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土壤的可行性。 冶炼作业产生的酸化土壤的修复。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Collège之间 博雷亚尔。在受控温室环境中，来自上述工业伙伴的木灰被发现 对土壤养分和林木苗木生长有显著的正效应。该计划的目的是 目前的研究是通过田间试验来证实温室研究的结果，以确定 受百年采矿活动影响的土壤上木灰的有效性。嘉能可-萨德伯里 综合镍业务(萨德伯里INO)已经加入了合作伙伴关系，希望木灰可以 在其采矿属性上使用。这一结果将为这家跨国矿业公司提供一个廉价的 和环境友好的替代石灰和肥料，以减少土壤酸度和改善土壤 营养素。与此同时，EACOM木材公司将看到3个好处：(A)经验证据支持 它们的灰分在酸化的矿区上的效果，(B)一种将木灰固结用于田间应用的过程 以及(C)关于将木灰添加到其锯木厂生产的副产品清单中的可行性的市场研究 安大略省和魁北克省。最后，Boréal学院和Cégep学院的教授和学生 Abitibi-Témiscamingue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.
