Abstract
Degraded or unproductive soils may require any number of physical, chemical and/or biological steps to bring about rehabilitation. This chapter focuses on a method to encourage the natural engineering qualities of soil dwelling earthworms to assist soil improvement. Twenty years ago, the Earthworm Inoculation Unit (EIU) technique was devised to link cultivation of selected species with direct soil introduction. Results have demonstrated that this technique can have superior outcomes compared with more traditional earthworm inoculation. Trials were mainly conducted on reclaimed land, but results from agro-ecosystems have also been positive. The EIU technique, though shown to be effective, may not have been explored as fully as possible and warrants further exploitation.
