Characterization of Reclamation Material Stockpiles

The purpose of this study was to evaluate the quality of stockpiled reclamation soil at Albian Sands Energy Inc., focusing on how physical and chemical properties vary with depth and location. Researchers assessed two peat-mineral stockpiles by collecting soil samples on a grid using a drilling unit, analyzing factors such as pH, moisture, organic matter, and nutrient content. Sampling reached depths of up to 9 meters, with particular attention to temperature, frost depth, and microbial activity.

Soil quality in stockpiled reclamation material varied significantly with depth, particularly in terms of temperature, pH, moisture, and nutrient content. Deeper layers tended to remain frozen, limiting microbial activity and decomposition, while surface layers showed signs of nitrogen leaching and elevated C:N ratios. Soil pH increased due to the mixing of calcareous subsoil during stockpile construction, and moisture levels were highest below the surface, likely due to reduced evaporation.
