N2O production by fungal denitrification in a semiarid soil

摘要

The increasing nitrous oxide (N2O) concentration in the atmosphere causes concern due to its contribution to global warming. Soils, especially agricultural soils, contribute approximately half of the world's anthropogenic N2O emissions and currently this source of N2O represents 2.4% of the European release of anthropogenic derived greenhouse gasses (GHG). Furthermore, N2O is also directly or indirectly involved in destruction of stratospheric ozone. Modern agriculture must strive to mitigate N2O emissions by cultivated soils.
