Abstract: <p>Nutrient losses from forest soils caused by decades of acid deposition and intensive tree harvesting have affected tree growth and forest health in North America and Europe. Non-industrial wood ash (NIWA), a substance rich in macronutrients, may be a potential remediation strategy to return lost nutrients to forest. However, the chemical composition of NIWA and its effects on soil and… more

Name(s): Creator (cre): Liu, Freddy Stephen, Thesis advisor (ths): Eimers, Mary MCE, Degree committee member (dgc): Sorichetti, Ryan RJS, Degree committee member (dgc): Watmough, Shaun SW, Degree granting institution (dgg): Trent University
Abstract: <p>Recent agricultural land use change in east-central Ontario, including the expansion of intensive agriculture (corn and soybean crops) and tile drainage (TD) infrastructure, may alter the fluxes of both phosphorus (P) and nitrogen (N) to the Lower Great Lakes. Through intensive monitoring of several sub-watersheds that encompassed a range of row crop and TD extents, this study examined… more

Trace Metal Geochemistry in Peatlands

Name(s): Creator (cre): Gilbert-Parkes, Spencer, Thesis advisor (ths): Watmough, Shaun SW, Degree committee member (dgc): Sager, Eric ES, Degree committee member (dgc): Basiliko, Nathan NB, Degree granting institution (dgg): Trent University
Abstract: <p>Peatlands can be found widely across all latitudes and play a significant role in global cycles within the earth's biosphere. The anoxic conditions in peatlands promotes the accumulation of organic matter through decreased rates of decomposition and the storage of certain elements, which have received contaminant loading over the course of human existence, with significant increases… more
