Determining the viability of salvaged organic peat soil using peat-mineral mixes and surrogate growth species Poa protensis and Lolium multiform

  • Peat-mineral mixes (PMM) have been shown and recommended as a suitable reclamation material when upland boreal forest soil (LFH) is not available or cost-prohibitive. During the construction of some wellsites an engineered pad is constructed above the original peat soils. During the reclamation process activities often allow for a potential cost efficient opportunity to salvage these buried soils. The following experiment used two selected species of grass Poa pratensis and Lolium multiflorum and five different PMM's (20:100, 40:60, 60:40, 80:20 and 100:0). Peat soil was collected from an undisclosed location in which peat soil was buried under an engineered pad. Mineral soil was collected from a vegetated natural area within Parkland County, AB. The experiment was ran for 30 days, upon decommission, data for shoot length, shoot biomass, root bounding and nutrient deficiency. Data was then analyzed using descriptive statistics, t-test, correlational analysis and single factor anova. Results show positive correlation and significant effect for P. pratensis and L. multiflorum, respectively. From this experiment we have identified the possible viability of buried organic peat, and areas of improvement for further study.
