The present study is an examination into the viability of using a wood-ash treatment for the purpose of soil**remediation on acidified soils resulting from smelting operations. The study follows a pilot project done**between the Natural Sciences and Engineering Council of Canada, EACOM Timber Corporation, and Collège**Boréal. In a controlled greenhouse setting, wood-ash from the abovementioned industry partner was found to**have statistically significant and positive effects on soil nutrients and tree seedling growth. The purpose of the**present study is to corroborate the results of the greenhouse research by conducting field trials to determine the**effectiveness of the wood-ash on soil affected by a century of mining-related activities. Glencore - Sudbury**Integrated Nickel Operations (Sudbury INO) has joined the partnership with hopes that the wood-ash could be**used on its mining properties. The results will provide the multi-national mining company with an inexpensive**and environmentally friendly alternative to liming and fertilising to reduce soil acidity and improving soil**nutrients. Meanwhile, EACOM Timber Corporation will see 3 benefits: (a) empirical evidence supporting the**efficacy of their ash on acidified mining land, (b) a process to consolidate the wood-ash for field application**and (c) a market study on the viability of adding wood-ash to the list of by-products produced at their sawmills**in Ontario and Québec. Lastly, the professors and students from Collège Boréal and Cégep**Abitibi-Témiscamingue will benefit by enhancing their research skill set about one industrial residue.

本研究是一个检查到的可行性使用木灰处理土壤 ** 修复的目的酸化土壤冶炼操作。这项研究是在加拿大自然科学和工程理事会、EACOM木材公司和Boréal学院之间进行的一个试点项目之后进行的。在受控的温室环境中，发现上述行业合作伙伴的木灰 ** 对土壤养分和树苗生长具有统计学上显著的积极影响。本研究的目的是通过进行实地试验来证实温室研究的结果，以确定木灰对受世纪采矿活动影响的土壤的有效性。嘉能可-萨德伯里 ** 综合镍业务（萨德伯里INO）已加入合作伙伴关系，希望木灰可以 ** 用于其采矿财产。研究结果将为这家跨国矿业公司提供一种廉价、环保的替代方法，以减少土壤酸度和改善土壤养分。与此同时，EACOM木材公司将看到3个好处：（a）经验证据支持他们的灰在酸化采矿土地上的功效，（B）一个巩固木灰现场应用的过程 ** 和（c）一项关于将木灰添加到安大略和魁北克锯木厂生产的副产品清单 ** 的可行性的市场研究。最后，来自Boréal学院和Cégep**Abitibi-Témiscamingue的教授和学生将受益于提高他们对一种工业残留物的研究技能。
