Fig. S8 Crichton 1996. a, b Measured daily fluxes , AN and UR, respectively. Each graph shows actual measurements (solid lines) and modelled values (broken lines), and also the putative emission patterns if emissions had been near-zero between days 138 and 156 (dot-and-dash lines; see text). c Cumulative fluxes, based on these putative emission patterns: AN : solid line; UR: dotted line; modelled: broken line.

Fig. S13 a Modelled seasonal N2O emissions versus seasonal measured emissions from ammonium nitrate (AN)-fertilized sites, with regression and confidence limits. Data (solid triangles) relate to site-seasons from which training data were obtained for determination of thresholds and Nmin trend. Slope of regression line not significantly different from that in Fig 10 (p = 0.065). b Corresponding plot for all site-seasons (excluding Aberystwyth outlier), whether used for training data (triangles) or only for modelling (circles); regression line for the combined data: Y=1.031X + 3.529; R2 = 0.674, p<0.001.
