Abstract: <p>Ontario grain corn is highly valuable, accounting for 60% of Canada's total corn output. Grain producers are increasingly interested in including cover crops (CCs) in their cropping systems, but they have concerns regarding successful CC establishment and potential adverse competitive effects on corn yield and nutrient status. One option to improve the success of CC establishment is… more

Legume species, nitrogen rate and arbuscular mycorrhizal fungi inoculation effects on crop biomass and nitrogen requirement in a corn-legume system

Name(s): Creator (cre): Pei, Chengyin, Thesis advisor (ths): Sharifi, Mehdi, Degree committee member (dgc): Saville, Barry, Degree granting institution (dgg): Trent University
Abstract: <p>Interseeding legume cover crops in grain corn may improve the environmental sustainability of corn production system in Southern Ontario. This study aimed to assess the effects of legume species, nitrogen (N) fertilizer rate and arbuscular mycorrhizal fungi (AMF) inoculation on biomass and N requirement in a corn-legume system. Corn was grown with red clover (RCl), microclover (MCl),… more

Nitrogen and phosphorus bioavailability in soil amended with alkaline stabilized biosolids

Name(s): Creator (cre): Halloran, Samantha, Thesis advisor (ths): Sharifi, Mehdi, Degree committee member (dgc): Metcalfe, Chris, Degree committee member (dgc): Price, Gordon, Degree granting institution (dgg): Trent University
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
