Nitrogen and Sulfur Fertilization Effects on Carbon Sequestration and Greenhouse Gas Emissions in S-deficient Soils
DownloadFall 2016
Depending on management practices, agricultural soils have the potential to be both a source and a sink of greenhouse gases (GHGs). Long-term fertilization and crop rotation management practices are considered to have an impact on carbon (C) sequestration and nitrous oxide (N2O) emissions. Sulfur...

Nitrous Oxide Emission Reduction in an Annual Cropping System as a function of Nitrification Inhibitors and Liquid Manure Injection Timings
DownloadFall 2016
Nitrous oxide (N2O) contributes to global warming and ozone depletion. Two-thirds of the global N2O emissions are derived from agricultural soils receiving manure or fertilizer applications. The goal of this study was to identify and develop management practices that can decrease N2O emissions...

Nitrous Oxide Emissions in Southern Alberta Croplands in response to Nitrogen Rates, Fertigation and Moisture
DownloadSpring 2018
Irrigated agriculture is an important source of global food supply due to its high production intensity; however, it is also a large user of water and nitrogen fertilizer, and therefore, a potential large contributor of N2O emissions. This study explores the viability of fertigation, a method of...
