen ...

Abstract:
... Understanding the process of agricultural land expansion and its impact on soil properties is crucial for land management and environmental health. A desert–oasis ecotone is typically located between an oasis at the lower reach of inland rivers and neighboring desert in arid regions, and acts as an interactive zone between irrigated farmland and the natural desert ecosystem. The arid region of nor ...
