Researchers at Agriculture and Agri-Food Canada (AAFC) at Lethbridge, Lacombe and Beaverlodge are looking at how to improve cropping efficiencies while lowering nitrous oxide emissions that contribute to greenhouse gases. The trial incorporates several components in an effort to see how nitrogen rates, coated urea, crop cultivar and herbicide rates interact.

“We're trying to answer several questions with the trial. We want to see if we are under-fertilizing new high yielding crops, like hybrid canola and competitive, high yielding barley,” explains research scientist Bob Blackshaw at Lethbridge, who is spearheading the AAFC research along with fellow scientist Xiying Hao. “Nitrogen recommendations were developed for older varieties, but now with the higher producing cultivars, maybe we aren't fertilizing as high as we should be.”
