- •
Land use changes and runoff affect the distribution of soil nutrients and 137Cs.
- •
Loss of SON, SOC and 137Cs is related to soil loss by water erosion and tillage.
- •
The effect of soil redistribution on SOC dynamics is evidenced in the study field.
- •
Distribution of grain size fractions is linked to SOC, SON and 137Cs patterns.
- •
Reduced tillage practices favor the increase of soil nutrients in topsoils.
