    Spatial and Temporal Variation in Peatland Geochemistry in Sudbury, Ontario, Canada

    Year: 2014, 2014
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Pennington, Paul Robert, Thesis advisor (ths): Watmough, Shaun A, Degree committee member (dgc): Sager, Eric, Degree committee member (dgc): Gueguen, Celine, Degree granting institution (dgg): Trent University
    Abstract: <p>The damage to Sudbury's landscape from over a century of smelter and logging activity has been severe and impacts well documented. However, despite their abundance in the region, wetlands have received little attention. Recent studies have identified that nutrient limitation is as much a problem as metal toxicity and highlighted not only the importance of wetlands but also the need… more

    ASSESSING THE IMPACT OF ATMOSPHERIC DEPOSITION AND HARVEST INTENSITY ON SOIL ACIDITY AND NUTRIENT POOLS IN PLANTATION FORESTS

    Year: 2014, 2014
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Johnson, James Anthony, Thesis advisor (ths): Aherne, Julian, Degree committee member (dgc): Watmough, Shaun A, Degree committee member (dgc): Huber, Christian, Degree committee member (dgc): Cummins, Thomas, Degree granting institution (dgg): Trent University
    Abstract: <p>The objective of this thesis was to assess the influence of anthropogenic sulphur (S) and nitrogen (N) deposition, and harvesting on soil acidity and calcium (Ca<super>2+</super>), magnesium (Mg<super>2+</super>), potassium (K<super>+</super>) and N soil pools in plantation forest soils in Ireland. The response to reductions in anthropogenic S… more

    Phosphorus forms and response to changes in pH in acid-sensitive soils on the Precambrian Shield

    Year: 2014, 2014

    Name(s): Creator (cre): Baker, Scott Robert, Thesis advisor (ths): Watmough, Shaun A, Thesis advisor (ths): Eimers, Catherine M, Degree committee member (dgc): Dillon, Peter J, Degree granting institution (dgg): Trent University
    Abstract: <p>Catchment soil acidification has been suggested as a possible mechanism for reducing phosphorus (P) loading to surface waters in North America and northern Europe, but much of the research that has been conducted regarding P immobilization in pH manipulated soils has been performed at high P concentrations (> 130 &#956;M). This study investigated how soil acidity was related to P… more
