There is concern that acidic minesoils limed to only the 30 cm depth may not provide sufficient root zone for either optimum plant growth or long-term plant establishment. It was shown that agricultural discs, chisel plows (subsoilers) and moldboard plows can incorporate lime efficiency to the 10 to 25 cm minesoil depth. One very large tandem disc having 91 cm diameter blades successfully neutralized acidic minesoil to the 30 cm depth. Tractors mounted rototillers commonly used in agricultural production can efficiently incorporate lime to the 25 cm minesoil depth.
