Designing biochar to enhance forest productivity

加拿大林业部门正在积极寻求发展“绿色”经济的途径。湖首大学森林实验室和Alterna Biocarbon之间的合作项目将研究生物炭（来自木材和/或农业废弃物）在增加森林生产力的同时以稳定的形式封存碳的潜力。这种可再生资源与高效碳化技术的结合有可能促成碳负循环——也就是说，储存的碳多于释放的碳。在热带高度风化的土壤中被称为“preta”，添加生物炭已被证明可以通过改善土壤来促进植物生长。特别是保留和释放

Canada's forest sector is actively seeking ways to develop the "green" economy. This collaborative project between Lakehead University FoReST Laboratory and Alterna Biocarbon will investigate the potential for biochar (from wood and/or agricultural waste) to augment forest productivity while simultaneously sequestering carbon in a stable form. This combination of a renewable resource with a highly efficient carbonization technology has the potential to contribute to a carbon negative cycle - that is, to store more carbon than it releases. Known as "terra preta" in highly weathered soils of the tropics, the addition of biochar has been shown to enhance vegetative growth by improvement of the soil. Specifically, retention and release
