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...

Biodiversity of soil arthropods in a native grassland in Alberta, Canada: obscure associations and effects of simulated climate change
DownloadFall 2013
Soils have traditionally been treated as a “black box” due to the challenges of studying this complex medium. The living component of soil consists of a complex network of roots and mostly very small, highly abundant, and extremely diverse group of microbes, protists, and other invertebrates. In...

Boreal forest CO2 exchange and evapotranspiration predicted by nine ecosystem process models: Inter-model comparisons and relationships to field measurements
Download2001
Wofsy, S.C., Frolking, S.E., Wang, S., Clein, J.S., McGuire, A.D., Potter, C.S., Goulden, M.L., Chen, J.M., Grant, R.F., Nikolov, N.T., Amthor, J.S., Kimball, J.S., King, A.W.
Nine ecosystem process models were used to predict CO2 and water vapor exchanges by a 150-year-old black spruce forest in central Canada during 1994-1996 to evaluate and improve the models. Three models had hourly time steps, five had daily time steps, and one had monthly time steps. Model input...

Debris Field Kinetics during the Dynamic Fragmentation of Polyphase Natural Ceramic Blocks: Ejecta Measurements and Damage Modes
Download2013
Hogan, James, Schneider, Markus, Rogers, Robert, Spray, John, Vincent, Gregory
The dynamic fragmentation of coarse and fine grained granitoid blocks during impact has been examined for energies of 1.9 kJ to 3.0 kJ and 2.7 kJ to 6.8 kJ, respectively. A particle tracking algorithm was developed to measure ejecta size and velocity at the rear of the target for a horizontal...

Cannon, K.R., Finlayson, N.M., Landsburg, S.
A study was initiated in 1988 to evaluate the effects of pipeline construction on soil compaction in the province of Alberta. The pipelines were located throughout Alberta on a number of different soils and were constructed using various techniques. Cone penetration resistance of soils (soil...

Effect of Pipeline Construction on Soil Strengths of Soil Horizons in Alberta: 1990 Final report
Download1991
Finlayson, N.M., Landsburg, S., Cannon, K.R.
This study was initiated in 1988 to evaluate the effects of pipeline construction on soil strengths of various soils in the province of Alberta. The pipelines were scattered throughout Alberta on a number of different soils and were constructed using various techniques. At each of the fifteen...

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...
