    Nitrous oxide (N2O) emissions from grazed pasture soils represent a significant source of atmospheric N2O. Nitrous oxide is produced by transformations of nitrogen from cattle excrements, urine and fertilizers entering the soil. Specific conditions are necessary for emissions of N2O and these emissions are both spatially and temporally highly variable. Spatial, and in some extent temporal variability, is due to the complex effect of nitrogen input, pasture management and environmental conditions (e.g., aeration and water status, pore space and pore size distribution, available carbon and mineral nutrients concentration, pH and other soil chemical properties, as well as microbial communities abundance and diversity) on N2O emissions and all this makes estimation of emissions very difficult.
