Soil organic matter content and nutrient turnover in thin Black Oxbow soils after intensive conservation management
Cultivation and frequent fallowing has a significant impact on soil organic matter (SOM) concentration and soil bulk density. Conservation tillage systems, such as direct seeding, minimize mixing and disturbance of the ...
Methane emissions from waterlogged soils
Developing simplified synergistic relationships to model topsoil erosion and crop yield
Topsoil is highly enriched with organic matter, which provides a valuable source of plant nutrients as well as a favorable rooting environment. Over time, erosion processes selectively remove the organic matter-rich fine ...
Phosphorus forms in soil amended with meat and bone meal ash and dried distillers grain ash
Biogas production from organic materials via gasification process also generates a valuable byproduct of ash. Ash contains the original nutrient present in organic materials, except carbon, nitrogen and sulfur that are ...
Impact of grazing native prairie on soil and plant nutrients in southwestern Saskatchewan
A reduction in the sage grouse population could be a result of the export of nutrients from the long term grazing management that has been in place in grassland ecosystems such as southwestern Saskatchewan for the past ...
Application of a mustard root bioassy to assess phytotoxicity of Group 2 herbicides
Group 2 herbicides exhibit high bioactivity at low concentrations in soil and may persist into the next growing season causing crop injury. A bioassay that is suitable for the detection of a range of Group 2 herbicides was ...
Post-emergence application of liquid swine manure in east central Saskatchewan
In early 1997, the Prairie Protein Action Committee was established and one of its objectives was to identify ways to meet the increasing demand for wheat with specific protein quality and quantity (Fowler et al. 1998). ...
Soil and crop response to injected liquid swine manure on two Gray Luvisols
Intensive livestock production is increasing in western Canada, and so is the need to dispose of the manure produced. In the last six years or so, the Saskatchewan Centre for Soil Research at the University of Saskatchewan ...
Enzymatic activity and microbial biomass in soil amended with biofuel processing byproducts
Plant essential nutrient and carbon contained in byproducts associated with biofuel production have increased their value as soil organic amendments. These byproducts include wet distillers grain, and thin stillage from ...
