Sandy soil poses challenges for reclamation professionals due to wind erosion, low organic matter content and low water holding capacity. In Canada's boreal forest, reclamation efforts involving sandy soil are further exacerbated by length of growing season and impact of soil disturbance on saprobic and symbiotic elements of the microbial community. Disruption of this living component reduces the soil's ability to decompose litter and translocate nutrients, minerals, and water to newly established plants. For Alberta and Saskatchewan's oil sands sector, these challenges have contributed to mixed success regarding reclamation efforts while engendering significant expenditures in manpower and equipment. From 2015 to 2017, the oil industry experienced a 49% decrease in capital investments and a $19 billion loss in revenue. Advances in reclamation science leading to improved reforestation success appear more in demand than ever, particularly if they can be achieved at reduced cost. Saskatchewan Polytechnic, in association with Reclaimit Ltd., aims to address this need through a series of research trials to identify soil treatments and amendments that offer enhanced prospects for jack pine (Pinus banksiana) establishment and growth. The research will focus on organic content, microbial community development, and plant growth. The proposed setting for this research will be Saskatchewan Polytechnic's Hanin Creek Education and Research Facility (HCEARF) in the Mid-boreal Upland Ecoregion of north central Saskatchewan. This ecological setting is consistent with many oil sands developments in Saskatchewan and Alberta. Our objective is to identify the ideal soil treatment for ecologically sustainable forest reclamation on coarse-textured soils. Results will be compared to reference ecosystems. These advancements in reclamation science should prove beneficial for carbon sequestration as well.

沙质土壤由于风侵蚀，低有机物含量和低水持有能力而对填海专业人员构成挑战。在加拿大的北方森林中，涉及沙质土壤的开垦工作进一步加剧了生长季节的长度以及土壤干扰对微生物群落的腐生和共生元素的影响。这种生活成分的破坏降低了土壤将垃圾分解和流动养分，矿物质和水的能力。对于艾伯塔省和萨斯喀彻温省的油砂领域，这些挑战在填海工作方面取得了不同的成功，同时在人力和设备方面付出了巨大的支出。 从2015年到2017年，石油行业的资本投资下降了49％，收入亏损了190亿美元。 填海科学的进步导致改善造林成功似乎比以往任何时候都更多，尤其是如果可以降低成本来实现它们。萨斯喀彻温省理工学院与Recaimit Ltd.联合使用，旨在通过一系列的研究试验来满足这一需求，以确定土壤处理和修正案，从而为杰克·派恩（Pinus Banksiana）机构和增长提供了增强的前景。该研究将重点关注有机含量，微生物社区发展和植物生长。这项研究的拟议环境将是萨斯喀彻温省理工学院的Hanin Creek教育与研究设施（HCEARF），萨斯喀彻温省北部中部山地生态区。这种生态环境与萨斯喀彻温省和艾伯塔省的许多油砂开发项目一致。我们的目标是确定在粗纹理土壤上生态可持续森林填海的理想土壤处理。结果将与参考生态系统进行比较。填海科学方面的这些进步也应证明有益于碳的隔离。
