“…Thus, cultivated sites did not exhibit any evidence of significant tillage mixing, and it was not possible to apply a standard conversion model for cultivated soils. Consequently, a conversion model developed for undisturbed sites had to be used to calculate the soil erosion rates, which seemingly provided reliable results [24].…”

“…Isotopes of beryllium (meteoric 10 Be), plutonium ( 239+240 Pu) and caesium ( 137 Cs) are widely used in Earth sciences to reconstruct, for example, Earth's palaeomagnetic field [4][5][6], snow palaeoaccumulation rates [7], seafloor sedimentation rates [8] and denudation rates [9] and to determine the age of fluvial terraces [10][11][12], evaluate seawater exchange cycles [13] and long-distance Asian dust transport [14], among several other processes. More recently, these isotopic tools have been used to investigate soil erosion processes in various environments, such as grasslands and forests of the European Alps or the Rocky Mountains [15][16][17][18][19][20][21], in arable lands, forests and grasslands of tropical and subtropical areas and the wet-dry tropics [22][23][24][25][26], in forested mountainous regions [21,27], forests and arable lands under continental Mediterranean climates [28][29][30][31], in moraine landscapes used as farmlands and forests [2,[32][33][34][35], in loess regions that are dominated by agriculture [36][37][38][39][40] or in post-fire forests and deserts areas [41,42].…”

Meteoric 10Be, 137Cs and 239+240Pu as Tracers of Long- and Medium-Term Soil Erosion—A Review

et al. 2022

Isotopes of meteoric 10Be, 137Cs, 239+240Pu have been proposed as a soil redistribution tracer and applied worldwide as an alternative method to classical field-related techniques (e.g., sediment traps). Meteoric 10Be provides information about long-term soil redistribution rates (millennia), while 137Cs and 239+240Pu give medium-term rates (decades). A significant progress in developing new models and approaches for the calculation of erosion rates has been made; thus, we provide a global review (n = 59) of research articles to present these three isotopes (meteoric 10Be, 239+240Pu and 137Cs) as soil erosion markers in different environments and under different land-use types. Understanding the dynamics and behaviours of isotopes in the soil environment is crucial to determine their usefulness as soil erosion tracers; thus, we discuss the chemical–physical behaviour of meteoric 10Be, 137Cs and 239+240Pu in soils. The application of these isotopes sometimes has strong limitations, and we give suggestions on how to overcome them or how to adapt them to a given situation. This review also shows where these isotopic methods can potentially be applied in the future. A lack in knowledge about soil redistribution rates exists particularly in loess-dominated areas where the tillage system has changed or in areas with strong wind erosion.

“…Caesium-137 is the most commonly used radionuclide and its handling is well established (MOURI et al, 2014;PORTO;WALLING, 2015;VELASCO et al, 2018;IAEA, 1998;GOLOSOV et al, 2017;WALLING AND HE, 1998;1999).

“…As Yoshimory et al, 2003 points out, 7 Be decays to 7 Li emitting a gamma ray of 477.8 keV, through which it can be easily measured by gamma ray spectrometry. This radionuclide has been recognized as a useful tool in the study and description of environmental processes, such as transit and residence time of aerosols in the troposphere, the speed of aerosols' deposition (DUEÑAS et al, 2005), imprisonment by vegetation, transit and the residence time of sediment in rivers as well as evaluation of erosive surface processes (VELASCO et al, 2018;WALLING et al, 1999b;SCHULLER et al, 2006). In the latter two cases, beryllium-7's short half-life offers a way to identify newly deposited sediment.…”

Monitoring geological and hydrological phenomena presents a great environmental and financial interest for which several natural and artificial radioisotopes have been used. In this work, 7Be was used to determine soil erosion in three areas: a soybean culture, following in the direction of a topographical slope, one perpendicular to the slope’s direction and another one on bare land. The samples were analyzed by gamma ray spectrometry. The relaxation mass constant (h0) was 4.71±0.36 similar to other researches. The bare soil had the largest soil erosion out of all the three studied areas, while the soil redistribution rate was lower when soybeans were cultivated perpendicular to the slope. The technique was useful to be able to see the soil path during erosion.

Quantifying soil redistribution rates, including both erosion and deposition, is critical for understanding erosion processes, landscape evolution, land management strategies, and the carbon cycle. In the Northeast Pacific coastal temperate rainforest, the interaction of perhumid climate and dense coniferous forest tends to form Spodosols which are soils characterized by a subsurface accumulation of organic matter and iron and aluminum oxides, across a range of contrasting lithologies. Deep Spodosols are frequently found on steep backslopes (up to 60%) of colluvial deposits, where shallower soils would typically be expected. We hypothesized that deep Spodosols in Southeast Alaska indicate slope stability, exhibiting negligible soil redistribution rates and stable surfaces regardless of the lithology. Our objective was to quantify soil redistribution rates for Spodosols formed on steep slopes across a range of lithologies in hilly and mountainous areas of Juneau, AK. We used 239+240Pu isotopes to quantify soil erosion and deposition rates in Spodosols formed on colluvial deposits from tonalite, slate, metavolcanic rock, and phyllite. 239+240Pu measurements revealed negligible soil redistribution rates for all studied pedons, ranging from erosion rates of 0.51 t/ha/year to deposition rates up to 0.43 t/ha/year. No difference was detected between the hill and mountain landforms, further supporting the idea that Spodosols could indicate slope stability over decadal timescales across the region. Understanding the resilience of Spodosols to erosion processes in varied lithologies and landforms on steep slopes is paramount for making informed decisions regarding sustainable land use, landslide risk mitigation, and effective carbon sequestration strategies.
