Greenhouse Gas Emissions from Potato Production in British Columbia's Lower Fraser Valley
MSc Research Project | 2018 - 2020

Key Findings
1. Greenhouse Gas Emissions and Potato Yield under Different N Fertilizer Application Rates
Yield increased with N fertilizer rate at the productive field, however a cost-benefit analysis showed that the increase in yield between the 90 and 120 kg N ha⁻¹ treatments did not significantly outweigh the additional fertilizer costs or potential residual N losses to the environment.
2. Effects of Fertilizer Rate on Soil Nitrogen Dynamics
Nitrogen fertilizer rate resulted in significant differences for plant available nitrogen, and plant carbon and nitrogen concentrations. With higher urea application rates, there were greater soil nitrate concentrations at the end of the growing season which are susceptible to leaching to groundwater sources or N2O emissions through denitrification processes.
