On a per-unit-biomass basis, Smart et al. (1998) noted there were no differences in the total amounts of nitrogen within CO2-enriched and ambiently-grown wheat seedlings after three weeks of exposure to atmospheric CO2 concentrations of 360 and 1,000 ppm. Nevertheless, the CO2-enriched seedlings exhibited greater rates of soil nitrate extraction than did the ambient-grown plants.
