Nitrous oxide emissions from soils: ‘from the bottle to the model’

摘要: Abstract Since the early 1990s, we have been carrying out experiments on N2O production, emission and sorption from a variety of soils ecosystems. These laboratory studies revealed insights complex process formation in under contrasting conditions. Within Belgium, also carried numerous field to measure situ emissions, using closed chamber technique. The latter allowed us suggest region-specific N2O-N factor (2.66% applied N) for direct soil emissions assess spatial temporal variability emissions. Recently, these data validate an adapted version DNDC process-based model predict agricultural Flemish region. Ultimately, it is our aim develop, based this validated model, scenario analyses future soils.
