<p>This dataset presents C isotopic data from two sites (Apuí and Manacapuru) located in the state of Amazonas, Brazil. Soils were sampled at three time periods, under weak raining (March-2016), extreme dry (August-2016), and strong wet (March-2017) conditions. The dataset first presents general information about the site (on the tab "site"), followed by more detailed information (on the tab "profile") about both sampling locations. The coordinates, altitude, mean annual temperature, mean annual precipitation, soil order in USDA taxonomy and their respective land use categories and vegetation classifications are described. </p>
<p>On the 'layer' tab, information about the soil depth, percent sand, silt and clay, pH CaCl2 and H2O, Organic and Total Carbon, total nitrogen and carbon/nitrogen ratio are described. The bulk C-isotopic signature is also listed on this tab as the Bulk Layer Δ14C and its standard deviation, Bulk Layer Fraction Modern and its standard deviation. </p>
<p>The "Incubation" tab describes details of the soil incubations conducted at Apuí and Manacapuru. Information about the material and length of incubation, as well as the CO2 fluxes over the duration of incubation are reported. The respired C-isotopic signature during the incubation is also given on this tab as the incubation Δ14C and its standard deviation, incubation Fraction Modern and its standard deviation. </p>
