CH4 flux from different land uses in Argentina: natural grassland, pine afforestation and agricultural area.

This dataset contains values of soil methane flux (ng CH4 m-2 s-1) in four neighboring areas in a local ranch in the Argentinas Pampas (Tandil, Buenos Aires, Argentina; 37° 33´34.79 S; 59° 0.7´50.29´´ W). We studied an agricultural land (crop), a natural grassland area, and two pinus radiata afforestation with different tree densities. We use the static chamber technique to measure soil gas flux: 5 chambers per land use per measurement day. 12 measurement days were carried out between 2015 and 2019, covering all seasons. This data set also contains each chamber's average temperature (°C) and the atmospheric pressure (atm). This information was useful for determining the net soil CH4 flux of each surface and the effect of the human frontier between the natural land use and the agriculture or afforestation use, considering that the natural grassland is the baseline for this region.
