Previous mining activities such as ore roasting beds and smelters has had a noticeable impact on the acidity and nutrients in the city of Greater Sudbury's soils particularly in locations nearest to the activity. In 2009, the results of a soil study showed that the most test soils had been moderately to severely impacted. The impact included poor fertility, low nutrient balance, and limited capacity for water retention. Interestingly, test soils that were treated with a liming agent designed to augment the levels of pH within the soil contained lower levels of toxicity and metals. The environmental impact has led to several re-greening initiatives but none have included the use of wood ash. The use of wood ash to inject nutrients and reduce soil acidity is a frequent practice in Europe, most notably in the Scandinavian countries (Brunner et al., 2004).The general objective within the present investigation is to determine the efficacy of readily-available wood ash from one power generation company on foliage and soil found in a greenhouse setting. Chemical analysis will be conducted and should the ash be deemed useful, the company will have added a viable co-product through this value-added initiative.

以前的采矿活动，如矿石焙烧床和冶炼厂，对大萨德伯里市土壤的酸度和养分产生了显着影响，特别是在距离活动最近的地点。 2009年，一项土壤研究结果表明，大多数测试土壤都受到了中度到严重的影响。其影响包括生育力差、营养平衡低以及保水能力有限。有趣的是，用旨在提高土壤 pH 值的石灰剂处理过的测试土壤中的毒性和金属含量较低。环境影响导致了多项重新绿化举措，但没有一项举措包括使用木灰。在欧洲，特别是在斯堪的纳维亚国家，使用木灰注入养分和降低土壤酸度是一种常见的做法（Brunner 等人，2004 年）。本次调查的总体目标是确定现成的木灰的功效。一家发电公司的木灰残留在温室环境中的树叶和土壤上。将进行化学分析，如果认为灰烬有用，公司将通过这一增值计划添加可行的副产品。
