Nitrous Oxide Emission Reduction in an Annual Cropping System as a function of Nitrification Inhibitors and Liquid Manure Injection Timings
DownloadFall 2016
Nitrous oxide (N2O) contributes to global warming and ozone depletion. Two-thirds of the global N2O emissions are derived from agricultural soils receiving manure or fertilizer applications. The goal of this study was to identify and develop management practices that can decrease N2O emissions...

Nitrous Oxide Emissions in Southern Alberta Croplands in response to Nitrogen Rates, Fertigation and Moisture
DownloadSpring 2018
Irrigated agriculture is an important source of global food supply due to its high production intensity; however, it is also a large user of water and nitrogen fertilizer, and therefore, a potential large contributor of N2O emissions. This study explores the viability of fertigation, a method of...

Non-Native Plant Management And Restoration Of Foothills Fescue Grassland In Waterton Lakes National Park, Alberta
DownloadFall 2013
Non-native plants are a formidable barrier to native grassland restoration. Foothills fescue prairie restoration was investigated at three southern Alberta sites through reduction of non-native plant cover by steaming, herbicide and mowing; by increasing native plant cover with transplanting,...

NURSERY FERTILIZATION AND UNDERSTORY COMPETITION AFFECT SEEDLING GROWTH IN OIL SANDS RECLAIMED SOILS IN ALBERTA
DownloadSpring 2017
Revegetation in the oil sands mining areas in northern Alberta has often been difficult because of high mortality and slow growth of planted seedlings on reclaimed soils. Growth of the planted seedlings is limited by low nutrient and water availability in the soil on reclaimed sites. Management...

Nutrient distribution in sandy soils along a forest productivity gradient in the Athabasca Oil Sands Region, Alberta, Canada
DownloadFall 2016
Brunisolic soils developed on coarse textured (sandy loam to sand) deposits comprise a significant portion of the land currently being disturbed by surface mining in the Athabasca Oil Sands Region of Alberta, Canada. The goals of this study were to determine (i) how the physical properties of...

Nutrient Loading of Aspen, Jack Pine and White Spruce Seedlings for Potential Out-planting in Oil Sands Reclamation
DownloadFall 2012
Low nutrient availability and competing vegetation are some of the issues facing tree crop establishment for land reclamation in the oil sands region. A possible solution to both problems is to load seedlings with nutrients while they are in the nursery. Here, I report on results from a research...

Oat, pea, and canola intercropping: An investigation of the agronomic benefits and underlying biological mechanisms of a multi-crop forage system
DownloadSpring 2022
Oat, pea, and canola intercropping can provide benefits in terms of beef cattle forage as it can provide stable biomass and nutritional yield. Two underlying mechanisms were examined as potential explanations to its stability: 1) plant water use efficiency, and 2) arbuscular mycorrhizal fungi...

Occupancy and Impacts of the Northern Crayfish (Faxonius virilis) in Tributaries of the North Saskatchewan River Basin
DownloadFall 2021
Invasive species are the second greatest threat to biodiversity globally. Crayfish are especially robust invaders due to their omnivorous feeding behavior and ability to compete both directly and indirectly with native species. In the North Saskatchewan River (NSR) basin, the Northern Crayfish...

Occurrence and fate of pharmaceuticals and personal care products (PPCPs) at a northern wastewater treatment facility
DownloadSpring 2017
The occurrence of pharmaceutical and personal care products (PPCPs) in municipal wastewater treatment plants (WWTP) is an emerging environmental issue. Among other concerns, aquatic invertebrates sampled from WWTP have measurable concentrations of PPCPs, which have been found to cause adverse...
