Description	The aim of the work was to compare production of N2O during composting with different temperature regimes, different aeration intensity and different input mixture. Two different mixtures of organic material with three levels of aeration underwent composting process in two temperature regimes. Mixture A contained woodchips, separated pig slurry, fresh grass and tree leaves, mixture B contained woodchips, tree leaves, grass and urea to optimize C:N ratio. Mixture with urea additive showed high N2O production when kept under low temperature, when the same mixture was kept in higher temperature, production of N2O were 3 fold lower. However mixture without urea addition kept in high temperature shows almost no N2O production. Production of N2O was highest when nitrates concentration increased. Production of N2O is perhaps by-products of nitrification, but also other pathways may contribute.
