The focus of this study is to examine the risk and return trade-offs for various crop rotations and tillage systems. The geographic area represented in this study will be that contained within four soil, and five climatic zones within the Province of Alberta. The predominant crops grown in these...
An Annotated Bibliography of Crop Rotation and Tillage Literature With Special Emphasis on the Canadian PrairiesDownload
This annotated bibliography was compiled during research project 94-092 funded by Farming for the Future. Some of these references were cited in the research and others simply provided background information. The references shown here are not meant to be a comprehensive listing of literature...
An interview based survey of farm landowners in the south east corner of Saskatchewan was undertaken to evaluate the provision of wildlife habitat by agriculture. Producers were asked to provide management information regarding a piece of their land that was managed as a unit. Within the past ten...
Greenhouse Gas Emissions Following Tillage Reversal on a Black Chernozem and a Gray Luvisol in AlbertaDownload
Agricultural soils under long-term no till management have been well known to sequester atmospheric carbon in soil organic matter and to reduce emissions of greenhouse gases. Our study aimed at quantifying CO2 and N2O emissions from Black Chernozems and Gray Luvisols managed under long-term (~ 30...
Herbicide resistance in wild oat to current herbicidal mechanisms of action is widespread across western Canada. Pyroxasulfone is a soil-applied very long chain fatty acid inhibitor (Group 15/K3) that has recently been registered in Canada and may become a future tool in managing this resistance,...
Scale-dependent covariance of soil physical properties above and below a soil horizon interface: Pedogenic versus anthropogenic influences on total porosityDownload
The basic unit of soil – the pedon – is described as the minimum, three-dimensional unit of soil representative of the variability of soil horizon dimensions and morphology. Pedogenic processes responsible for soil horizon and soil profile formation are primarily hydrologic in nature. The...
Tillage Reversal and Nitrogen Fertilization Affected Greenhouse Gas Emissions and Soil Carbon Stability Differently in a Black Chernozem and a Gray LuvisolDownload
Improving soil carbon (C) sequestration through land management practices is of great interest due to concerns over global climate change caused by increased atmospheric greenhouse gas (GHG) concentrations. Soil disturbance by conventional tillage (CT) generally accelerates soil organic carbon...
