Earthworm counts were done last year on cover
crop plots that were established after wheat harvest. These are plots with simple
cover crop mixtures like oats, radish and crimson clover. The number of earthworms
was compared where there was cover crop to the no cover crop check. The results
varied across the plot but there was always more earthworms in the cover crop
treatments. Anywhere from slightly more to two to ten times as many earthworms
in the cover crop area.
