A characterization of the controls of the nitrogen and oxygen isotope ratios of biologically-produced nitrous oxide and nitrate in soils
(University of Waterloo, 2011-08-02)Nitrous oxide (N₂O) is a potent greenhouse gas, an important driver of climate change, and its concentration in the atmosphere is rising at an unprecedented rate. Agriculture is the leading contributor of all the anthropogenic ... -
Impacts of Dredging and Brush Cutting of Paired Agricultural Drainage Ditches on GHG Emissions and Nutrient Filtration Capacity
(University of Waterloo, 2023-01-04)Agriculture provides many beneficial and essential ecosystem services. Along with these beneficial services, the conversion of natural ecosystems into heavily modified agricultural ecosystems is also a source of ... -
Multi-decade comparison of groundwater nitrate in the southern Nottawasaga River Watershed
(University of Waterloo, 2016-08-25)The Nottawasaga River Watershed is host to the Lake Algonquin Sand Aquifer (LASA), an unconfined aquifer that consists of glaciolacustrine sands and provides water supply to rural residents, for household use, and for ... -
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 ... -
NO3- and N2O at the Strawberry Creek Catchment: tracing sources and processes using stable isotopes
(University of Waterloo, 2008-08-26)Nitrate (NO3) contamination in agricultural watersheds is a widespread problem that threatens local drinking supplies and downstream ecology. Dual isotopes of NO3- (d15N and d18O) have been successfully used to identify ...
