Abstract
Result from modeling studies on N{sub 2}O emissions using the EXPERT-N model are compared with a limited set of measured N{sub 2}O emission data collected at a Saskatchewan site from 1993 to 1995 under a canola-winter wheat crop rotation. Model simulations were also compared against those predicted by the denitrification-decomposition (DNDC) model. While both models yielded similar results, the comparison between modelled and measured emissions must be considered uncertain due to the limited number of field observations made in any given simulation year (about 20), and the lack of a complete input data set. Comparison of EXPERT-N and DNDC results indicate that EXPERT-N is more closely coupled with high soil moisture content then DNDC. 12 refs., 2 figs.
