| Description
| - Relationships between CH4, CO2, and N2O emissions were studied in soil that had been freshly amended with large deposits of cattle wastes. Dynamics of CH4, CO2, and N2O emissions were investigated with flux chambers from early April to late June 2011, during the 3 months following cattle overwintering at the site. This 81-day field study was supplemented with soil analyses of available C and N content and measurement of denitrification activity. In a more detailed field investigation, the daily time course of emissions was determined. The field research was complemented with a laboratory experiment that focused on the short-term time course of N2O and CH4 production in artificially created anoxic soil microsites. The following hypotheses were tested: (i) a large input of C (and N and other nutrients) in cattle manure creates conditions suitable for methanogenesis, and therefore overwintering areas can produce large amounts of CH4; (ii) N2O is produced and emitted until the level of mineral N decreases, while the level of CH4 production is low; and (iii) production of CH4 is greater when N immobilization decreases the level of NO3- in soil. N2O emissions were relatively large during the first 3 weeks, then peaked (at ca. 4000 µg N2O-N m-2 h-1) and soon decreased to almost zero; the changes were related to the mineral and soluble organic N content in soil. CH4 fluxes were large, though variable, in the first 2 months (600-3000 µg CH4-C m-2 h-1) and were independent of C and N availability. Although time courses differed for CH4 and N2O, a negative relationship between N2O and CH4 emissions was not detected.
