Investigation of the effectiveness of locally produced biochar on mine remediation

The growing interest in the application and use of Biochar has contributed to the need to explore different varieties of feedstocks.  Of particular interest are the different methods and techniques used to produce biochar.  Therefore the goal of this project was to investigate the effectiveness of locally produced Biochar in promoting plant growth on soils contaminated during mining operations; this is an enhancement on a previous biochar project: Research Into the Use of Biochar in Yukon Mine Reclamation. 

Project Overview

There were two objectives for this project.  The first was to develop a system to allow for stable, long-term and low-labor intensity site reclamation.  The second objective was to investigate the effectiveness of using feedstock available on-site to provide this remediation.
In conclusion plots that had a combination of biochar and compost performed the best in terms of plant growth within the tailings ponds. This was consistent over all 3 sites.
