2.1  mm2 - cm2: interrill and rill erosion
2.2  m2: -
2.6 Other scale or processes investigated: -
3 WIND EROSION
4 MASS MOVEMENTS
5 TILLAGE EROSION
Spatial scale considered: Field scale. Experiments concern the measurement of the downslope movement of soil by tillage using tracers.
6 TEMPORAL SCALE OF EXPERIMENTS
Number of time units (below) the experiments cover;

Experiments mainly carried out to investigate mechanisms, independent of spatial scale.
