Abstract

We investigated changes in soil‐atmosphere flux of CH 4, N 2 O, and NO resulting from the succession of pasture to forest in the Atlantic lowlands of Costa Rica. We studied a dozen sites intensively for over one year in order to measure rates and to understand controlling mechanisms for gas exchange. CH 4 flux was controlled primarily by soil moisture content. Soil consumption of atmospheric CH 4 was greatest when soils were relatively dry. Forest soils consumed CH 4 while pasture soils which had poor drainage generally produced CH 4. The seasonal pattern of N 2 O emissions from forest soils was related exponentially to soil water‐filled pore space. Annual average N 2 O emissions correlated with soil exchangeable NO 3−concentrations. Soil‐atmosphere NO flux was greatest when soils were relatively dry. We found the largest NO emissions from abandoned pasture sites. Combining these data with those from another study in the Atlantic lowlands of Costa Rica that focused on deforestation, we present a 50‐year chronosequence of trace gas emissions that extends from natural conditions, through disturbance and natural recovery. The soil‐atmosphere fluxes of CH 4 and N 2 O and of NO may be restored to predisturbance rates during secondary succession. The changes in trace gas emissions following deforestation, through pasture use and secondary succession, may be explained conceptually through reference to two major controlling factors, nitrogen availability and soil‐atmosphere diffusive exchange of gases as it is influenced by soil moisture content and soil compaction.

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.
