Just a few years ago it seemed like Canada’s farmers couldn’t get peas into the ground fast enough, but they’re now falling out of favor. Pea plantings will probably decline to a seven-year low this spring, while lentil acreage drops by 27 percent, according to the nation’s agriculture ministry. Sowings will decline as farmers swap land for wheat and canola, the Canadian-made oilseed that’s used in everything from salad dressing to french fries. It’s a classic crop boom and bust. Since 2014, pea and lentil acres surged across the country amid rising demand for the vegetarian staples and as farmers enjoyed record prices for the legumes. But that swell of production quickly led to a global glut and sent prices tumbling. Now countries such as India, the world’s biggest consumer, are imposing tariffs on imports to try to shore up markets for domestic suppliers. Regina, Saskatchewan-based AGT Food & Ingredients Inc., one of the top exporters of pulse crops, has slumped more than 40 percent in the past 12 months.
