Lower nitrogen rates in dry beans could pay off for farmers

Manitoba trials test whether farmers can apply less nitrogen to dry beans without losing yield, despite their typically poor nitrogen-fixing capacity

Manitoba research is testing whether reduced nitrogen fertilizer in dry beans can maintain yields while cutting costs and lowering greenhouse gas emissions.
