Abstract:
The last four decades of agricultural production in western Canada have seen a steady upward trend in the area seeded to canola and pulses, a reduction of tillage, and the adoption of herbicide tolerant and hybrid seeds. Market conditions have also shifted. Canola has become the most profitable option in many regions. With the price spikes of 2022, canola gross margins for the average farm in Manitoba reached $291/ha – nearly 50% higher than the return to wheat in the spring of 2022. With higher prices, agronomically preferred rotation choices are challenged, and nutrient application has been increasing. The nutrient demand comes at the same time that the Canadian federal government is suggesting limits on emissions tied to the use of some of these inputs.
The crop years of 2020/21 and 2021/2 exhibited an unprecedented price climb, peak and rapid drop off in the interior prices for Canadian canola. This presentation will explore the details of the domestic and world oilseed market conditions at the start of the period for producers and explore prices shifts through the last two years. These higher prices change the dynamics on optimal nutrient management including crop rotation choices and fertilizer choices. This presentation will explore recent estimates for optimal crop rotations within several regions of Manitoba and then updated these under the new price structure.
