Two field sites located in the northern region of the North American Great Plains were examined to investigate the contributions of water and tillage erosion towards total soil erosion in topographically complex landscapes (hummocky and undulating landscapes). Results indicated that both water and tillage erosion contributed substantially to total erosion in the undulating landscape while tillage erosion dominated in the hummocky landscape. The patterns of water, tillage and total soil erosion…

Variability of Soil Properties in Eroded Agricultural Landscape

Erosion strongly influences the soil properties and affects the intra-field variation of nutrients not only in steep young morainic landscapes but also on gentle slopes of old-glacial landscapes. The

Tillage erosion: the principles, controlling factors and main implications for future research

Tillage erosion is one of the major contributors to landscape evolution in hummocky agricultural landscapes. This paper summarizes the available data describing tillage erosion caused by hand-held or

Understanding the role of water and tillage erosion from 239+240Pu tracer measurements using inverse modelling

Abstract. Soil redistribution on arable land is a major threat for a sustainable use of soil resources. The majority of soil redistribution studies focus on water erosion, while wind and tillage

Assessment of soil erosion by compensatory hoeing tillage in a purple soil

This study explores the role of a traditional tillage method, i.e., compensatory hoeing, for sustainable agro-ecosystem management in the hilly areas of the Chongqing municipality, south-western

The effects of three micro-catchment practices on erosion and runoff dynamics for a typical soil slope on the Loess Plateau of China

Abstract: Three micro-catchment measures that are named fish-scale pits (FSPs), artificial digging (AD), and contour plowing (CP) for soil erosion prevention are widely used in the Loess Plateau. To

Evaluating the effects of changes in landscape structure on soil erosion by water and tillage

Landscape structure, or the spatial organization of different land units, has an impact on erosion and sedimentation on agricultural land. However, current erosion models emphasize the temporal, and

Identifying spatial patterns of erosion for use in precision conservation

ABSTRACT: The application of site-specific conservation practices requires knowledge of spatial patterns in fields. This study evaluated two methods of delineating soil erosion patterns in a central

Variation in soil properties and crop yield across an eroded prairie landscape

Intensive tillage moves large quantities of soil, resulting in a pattern of soil redistribution where topsoil is depleted from convex slope positions and deposited in concave positions. In these

Landscape segmentation modeling in agricultural fields: Correlating soil pH to herbicide persistence

ABSTRACT: There is increasing recognition that spatial variability in soils occurs across the landscape within a field and that differential management practices are warranted. Differences in

Although approximately 1.3 million ha of mixed Solonetzic – Chernozemic landscapes are cultivated in Saskatchewan, little information is available on the effects that agriculture has had on the
