Fluxes of nitrous oxide and methane on an abandoned peat extraction site: Effect of reed canary grass cultivation
Abstract
Drained organic soils are among the most risky soil types as far as their greenhouse gas emissions are considered. Reed canary grass (RCG) is a potential bioenergy crop in the boreal region, but the atmospheric impact of its cultivation is unknown. The fluxes of N(2)O and CH(4) were measured from an abandoned peat extraction site (an organic soil) cultivated with RCG using static chamber and snow gradient techniques. The fluxes were measured also at an adjacent site which is under active peat extraction and it is devoid of any vegetation (BP site). The 4-year average annual N(2)O emissions were low being 0.1 and 0.01 g N(2)O m(-2)a(-1) at the RCG and BP sites, respectively. The corresponding mean annual CH(4) emissions from the RCG and BP sites were also low (0.4 g and 0.9 g CH(4) m(-2)a(-1)). These results highlight for the first time that there are organic soils where cultivation of perennial bioenergy crops is possible with low N(2)O and CH(4) emissions.

Given proper site selection, dedicated energy crops can be cultivated even on organic soils with low N2O emissions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
