Abstract

Five soil cover box systems varying in area were used to measure the N₂O emissions from four arable soils. The covered area of the systems ranged from 78 to 576000 cm². The observed N₂O emission rates were approximately log-normal distributed. The greatest influence of variation of N₂O emission rates could be attributed to the factor sampling date/time. The different soil cover box systems were assessed by comparing measured mean N₂O releases, their time courses and spatial variation. The spatial coefficient of variation of N₂O emission rates decreased logarithmically with an increasing radius of the soil cover box system used.
