The base includes a plurality of generally parallel spaced apart support elements, the support elements being spaced apart at a distance sufficient to support the material within the chamber during the treatment process and enable extraction of the treated material through the spaces between the support elements during a harvesting process. There is also disclosed a harvesting device comprising a plurality of extraction elements which are adapted to project through the spaces between the support elements to dislodge and extract the treated material through the base. The apparatus and harvesting device is particularly useful for removing worm casting in vermiculture.
