How much nitrogen can farmers really cut?

Manitoba fertilizer trials search for the sweet spot where farmers can cut nitrogen rates, with a nitrification inhibitor, without harm to yield

Manitoba fertilizer trials seek a sweet spot where farmers can cut nitrogen rates, with a nitrification inhibitor, without hurting yield and with fewer 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

Project to take high-level look at ag emissions

A CBC tower will be used to monitor nitrous oxide on the Prairies

Glacier FarmMedia — A group of researchers, policy makers and producer organizations is repurposing part of a CBC transmission tower to get data on agriculture’s greenhouse gas emissions. The tower at Yorkton, Sask., will be fitted with sensors to measure agricultural nitrous oxide emissions 100 metres above the ground. The group, dubbed CanN20net, held its […] Read more
