Abstract

Soil flux measurements of nitrous oxide and methane have been carried out at a grassland site between August 2006 and July 2007. Eight static chambers and a GC-FID-ECD system have been used for sampling and determination, respectively. Mean soil emission of nitrous oxide is 0.15 kg N ha -1 yr -1 that is 4-5 times lower than measured in an earlier period (2002-2004). Methane flux is negligible due to the unfavourable soil parameters. Measured methane fluxes were below the detection limit in most of the cases. These phenomena have been the consequences of the unusual weather conditions (extremely low precipitation), which influenced not only the nutrient uptake by plant but also the microbial processing responsible for soil fluxes of trace gases.
