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.

Cutting the nitrous oxide emissions without losing yields

Better nitrogen management promises to both protect crop yields and reduce greenhouse gas emissions from fertilizer; new research looks to verify how much difference it actually makes

Rethinking nitrogen efficiency

Tracking nitrogen with stable isotopes offers surprising insights into fertilizer uptake, loss, and management strategies

Understanding how much nitrogen actually gets taken up by plants is key to improving efficiency—both for profitability and sustainability.
