General comments This study quantifies soil redistribution due to both water and tillage erosion processes in a 4.2-ha catchment (corresponding to one single field) located in an intensively cultivated region of Northeastern Germany. To reach this goal, Pu-239+240 inventory measurements have been conducted (and interpolated) and an inverse modelling approach (based on the SPEROS-Pu conceptual model) has been undertaken. Overall, the study was well designed (through a nice nested sampling approach with five densified sub-grids). In total, soil cores were collected at 219 locations (including 10 detailed depth profiles sampled at different topographic locations C1
