Fluxes of Nitrous Oxide from soils under afforestations in Tandil and Balcarce (Buenos Aires, Argentina): A dataset

Abstract

The data set presents the nitrouse oxide (N2O) fluxes and related soil and climatic parameters from a mix-species, a pinus and an eucaliptus afforestation. These are located in Tandil and Balcarce (Buenos Aires, Argentina). Sampling period varies between 1 and 2 years, and sampling dates differing site to site. To measure N2O fluxes, the static chamber technique was used and sample collection each date occurred between 10 AM and noon for 1 hour. Gas samples were measured with a gas chromatograph (GC, Agilent 7890A) equipped with an ECD. The fluxes were calculated using the slope of a linear regression between N2O concentration inside the chamber vs time. During the same sampling dates, soil was sampled to obtain soil water content, bulk density, filled-water pore space, ammonium, nitrate, organic matter and pH. Also, soil temperature was measured in the site and daily temperature was obtained from the Argentinian national meteorological service (SMN) and the National Agricultural Technology Institute (INTA).
