Objective
To calculate a residue-induced nitrous oxide (N2O) emission factor for the major pulse crops and wheat grown in Saskatchewan. To provide a side-by-side comparison of biological nitrogen fixation (BNF) and net N2O and CO2 budgets from the major pulse crops (and a wheat control) grown in Saskatchewan. To determine the partitioning of nitrogen (N) and carbon (C) in above- and below-ground residues from different pulses to soil organic matter (SOM) pools. To determine the total contribution (mass balance) of residue-derived N and C into SOM pools and into the biomass growth of a subsequent wheat crop in rotation with the pulses.
