Characteristics of magnetic susceptibility on cropland and pastureland slopes in an area influenced by both wind and water erosion and implications for soil redistribution patterns

Summary

This 2020 field study employed magnetic susceptibility as a geochemical tracer to characterise soil redistribution on slopes managed as either cropland or pasture, in an environment subject to both wind and water erosion. By comparing magnetic signatures across land uses and slope positions, the authors inferred patterns of soil loss and deposition, offering a non-invasive method to quantify erosion processes. The work contributes to understanding how management type (crop versus pasture) influences the spatial distribution of soil movement in erosion-prone regions.

UK applicability

Magnetic susceptibility tracing methods have potential applicability in UK upland and marginal land studies, particularly in areas where both water and wind erosion affect grassland or arable systems. However, the applicability depends on the specific soil parent material and regional erosion regime of the study area, which may differ from typical UK conditions.

Key measures

Magnetic susceptibility measurements; soil redistribution patterns; cropland versus pastureland slope characteristics; wind and water erosion effects

Outcomes reported

The study examined magnetic susceptibility patterns in soils across cropland and pastureland slopes subject to both wind and water erosion, as a means to trace and quantify soil redistribution processes. The findings are presented as implications for understanding soil movement and erosion patterns in these contrasting land-use systems.
