"The use of biochar as a soil amendment for mine affected soil revegetation was established as a field experiment in 2012. While the objective of the present report is to synthesize data collected over the past two years of the program, some general conclusions and recommendations for further research are also supplied. The field plots were established on three different mine tailings sites within a 100 km radius of Whitehorse, Yukon Territory; the Whitehorse Copper Mine Tailings, Mount Skukum Gold Mine (MSGM) tailings and the Arctic Gold and Silver (AG&S) tailings cover. The tailings and tailings cover present different characteristics but share the same challenge for successful revegetation; mineral soils which do not support plant growth without soil amendments." --from Summary.
