Spatial variation in the emission rates of nitrous oxide (N 2 O) and methane (CH 4) in soils can be significant due to the diverse biological, chemical, and physical conditions that influence the production and consumption of these gases. Drained organic soils are known to be hotspots for N 2 O emissions, and in wet conditions they can also emit CH 4. We measured N 2 O and CH 4 fluxes during the winter and growing season at 28 locations across a 7-ha area of drained organic agricultural soil in Eastern Finland. Our findings revealed expected high spatial and temporal variations in emission rates. The measured N 2 O emissions varied between −0.003 and 30.4 mg N 2 O m−2 h−1, averaging at 0.94 ± 3.00 mg N 2 O m−2 h−1 and CH 4 emissions varied between −0.27 and 2.90 mg CH 4 m−2 h−1, averaging at 0.10 ± 0.33 mg CH 4 m−2 h−1. Phosphorus concentration was identified as a limiting factor and a critical determinant of spatial variations in N 2 O emissions, whereas CH 4 emissions exhibited a decreasing trend with increasing sulphur and nitrate concentrations. Our study shows that N 2 O and CH 4 fluxes are linked to other elemental cycles, making it critical to identify key nutrient-related processes that govern the spatial and temporal variability in emissions of these gases.
