Effects of agriculture on earthworm populations,ge during cultivation, to the loss of the insulating layer of vegetation, or to a decreased supply of food as the organic matter content gradually decreases. Many workers have considered that these differences are largely due to mechanical damage during cultivation. When old grassland is ploughed, t

Zicsi (1954) reported such damage to various crops, and Edwards (unpublished) noted that earthworms destroyed a large part of a lettuce crop
