How winter canola could profit Illinois farmers, improve sustainability
URBANA, Ill. — A new simulation study from the University of Illinois Urbana-Champaign suggests winter canola could be profitable and environmentally beneficial if added to a conventional corn-soy rotation in the U.S. Midwest. “In the six months between fall harvest and spring planting, the land is just sitting there. Cover crops help protect the soil, but they don’t typically generate revenue. A winter oilseed crop like canola could protect the soil and generate farm revenue by providing a feedstock for sustainable fuels,” said senior study author D.K. Lee, professor in the Department of Crop Sciences, part of the College of Agricultural, Consumer and Environmental Sciences at Illinois. The study simulated winter canola in a double-cropping system in Illinois. The research team used a model called DayCent to simulate the crop’s performance under real environmental conditions measured between 2019 and 2024. The model compared a conventional corn-soy rotation (scenario 0) with a corn-canola-soy rotation under four nitrogen fertilizer scenarios: scenario 1, with no added nitrogen during canola growth; scenario 2, with 112 kg nitrogen per hectare (kg N/ha) applied in spring; scenario 3, with 28 kg N/ha applied in fall and 112 kg N/ha in spring; and scenario 4, with 56...
