Abstract
Sediment in runoff from soil boxes subjected to rainfall simulation (to test the effects of ground cover, subsurface compaction and freezing on interrill erosion of three Prince Edward Island soils) was separated into size classes (fractions) by sieving. The individual and cumulative masses of the fractions, their percentage and enrichment relative to the matrix (uneroded) soil were analyzed to determine treatment effects. Although soil type had no effect on the total sediment eroded, the masses of fractions of less than 0.420 mm were significantly different, with loam producing 68% more of the finest fraction (< 0.075 mm) than sandy loam. All three soils showed enrichment only of this finest fraction. Ground cover, subsurface compaction and freezing treatment significantly affected the masses of the total sediment and the separate fractions.
