Abstract
The numbers and weights of earthworms were measured in the top 20 cm of soil in a long-term monoculture corn (Zea mays L.) experiment involving different tillage treatments. There was a marked seasonal trend in earthworm concentrations, with number and weight of worms being higher in spring and autumn than in summer. Spring tillage reduced earthworm numbers; however, the incorporation of surface residues per se had no effect.
