Name(s): Creator (cre): Ranasinghe, Oshadhi Ruwanthika, Thesis advisor (ths): Thompson, Karen, Degree committee member (dgc): Eimers, Catherine, Degree committee member (dgc): Dang, Huy, Degree granting institution (dgg): Trent University
Abstract: <p>In Ontario, farmers commonly use a MZ (Maize (Zea mays L.))-SB (Soybean (Glycine max))/WW (Winter wheat (Triticum aestivum)) – CC (mixed cover crop) rotation to maximize economic benefits. This study aimed to investigate the short-term impacts of the crop rotation phases and their associated management practices in this diversified cash crop rotation on soil health and the abundance of… more

Name(s): Creator (cre): Hiltz, Clinton David, Thesis advisor (ths): Aherne, Julian, Degree committee member (dgc): Helm, Paul, Degree committee member (dgc): Metcalfe, Chris, Degree committee member (dgc): Dang, Huy, Degree granting institution (dgg): Trent University
Abstract: <p>This thesis determined the temporal dynamics of microplastics in the biosolid and final effluent of a WWTP for one year (October 2020–September 2021). The WWTP exported 354.1 ± 24.7 billion microplastic particles, or 296.7 ± 39.4 kg of microplastics; of this, 85.7% of counts and 86.6% of mass was exported via biosolids. As such, microplastic loads in biosolids need to be reduced before… more

Abstract: <p>Dissolved inorganic carbon in drainage waters is a direct measurement of carbon dioxide (CO2) removal from enhanced rock weathering (ERW) in soils. In this study, square metre scale field experiments (2021–2023) were conducted in Peterborough Ontario, Canada, each amended with kimberlite residues from Gahcho Kué Diamond Mine (Northwest Territories, Canada) or olivine powder at high… more
