Effects from climate change, adaptions and greenhouse gas reduction at 2050 LCRS - Laboratory for Climatology and Remote Sensing

Short summary
Legacy effects of increased temperature on both nitrogen (N) transformation rates and nitrous oxide (N2O) emissions from permanent temperate grassland soil were evaluated. A new source-partitioning model showed the importance of oxidation of organic N as a source of N2O. Gross organic (and not inorganic) N transformation rates decreased in response to the prior soil warming treatment. This was also reflected in reduced N2O emissions associated with organic N oxidation and denitrification.
