  • Earthworm populations as affected by long-term tillage practices in southern Alberta, Canada
    Clapperton, M. J.; Miller, J. J.; Larney, F. J.; Lindwall, C. W. (Elsevier, 1997)
    This study compared earthworm populations of a dryland wheat-fallow rotation after 25 years of zero tillage or conventional tillage. Significantly more earthworms were found in the zero tillage treatments, leading the authors to conclude that long-term tillage practices have a significant effect on earthworm populations.
