“…In Germany, however, no erosion study using the radiotracer method has been published to date, although erosion is regarded as a major threat to soils (Auerswald and Schmidt 1986;Frede and Dabbert 1998). In a few years' time, it will not be possible to use 137 Cs as a retrospective tracer in regions like southern Bavaria with a substantial deposition of Chernobylderived 137 Cs, both because the two sources of 137 Cs can no longer be distinguished and because total 137 Cs is not suitable for replacing Cs (for details see Schimmack et al 2001). Therefore, we have recently started to investigate the potential of 239+240 Pu from global fallout (Pu) as a tracer of soil movement in a steep field (inclination 20%) near Scheyern in Bavaria.…”

“…Plutonium was also deposited by the Chernobyl fallout, but in Germany the amount of this fraction is negligible (<1% of the total inventory, Hötzl et al 1987). In an earlier paper (Schimmack et al 2001), we compared the activity patterns of Cs and Pu. In the present paper, erosion and deposition rates are calculated from these inventories and compared with estimates of model calculations including tillage erosion.…”

In the near future, the use of 137Cs from global fallout (Cs) as a tracer for erosion studies will no longer be possible in areas with a substantial deposition of Chernobyl-derived 137Cs. Therefore, we have used (239+240)Pu from global fallout (Pu) as a tracer as well as 137Cs in order to determine long-term soil redistribution rates for an agricultural field (inclination about 20%, area approx. 3 ha) in Scheyern, Bavaria. The mean erosion and deposition rates derived from Cs were -37 and +52 t x ha(-1) x year(-1), respectively; those from Pu were -32 and +39 t x ha(-1) x year(-1). We found no statistical difference between the means obtained by the two tracers. In contrast to Pu, however, the rates obtained by Cs were not accurate enough to assure the presence of a net soil redistribution. Modeling of soil translocation in the field by water and tillage erosion resulted in estimates which were in reasonable agreement with the rates derived from Pu.

“…40 km north of Munich (11 v 27 0 E, 48 v 30 0 N). Several erosionbased radiotracer studies have been performed there during the past years (Weigand et al, 1998;Auerswald and Schimmack, 2000;Schimmack et al, 2001Schimmack et al, , 2002 as well as other studies measuring recent erosion on an event and watershed scale Fiener and Auerswald, 2003). Thus, the spatial distribution of the RIP can be compared to the results of these earlier studies including soil mapping and soil redistribution rates determined using 137 Cs and 239þ240 Pu from global fallout as radiotracers.…”

Two principal groups of processes shape mass fluxes from and into a soil: vertical profile development and lateral soil redistribution. Periods having predominantly progressive soil forming processes (soil profile development) alternate with periods having predominantly regressive processes (erosion). As a result, short‐term soil redistribution – years to decades – can differ substantially from long‐term soil redistribution; i.e. centuries to millennia. However, the quantification of these processes is difficult and consequently their rates are poorly understood. To assess the competing roles of erosion and deposition we determined short‐ and long‐term soil redistribution rates in a formerly glaciated area of the Uckermark, northeast Germany. We compared short‐term erosion or accumulation rates using plutonium‐239 and ‐240 (239+240Pu) and long‐term rates using both in situ and meteoric cosmogenic beryllium‐10 (10Be). Three characteristic process domains have been analysed in detail: a flat landscape position having no erosion/deposition, an erosion‐dominated mid‐slope, and a deposition‐dominated lower‐slope site. We show that the short‐term mass erosion and accumulation rates are about one order of magnitude higher than long‐term redistribution rates. Both, in situ and meteoric 10Be provide comparable results. Depth functions, and therefore not only an average value of the topsoil, give the most meaningful rates. The long‐term soil redistribution rates were in the range of −2.1 t ha‐1 yr‐1 (erosion) and +0.26 t ha‐1 yr‐1 (accumulation) whereas the short‐term erosion rates indicated strong erosion of up to 25 t ha‐1 yr‐1 and accumulation of 7.6 t ha‐1 yr‐1. Our multi‐isotope method identifies periods of erosion and deposition, confirming the ‘time‐split approach’ of distinct different phases (progressive/regressive) in soil evolution. With such an approach, temporally‐changing processes can be disentangled, which allows the identification of both the dimensions of and the increase in soil erosion due to human influence. © 2019 John Wiley & Sons, Ltd.
