Determine physiological, agronomic, and soil-focused metrics of canola NUE among varieties. Examine the relationships between NUE metrics. Differentiate the contributions of fertilizer vs. soil-derived nitrogen sources to uptake using 15N-stable isotope tracing. Determine whether varieties with high plant-based NUE also have high N fertilizer recovery. Determine soil nitrogen fluxes within the growing season. Quantify yield-scaled nitrous oxide emissions.
