    Abstract: <p>Agricultural land application of biosolids recycles nutrients and organic matter to the soil, however the effect of treatment process on nutrient availability requires further research for better nutrient management. This study examined the bioavailability of nitrogen (N) and phosphorus (P) in alkaline treated biosolids (TB) when amended into three different soils. Despite a 45%… more

    Soil mineralizable nitrogen as an indicator of soil nitrogen supply for grain corn in southwestern Ontario

    Name(s): Creator (cre): Stoeckli, Jessica, Thesis advisor (ths): Sharifi, Mehdi, Degree committee member (dgc): Eimers, Catherine, Degree committee member (dgc): Ponce-Hernandez, Raul, Degree granting institution (dgg): Trent University
    Abstract: <p>Soil mineralizable nitrogen (N) is the main component of soil N supply in humid temperate regions and should be considered in N fertilizer recommendations. The objectives of this study were to determine the potentially mineralizable N parameters, and improve N fertilizer recommendations by evaluating a suite of soil N tests in southwestern Ontario. The study was conducted over the 2013… more
