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

本研究是一个检查到的可行性，使用木灰处理的目的，土壤 对冶炼作业造成的酸化土壤进行补救。这项研究是在一个试点项目完成后进行的。 加拿大自然科学和工程理事会、EACOM木材公司和学院之间 博雷尔。在受控温室环境中，发现来自上述行业合作伙伴的木灰 对土壤养分和苗木生长有显著的正效应。的目的 目前的研究是通过进行田间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）加入了合作伙伴关系，希望木灰可以 用于采矿业。结果将为跨国矿业公司提供一个廉价的 环境友好的替代石灰和施肥，以减少土壤酸度和改善土壤 营养素同时，EACOM木材公司将看到3个好处：（a）经验证据支持 它们的灰对酸化矿区的功效，（B）固结木灰用于现场应用的方法 及（c）就将木灰加入其锯木厂生产的副产品清单的可行性进行市场研究 在安大略和魁北克。最后，Boréal学院和Cégep学院的教授和学生们 Abitibi-Témiscamingue将通过提高他们对一种工业残留物的研究技能而受益。

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.
