Soil pCO2, soil respiration, and root activity in CO2-fumigated and nitrogen-fertilized ponderosa pi little to total soil CO. efflux in the field. Measurements of soil pCO. and calculated CO. efflux provided inexpensive, non-invasive, and relatively sensitive indices of belowground response to CO. and N treatments.

Management — Preliminary Argument Range in northeastern Colorado, USA and transferred to controlled environment chambers. Cores were exposed to a variety of water, temperature and CO. regimes for a total of four annual growth cycles. Root subsamples were harvested after the completion of the second and fourth growth cycles at a tim
