Model outputs include daily fluxes of various N-gas species (e.g., N 2 O, NO x, N 2); daily CO 2 flux from heterotrophic soil respiration; soil organic C and N; net primary productivity; daily water and nitrate (NO 3) leaching, and other ecosystem parameters. Daycent has been tested using data from various native and managed systems.
