Over the course of an eight-year open-top-chamber CO2-enrichment (to twice ambient concentrations) study of a pristine (annually burned) tallgrass prairie north of Manhattan, Kansas, USA, which was composed of a mixture of C3 and C4 species, Williams et al. measured changes in the active, slow and passive pools of carbon (C) and nitrogen (N), with the goal of determining how they were impacted by the doubled atmospheric CO2 concentration of their reasonably long-term experiment.
