A field study about the efficacy of using wood-ash for soil remediation on one mining property in**the Sudbury Basin

本研究旨在探讨利用木灰处理对冶炼作业产生的酸化土壤进行土壤修复的可行性。这项研究是在加拿大自然科学和工程理事会、EACOM木材公司和博莱尔学院**之间完成的一个试点项目之后进行的。在受控温室环境中，来自上述行业伙伴的木灰被发现**对土壤养分和树苗生长具有统计上显著的积极影响。本研究的目的是通过进行实地试验来确定木灰对受一个世纪采矿活动影响的土壤的**有效性，从而证实温室研究的结果。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**用于其采矿资产。这一结果将为这家跨国矿业公司提供一种廉价且环保的替代石灰和化肥的方法，以减少土壤酸度并改善土壤**养分。同时，EACOM木材公司将看到三个好处：(A)支持其灰渣在酸化采矿土地上**功效的经验证据，(B)将木灰整合用于田间应用的过程**，以及(C)对将木灰添加到其位于安大略省和魁北克省的锯木厂生产的副产品清单中的可行性进行的市场研究**。最后，来自Collège Boréal和Cégep**Abitibi-Témiscamingue的教授和学生将受益于提高他们关于一种工业残留物的研究技能。

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.
