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.

Return to Earthworms can save the world.
