The aims of this study were to (1) experimentally quantify the relationship between mineral N input and N2O emissions from denitrification, (2) describe the time course of N2O fluxes resulting in N inputs, and (3) find whether there exists an upper limit of the amount of nitrogen escaping the soil in the form of N2O. The study site was a grassland used as a cattle overwintering area. It was amended with KNO3 and glucose corresponding to 10-1,500 kg N and C per hectare, covering the range of nutrient inputs occurring in real field conditions. Using manual permanent chambers, N2O fluxes from the soil were monitored for several days after the amendments.
