The federal government’s plan to reduce greenhouse gas emissions from nitrogen fertilizer is generating heat with farmers and some industry groups. Karen Proud, president and CEO of Fertilizer Canada, says the goal of achieving a 30 per cent reduction may be achievable, but is the government’s timeline realistic and at what cost does it come to farmers? Plus, Mario Tenuta, research chair in 4R nutrient management and professor with the University of Manitoba, discusses fertilizer emission research and finding the balance between implementing 4R practices and crop yields.
