Investigation of water repellency and critical water content in undisturbed and reclaimed soils from the Athabasca Oil Sands Region of Alberta, Canada
Ecosystems are disturbed to extract synthetic crude oil from the Athabasca Oil Sands Region (AOSR) in northern Alberta, Canada. Successful reclamation of mined oil sands sites depends on maximizing water storage and ...
Evaluation of Preferential Flow Processes in Reclamation Soil Covers
To predict the effectiveness of land reclamation, it is important to understand how water and solutes are transported within reconstructed landscapes. The objective of this study was to examine the influence of preferential ...
Soil conditions and early crop growth after repeated manure applications
Development of the swine and cattle industries has led to an increase of manure application to agricultural lands in Saskatchewan. Studies have been conducted to determine the nutrient benefits of swine manure application. ...
Characterizing soil organic nitrogen using advanced molecular analytical techniques
Soil organic N (SON) comprises 90% of all N in surface soils, yet as much as half remains in forms which are chemically unknown or, at best, poorly understood. Analytical methods such has pyrolysis field-ionization mass ...
Spatial and temporal patterns of nitrous oxide and their relationship to soil water and soil properties
Soil N2O flux is sensitive to soil moisture content and soil temperature, which are in turn sensitive to changes in climate and topography. Thus, N2O flux measurements exhibit a high degree of spatial and temporal ...
Microbial Regulation of Soil Greenhouse Gas Emissions in a Non-Bloat Legume Grazing System
Cattle pastures are a source of greenhouse gas (GHG) emissions, including enteric methane from ruminating cattle, carbon dioxide (CO2), and nitrous oxide (N2O) from microbial respiration of soil carbon (C) and nitrogen ...
