The use of soil in colliery spoil reclamation

, : The use of soil in colliery spoil reclamation. Soil Use & Management. 9(4): 148-152

Field trials measured the benefits of using soil in the reclamation of colliery spoil. Increasing the thickness of the soil cover increased grass yield, particularly on a site with potentially acidic spoil materials. Mixing soil with the underlying spoil increased slightly compared to using the same amount of soil as a cover. From these and earlier results, we conclude that: the use of soil as a cover is essential on sites with acidic, or potentially acidic, spoil; to be effective in the short-term, the thickness of soil can be as little as 15 cm; the use of soil on sites with non-acidic spoil is beneficial in terms of physical conditions, such as improved water-holding capacity and better root penetration; the benefits of incorporating the soil on such sites are probably insufficient to justify the additional effort involved.
