Buried wood effects on soil nutrient supply and microbial activity in different oil sands reclamation soils in Northern Alberta
DownloadSpring 2022
Manchola Rojas, Laura Alejandra
Buried wood is an important component of natural and anthropogenic soils, yet it remains severely understudied. Nutrient immobilization as a response to wood addition in soils raises concerns from oil sands reclamation practitioners since the clear and grub procedures prior to soil salvaging tend...

Characterization of Soil Spatial Heterogeneity and Improvement of Capping Materials for Oil Sands Mine Reclamation
DownloadFall 2018
Surface mining in the Athabasca Oil Sands Region (AOSR), Alberta, Canada creates a large-scale ecosystem disturbance requiring ‘land reclamation’. Mining approvals require that land reclamation returns the sites to an equivalent land capability class, but this goal has proven challenging to...

Spring 2018
The development and application of quantitative soil quality assessment (SQA) concepts involve calibrating soil quality indicators (SQI), such as soil organic carbon (SOC), to soil management goals such as yield or biomass productivity to create soil quality-scoring functions (SQF). Currently,...

The Impact of Reclamation and Vegetation Removal on Compositional and Functional Attributes of Soil Microbial Communities in the Athabasca Oil Sands Region
DownloadSpring 2021
Large-scale mining for oil extraction in the boreal forests of Northern Alberta has led to a disturbance footprint of ~ 900 km2 of land; which, under regulations from the government of Alberta, must be reclaimed to equivalent land capabilities using soil materials salvaged and conserved during...
