Impact of Production System and Nutrient Addition on Grain Quality in Long-term Rotation Studies in Western Canada, 2000
Two alternative management projects are currently being conducted in western Canada, using cropping diversity and level of external inputs to assess crop production. Both of these projects were designed to provide a baseline from which to assess the impact of how diversity of crops grown in rotation, and the inputs used can impact production, pest populations, soil quality and economic returns. Grain samples have been saved for each of these projects; however, little or no evaluation of samples has been carried out. Flax grain samples from the University of Manitoba study were collected from the end of the first and second four-year rotation cycle. Wheat grain and straw samples were collected from year four after the end of the first cycle of the Agriculture and Agri-Food Canada study. These samples have been submitted for a complete micro and macronutrient assessment with the goal of determining how management input is influencing crop nutrient uptake. MB-13
