  "abstract": "<p>This dataset presents C isotopic data from two sites (Apu&iacute; and Manacapuru)&nbsp;located in the state of Amazonas, Brazil. Soils were sampled at three time periods, under weak raining&nbsp;(March-2016), extreme dry (August-2016), and strong&nbsp;wet (March-2017)&nbsp;conditions.&nbsp;The dataset first presents&nbsp;general information about the site (on the tab &quot;site&quot;), followed by&nbsp;more detailed information (on the tab &quot;profile&quot;) about both sampling locations. The&nbsp;coordinates, altitude, mean annual temperature, mean annual precipitation, soil order in USDA taxonomy and their respective land use categories&nbsp;and vegetation classifications&nbsp;are described.&nbsp;</p>\n\n<p>On the &#39;layer&#39; tab,&nbsp;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 &Delta;14C and its standard deviation, Bulk Layer Fraction Modern and its standard deviation.&nbsp;</p>\n\n<p>The&nbsp;&quot;Incubation&quot; tab describes&nbsp;details of the&nbsp;soil incubations conducted&nbsp;at Apu&iacute; 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 &Delta;14C and its standard deviation, incubation Fraction Modern and its standard deviation.&nbsp;</p>",
