orn’s new appeal to Canada’s prairie farmers is based on two things: climate change and price. Growing seasons in the prairie provinces—which border Minnesota, North Dakota, and Montana—have lengthened about two weeks to up to 120 days in the past half-century. The mean annual temperature is likely to climb by as much as 3C (6F) in the region by 2050, according to Canadian researchers.
A temperate climate and longer growing season are ideal for corn. An acre of farmland produces more corn than wheat, making corn the more profitable grain, while the higher yields drive up land values as well.
Corn has long grown in southern Ontario’s mild climate, but for Canadians to be big players in the crop at a new order of magnitude, they must plant in the vast farmland of the prairie provinces. Farmers planted a record 121,400 hectares (300,000 acres) of corn in Manitoba, Saskatchewan, and Alberta this year.
