Fall 2023
Grasslands cover 30% of the planet’s terrestrial surface and provide habitat and forage for livestock and wildlife. In addition, grasslands have the potential to mitigate climate change by sequestering substantial amounts of carbon (C) in the soil. However, the ability of grassland soils to...

Fall 2023
Biochar is a stabilized carbon with porous structure that can be used as an economical adsorbent for wastewater treatment. Since there are numerous types of biochars, it is important to understand how biochar characteristics influence adsorption performance by selecting or customizing biochars...

Fall 2015
Pine sawdust biochars produced at 300 and 550 °C with and without steam activation were assessed for its sorption capacity for phosphate and copper (Cu (II)) in aqueous solutions using batch sorption experiments, including isotherm and kinetic studies. This study implied that pine sawdust...

Afforestation and stand age affected soil respiration and net ecosystem productivity in hybrid poplar plantations in central Alberta, Canada
DownloadFall 2010
Afforestation and stand development can significantly affect soil respiration and net ecosystem productivity (NEP). I studied 1) the effects of afforestation on NEP by comparing cropland previously planted to barley (on a barley-barley-alfalfa-alfalfa-alfalfa rotation) and that converted to a...

Application of manure from cattle fed with different diets affects soil properties and greenhouse gas emissions
DownloadSpring 2019
Cattle production contributes the largest portion of livestock agricultural greenhouse gas (GHG) emissions in Canada mostly in the form of methane (CH4). Efforts to reduce CH4 emissions have led to modification of diet composition for livestock, resulting in a corresponding change in manure...

Spring 2010
Land use and land use change strongly influence the carbon (C) dynamics within ecosystems. This study quantified four aspects of land use and land use change effects: 1) ecosystem C stocks and distribution; 2) soil respiration; 3) soil C mineralization; and 4) net ecosystem productivity. Land use...

Effects of long-term nitrogen and sulfur deposition on soil microbial communities and soil properties in the Athabasca oil sands region in northern Alberta, Canada
DownloadFall 2016
Intensified oil sands activities have resulted in elevated levels of nitrogen (N) and sulfur (S) deposition in the mixedwood boreal forest in the Athabasca oil sands region (AOSR) of northern Alberta, Canada. The deposition of N and S can affect the surrounding ecosystem and it is important to...

Extracellular enzyme activity, greenhouse gas emissions and soil microbial communities responses to drought and defoliation in northern temperate grasslands
DownloadFall 2023
Grassland ecosystems cover more than 40% of the global land area and provide many ecological goods and services, therefore, it is important to sustain these terrestrial ecosystems. One of the ecological services they provide is their potential to act as a carbon (C) sink. However, northern...

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 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...
