Science Edition 2023—The nutrient uptake and removal guidelines for crops in Western Canada are updated. Researchers discovered considerable variability in uptake and removal due, in part, to known differences in weather and management. Thus these estimates are to be used as guidelines only, not prescriptions. “Revising the crop nutrient uptake and removal guidelines for Western Canada,” Fran...

Science Edition 2023—On light-textured soils, farmers can greatly reduce nitrous oxide emissions (and ammonia losses) from soil by deep-banding urea or using enhanced efficiency fertilizer (EEF) products. “Optimal source, placement and application timing for yield and reduction of greenhouse gas footprint for canola production on light texture soils,” Mario Tenuta, University of Manitoba SaskCanola, Manitoba Canola Growers...

Science Edition 2023—Primary targets for emissions reductions in Western Canada should be the controls on emissions occurring at spring thaw and enhanced synchronization of nitrogen supply with crop nitrogen demand. “Balancing agronomic and environmental outcomes using enhanced efficiency nitrogen fertilizers,” Richard Farrell and Kate Congreves, University of Saskatchewan. SaskCanola, Saskatchewan Agriculture Development Fund Read the full report...

Science Edition 2023—Evaluation of a commercial nitrogen-fixing bacteria product showed that the bacteria did colonize many of the root and shoot tissues, but most did not show strong evidence of nitrogen fixation. In many cases, the percentage of nitrogen in the plants that were colonized was lower than the control (not inoculated) plants. “Advanced N management for...
