TLDR
The use of the fallout radionuclide (137)Cs to document medium-term soil redistribution rates offers a means of overcoming many of the limitations associated with traditional approaches, and demonstrated statistically significant relationships between some soil properties and the soil redistribution rate, but for most properties there was no significant relationship.About:

Using 137Cs technique to quantify soil erosion and deposition rates in an agricultural catchment in the black soil region, Northeast China
TL;DR: In this article, Wang et al. measured 61 sampling points collected within a 28.5 ha agricultural catchment in the black soil region of Northeast China were used to establish the magnitude and spatial pattern of soil redistribution rates as well as sediment budget within the catchment.

Topographic metric predictions of soil redistribution and organic carbon in Iowa cropland fields
TL;DR: In this paper, the authors examined impacts of sixteen topographic metrics derived from Light Detection and Ranging (LiDAR) data on organic carbon distribution in agricultural fields and developed two topography-based models, stepwise ordinary least square regression (SOLSR) and stepwise principal component regression (SPCR), to simulate spatial patterns of organic carbon (SOC) density and soil redistribution rates.

Relationships of 137Cs inventory with magnetic measures of calcareous soils of hilly region in Iran
TL;DR: The results suggest that further research is needed for the use of magnetic characteristics as an alternative technique in place Cs-137 methodology for calcareous soils in western Iran.

Magnetic susceptibility and Cs-137 inventory variability as influenced by land use change and slope positions in a hilly, semiarid region of west-central Iran
TL;DR: In this article, the authors explored the slope position and land use change effects on the variability in magnetic susceptibility and 137Cs inventory as the soil redistribution indicators in a hilly semiarid calcareous area in Iran.

Soil degradation by erosion
TL;DR: In this paper, the impact of soil erosion on crop yield, productivity, and soil quality is investigated, and it is shown that erosion-induced losses on crop yields are scale-dependent because of the compensatory beneficial effects on yields from depositional sites, and technology dependent because of masking effects of input such as fertilizers and irrigation.

Improved Models for Estimating Soil Erosion Rates from Cesium-137 Measurements
D. E. Walling,Q. He +1 more
TL;DR: In this paper, an improved model for estimating water-and tillage-induced soil redistribution in both cultivated and undisturbed soils is proposed. But, the model is limited by several limitations and uncertainties, such as time-dependent fallout input, initial distribution within the surface layer, post-depositional redistribution resulting from mechanical, physical, chemical, and biological processes operating in the soil system and the grain size selectivity associated with soil erosion and sediment transport processes.

Comparative advantages and limitations of the fallout radionuclides 137Cs, 210Pbex and 7Be for assessing soil erosion and sedimentation
TL;DR: This paper aims to review the advantages and limitations of each of the three FRNs and to identify key knowledge gaps linked to their use, and guidelines for selecting the most appropriate FRN and associated approach are provided.
