Agronomic Evaluation of Novel Green Manures for Organic Grain Production in Eastern Canada
(2015)Green manures (GrM) are used to meet organic crop-N needs. Productivity and N-accumulation of three spring-planted full-season GrM in Nova Scotia and two in Québec were compared. Hairy vetch-oats accumulated 123-292 kg ... -
Food and Yard Waste Compost as a Nutrient Source for Corn Production
(2012-04-10)Utilizing food and yard waste (FYW) compost for plant production requires determination of application rates that support crop production, improve soil properties and avoid excessive nutrient build-up. An 88 day incubation ... -
IMPACT OF VARIABLE RATE SPLIT FERTILIZATION ON CROP PRODUCTION AND ENVIRONMENTAL CONTAMINATION IN WILD BLUEBERRY
(2014-04-04)The heavy rainfall, gentle to severe topography with high proportion of bare spots, and weed patches emphasize the need of variable rate split (VRS) fertilization in wild blueberry. Two commercial fields were selected in ... -
Multi-scale assessment and simulation of sediment biogeochemical cycles in coastal areas: implications for ecosystem functioning and provision of services
(2017-08-29)Marine coastal sediments and associated communities provide benefits to humans through natural processes such as nitrate removal via denitrification (prevention or mitigation of eutrophication), burial of toxic substances ... -
Nitrogen and Oxygen Isotope Effects of Nitrite Oxidation in Various Species of Nitrite-oxidizing Bacteria
(2020-12-18)Bioavailable nitrogen is a limiting nutrient in many parts of the ocean. Nitrite oxidation produces biologically available nitrate, which in turn can help regulate primary production and the absorption of carbon dioxide ... -
Quantification Of Gross Nitrogen Transformation Rates Within A Conventional Potato Rotation Using Stable Isotopes
(2012-12-13)This study used the isotope pool dilution method to estimate gross rates of mineralization, nitrification, NH4+ and NO3- consumption, and denitrification emissions over two growing seasons within a conventional barley-red ... -
Whole Farm Nutrient Budgets of Two Dairy Farms in Atlantic Canada
(2011-12-05)Whole farm nutrient budgets (WFNB) enable producers to link dairy herd management with traditional field nutrient management plans. The objective of this study was to calculate WFNBs of nitrogen, phosphorus, and potassium ...
