DESCRIPTION:PhD Oral Defense of Patrick Brassard\, Department of Bioresourc
 e Engineering\n\nLike every sector of activity\, the agriculture sector wi
 ll need to develop and apply solutions to mitigate greenhouse gas (GHG) em
 issions in order to limit the temperature increase to 1.5 °C above pre-ind
 ustrial levels\, which was an objective stated in the Paris agreement in 2
 015. In the province of Quebec (Canada)\, agricultural soils generate 26.9
 % of the total emissions in the agricultural sector. Most of them are in t
 he form of N2O emissions resulting from the nitrification and denitrificat
 ion of mineral N. Research studies demonstrated that biochar amendment to 
 soil can contribute to the reduction of GHG emissions\, and particularly N
 2O. Biochar is the solid product of the thermochemical decomposition of bi
 omass at moderate temperatures (350 – 700 °C) under oxygen-limiting condit
 ions\, which is generally achieved through pyrolysis. About 50% of the car
 bon (C) in biomass is found in biochar after pyrolysis\, and most of this 
 C would be sequestered in soil for more than 1000 years according to many 
 researchers. However\, not all biochars are created equal as their propert
 ies will depend on both biomass properties and pyrolysis operating paramet
 ers. Therefore\, biochar with specific properties should be designed for a
  specific application. Soil properties and environmental conditions will a
 lso have an impact on the effect of biochar in soil.\n\nThe main objective
  of this doctoral research project was to produce engineered biochars with
  specific properties and to evaluate their potential to be used as a tool 
 to mitigate climate change.\n\n\nEveryone in the McGill community is welco
 me to attend a PhD oral defense. Please join us in celebrating the accompl
 ishments of our PhD candidates.\n
