A survey of pyrogenic carbon in Kootenay National Park burned soils, and its positive effect on the establishment of pine-fungal ectomycorrhizal symbiosis
DownloadSpring 2020
Wildfire is a natural disturbance in Rocky Mountain forest landscapes. Fire plays an important role in maintaining stand structure, woody debris consumption, and soil nutrient cycling. Fire exclusion in these ecosystems has expanded forest cover, altered stand structures, and allowed...

Assessment of Perennial Cereals in Central Alberta: Environmental Performance and Productivity
DownloadFall 2023
Despite their paramount importance, modern, high-input agroecosystems used for annual grain production are often characterized as degraded systems with substantial greenhouse gas (GHG) emissions, namely nitrous oxide (N2O), a GHG 273x more potent than carbon dioxide (CO2) on a mass basis....

Development of an Extraction Method for Estimating Phytoaccessible Fractions of Bromacil and Tebuthiuron
DownloadFall 2022
Bromacil and tebuthiuron are herbicides used from the 1960s to 1990s on industrial sites to control vegetation. Approximately 61,750 sites are considered contaminated when comparing total herbicide concentrations (estimated by 99 percent methanol extraction) against Alberta’s remediation...

The effects of biochar-manure on crop yield, greenhouse gases, and organic matter stability in an Orthic Gray Luvisol
DownloadSpring 2023
Cattle production contributes to the largest portion of livestock agricultural greenhouse gas (GHG) emissions in Canada, mainly in the form of methane (CH4). Therefore, there is interest in the modification of livestock diet composition to try and reduce the emission of CH4, resulting in a...
