Longer growing season allows more Canadian farmers to grow corn

Corn is the most common grain in the U.S., with its production historically concentrated in a Midwestern region stretching from the Ohio River valley to Nebraska and trailing off in northern Minnesota. It had been ungrowable in the fertile farmland of Canadas breadbasket. That is changing as a warming climate, along with the development of faster-maturing seed varieties, turns the table on food cultivation. The Corn Belt is being pushed north of what was imaginable a generation ago.
Growing seasons on the Canadian prairie have lengthened about two weeks in the past half-century. The mean annual temperature is likely to climb by as much as 5 degrees Fahrenheit in the region by 2050, according to Canadian researchers.
In Canada, that means amber waves of wheat are giving way to green fields of corn. Farmers sowed a record 405,000 acres of corn in Manitoba, Saskatchewan and Alberta last year, double the amount two years earlier and almost eight times what it was 20 years ago. That compares with 95.4 million acres sown in the U.S. last year.
