Earthworm ecology in reclaimed opencast coal mining sites in Ohio soil develops on the coal spoils, influenced by soil-forming factors — climate, time, topography, parent material and organisms (Jenny, 1980). Of these factors, topography, parent material and organisms may be controlled during mining and subsequent reclamation.

Thus any investigation is faced with the problem of diversity of age, kind and distribution of organic matter within the soil profile.
