  abstract = {{A}ssessing the {N}2{O} fluxes balance is a key challenge to estimate the effect of agriculture practices on greenhouse gas production. {N}2{O} fluxes remained difficult to measure on a field scale due to high spatial and temporal variability and usually low concentrations. {O}ur work aimed at (i) characterizing by laboratory measurements soil potential {N}2{O} emissions from nitrification and denitrification and (ii) testing a modelling approach of {N}2{O} emissions that circumvents the problem of discrete measurements for two {B}razilian rainfed rice cropping systems, no-tillage ({NT}) vs. disk tillage ({DT}). {T}his latter approach consisted in the combination of 2 models: a mechanistic water transfer model and a {N}2{O} emission model, namely {PASTIS} and {NOE}. {S}imulations with the {PASTIS} + {NOE} approach showed for both {NT} and {DT} treatments that: (i) the soil emitted low amounts of {N}2{O}, (ii) emissions by denitrification corresponded to short periods of high {N}2{O} emissions (15 times as high as emission by nitrification), (iii) nitrification contributed to ca 35% of the total {N}2{O} emissions at the crop cycle scale, (iv) field {N}2{O} emission measurements corresponded to the low bound of simulated emissions from nitrification.},
