This Alliance partnership between the University of Saskatchewan MOST Facility, Sunterra (Canada) Inc., and Okane Consultants Inc. (Okane) is designed to evaluate and test soil amendments for mine covers in cold regions. Mine covers are crucial to mine closure where constructed slopes store and release water to the environment and prevent water and oxygen ingress into waste rock and mine tailings. We will test a suite of new soil amendments as a follow-on to our previous research collaboration with Profile Products, Sunterra (Canada) Inc.'s parent company. This new follow-on work will focus on the effect the amendments have on soil nutrient content and water availability on poor mine cover soil. The evaluation and testing of soil amendments for mine covers is both an economically and environmentally important research topic to Canada. We estimate that in Canada, about $25 million in "demand" and ~$500 million in "risk" exists for mine covers and their life-cycle over the next 10-20 years. This project will test a suite of soil amendments designed to stimulate vegetation growth, limit hillslope erosion risk, and improve hydrological functioning of created mine covers. Following the project's completion, Sunterra will invest in advancing these results in the Canadian mining and reclamation sectors. This research will cover a two-year period and result in the training of a research Technician, a post-doctoral fellow and two Masters of Water Security (MWS) students. Equity, diversity, and inclusion are interwoven into the training plan. McDonnell has a uniquely strong track record of diversity in his lab with 50% female membership (in a field of 28% female participation overall) with high international and ethnic diversity. Current members in the McDonnell lab group hail from Canada, Brazil, Chile, Mexico and China and one of the 3 members who graduated this year was First Nations. Diversity of ideas, backgrounds, genders, and ethnicity is his goal for team building for research excellence-described in his 2016 paper in Science magazine titled "Orchestrating a Powerful Group". Our diversity will aid this partnership and help us answer the pressing questions for our business partners.

萨斯喀彻温大学MOST设施、Sunterra(加拿大)公司和Okane咨询公司(Okane)之间的这一联盟合作伙伴关系旨在评估和测试寒冷地区矿山覆盖的土壤改良剂。矿山覆盖对关闭矿山至关重要，在那里建造的斜坡储存和释放水到环境中，并防止水和氧气进入废石和尾矿。我们将测试一套新的土壤改良剂，作为我们之前与Profile Products，Sunterra(Canada)Inc.的母公司S的研究合作的后续。这项新的后续工作将集中于修正案对贫瘠的矿山覆盖土壤的土壤养分含量和水可获得性的影响。对加拿大来说，评价和测试矿山覆盖物的土壤改良剂是一个经济和环境都很重要的研究课题。我们估计，在加拿大，在未来10-20年内，地雷覆盖物及其生命周期大约存在2500万美元的“需求”和约5亿美元的“风险”。该项目将测试一套土壤改良剂，旨在刺激植被生长，限制山坡侵蚀风险，并改善已创建的矿山覆盖物的水文功能。在该项目完成后，Sunterra将投资于在加拿大采矿和复垦部门推进这些成果。这项研究将为期两年，培训一名研究技术员、一名博士后研究员和两名水安全硕士(MWS)学生。公平、多样性和包容性交织在培训计划中。McDonnell在他的实验室有着独特的多样性记录，50%的女性成员(在女性参与的领域中，女性总参与率为28%)，以及高度的国际和种族多样性。麦克唐奈实验室小组目前的成员来自加拿大、巴西、智利、墨西哥和中国，今年毕业的3名成员之一是原住民。思想、背景、性别和种族的多样性是他为卓越研究而建立团队的目标--他在2016年发表在《科学》杂志上的题为《编排一个强大的团队》的论文中描述了这一点。我们的多样性将有助于这种伙伴关系，并帮助我们回答我们的商业伙伴面临的紧迫问题。
