Methane emission from tropical savanna Trachypogon sp. grasses
Description (Dublin Core)
Methane flux measurements from the soil-grass system were made during the wet season in unperturbed plots and plots where standing dry and green <i>Trachypogon sp.</i> grasses were clipped to just above the soil surface. Results support the surprising discovery that vegetation emits methane. The results of this work allows to infer that the savanna dry/green mixture of grasses produce methane at a rate of ~10 ng m<sup>−2</sup> s<sup>−1</sup>, which is in agreement with early published soil-grass system fluxes. An extrapolation of this flux to the global savanna produces an annual emission much lower than the CH<sub>4</sub> production recently suggested in the literature. On the other hand, during the wet season savanna soil consume CH<sub>4</sub> at a rate of ~4.7 ng m<sup>−2</sup> s<sup>−1</sup>. Therefore, the tropical savanna soil-grass system would make a modest contribution to the global budget of methane.
