The Efficacy Of Wetland Treatment Systems Used To Treat Runoff Mixtures From Different Landscapes Across Kentucky, Emily Nottingham
The Efficacy Of Wetland Treatment Systems Used To Treat Runoff Mixtures From Different Landscapes Across Kentucky, Emily Nottingham
Theses and Dissertations--Biosystems and Agricultural Engineering
The overarching goal was to improve our understanding of the cumulative effect of increased use and occurrence of commonly detected contaminants of potential concern (CPCs) on nitrogen (N) transformation processes in wetlands. The central hypothesis was that those various mixtures of nutrients and CPCs entering treatment wetlands impact N removal pathways. The first study assessed the current state of the literature on the implications to N removal in wetlands in the presence of pesticides and antibiotics. 181 primary studies were identified. Removal efficiencies for nitrate varied widely across the studies, with CPCs impacting microbial communities. A knowledge gap remains in …

Nanopesticide Influence On Nitrogen Cycling In Soils, Jacob Richardson
Theses and Dissertations--Biosystems and Agricultural Engineering
Nanotechnology has several applications in the agricultural industry, as the small size of nanoparticles and high reactivity enables targeted delivery of pesticides and fertilizers to the intended crop. Copper-based nanopesticides such as Kocide, are proposed as a more efficient method for targeted pest control. Despite the potential benefits of nanopesticides, little is known regarding the transport and implications of nanopesticides under long-term inundation conditions often found in downstream wetlands. Specifically, the impact of nanopesticides on microbial nitrogen processes in wetland environments remains unknown. Therefore, this thesis explores the impact of nanopesticides, specifically Kocide, on microbial nitrogen cycles in agricultural and …
