Description: While much has been reported on nitrous oxide, carbon dioxide and methane measurements from intensively cultivated, agricultural soils during the growing season, very little has been reported on emissions of greenhouse gases during the non-growing season period. In the North Atlantic Region of Canada-US, the soils are often frozen from about late November to mid April-early May. During this freeze/thaw period, the soils often have residual nitrogen, carried over from the previous growing season, and could be a significant source of N2O during the spring snowmelt period. This presentation presents estimates of gas emissions in this freeze-thaw period, and makes comparisons with growing season emissions.
