Assessing Greenhouse Gas Sources and Sinks in the Crop Sector: Alberta & Manitoba
by Lana Awada & Cecil Nagy
Measuring and tracking the contribution of farming activities to GHGs is key to reducing environmental impacts in the crop sector. GHG accounting can provide a better understanding of agricultural contributions to GHG emissions, help identify management practices that increase or decrease GHG emissions, and better inform policymakers about the magnitude of the sector’s net GHG emissions, while improving their ability to make prudent decisions in developing and implementing climate policy in agriculture. This report adds to the body of literature helping agriculture meet their sustainability goals.

A Discussion on Permanent Cover Carbon Sequestration for Alberta & Manitoba
by Cecil Nagy
Permanent cover is land that is used for hay production either using alfalfa, alfalfa -grass mix or grass. Most of the hay that is produced is used for beef cattle or dairy production.

The amount of nitrogen fertilizer applied to grass hay land over the life of the stand is not known. Extensive rather than intensive hay production is generally the norm using low levels of crop inputs.
