Impact of Winter Soil Processes on Nutrient Leaching in Cold Region Agroecosystems
(University of Waterloo, 2021-02-25)High-latitude cold regions are warming more than twice as fast as the rest of the planet, with the greatest warming occurring during the winter. Warmer winters are associated with shorter periods of snow cover, resulting ... -
Nitrous oxide and nitrate in the Grand River, Ontario: Sources, production pathways and predictability
(University of Waterloo, 2013-12-13)The increased use of synthetic nitrogen fertilizers since the early 1900s has resulted in greater food production but also problems with nitrogen pollution in freshwaters. Nitrate (NO3-) is a common pollutant in rivers and ... -
Nitrous Oxide Production in the Grand River, Ontario, Canada: New Insights from Stable Isotope Analysis of Dissolved Nitrous Oxide
(University of Waterloo, 2008-10-07)Nitrous oxide (N₂O) is a powerful greenhouse gas, and its atmospheric concentration is increasing dramatically. N₂O is produced through the microbially-mediated processes of nitrification and denitrification. Since these ...
