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 Full Text: Non-industrial wood ash chemistry and its biogeochemical effects on sugar maple (Acer saccharum, Marsh.) in three central Ontario sugar-bushes A Thesis Submitted to the Committee on the Graduate Studies in Partial Fulfillment of the Requirements for the …

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 Full Text: Trace Metal Geochemistry of Peatlands A thesis submitted to the Committee of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY Peterborough, Ontario, Canada …

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 Full Text: Effects of Intensive Agriculture on Stream Nutrient Export in EastCentral Ontario, Canada A thesis submitted to the Committee on Graduate studies in partial fulfilment of the thesis requirements for the degree of Master of Science in the Faculty of Arts …
