“Earthworms,” in the words of Edwards (1988), “play a major role in improving and maintaining the fertility, structure, aeration and drainage of agricultural soils.” As noted by Sharpley et al. (1988), for example, “by ingestion and digestion of plant residue and subsequent egestion of cast material, earthworms can redistribute nutrients in a soil and enhance enzyme activity, thereby increasing plant availability of both soil and plant residue nutrients,” as others have also demonstrated.
