Abstract: 
An artificial neural network (ANN) was used to simulate nitrous oxide (N2O) emissions from an intensive grassland ecosystem in New Zealand. Daily N2O emitted was simulated as a function of six input variables of daily rainfall, soil moisture content and temperature, soil nitrate (NO3-), ammonium (NH4+) and total inorganic nitrogen content. Results showed that the ANN was able to calibrate itself to within +/-0.77% of measured N2O values in the training data set, and within 2.0% of values used in the validation data set. This was well within the range of the calculated uncertainties (CV = 10-43%) of the measured N2O emissions in the field, and demonstrated that ANNs are a viable toot for simulating complex and highly variable biological systems.
