These three files contain data on carbon and carbon isotopes in air, plants and soils from the 1998-1999 Free-Air CO2 Enrichment (FACE) experiments conducted at the Maricopa Agricultural Center, Arizona. The study traced the movement of carbon from carbon dioxide in the atmosphere into plants, and then into soils. These are the data used in a paper published in LAND (2022), titled "Soil organic carbon isotope tracing in sorghum under ambient CO2 and Free-Air CO2 Enrichment (FACE)".
