The slope length
effect was most pronounced for the aggregate sizes
smaller than 0.05 mm. The more sandy the original
soil was, the more clay was found in the total soil
loss and in the smaller aggregates in that soil loss.
Moreover the slope length effect was most pronounced
for the smallest aggregates. The aggregate
sizes displayed different relationships between soil
loss and slope length. For the short slope lengths
used in this study we can assume that mainly interrill
erosion occurred.
