. The soil conditions both before and after restoring opencast sites and their effect on drainage and crop growth are discussed both in general and with specific reference to the site concerned. Both drainage treatments showed a benefit over the undrained control, although no extra benefit was observed from drains at 20‐m spacing with mole drains and subsoiling compared to drains at 40‐m spacing with mole drains. Subsoiling reduced bulk density and increased surface infiltration rates, but improvements to the soil brought about by subsoiling were short‐lived.
