Abstract
Soil CO 2 release from the mycorrhizal (M) and non-mycorrhizal (NM) FRPSDUWPHQWVZHUHPHDVXUHGXVLQJD/,&25/,,5*$V\VWHPÀWWHGZLWK soil respiration chamber. CO 2ÁX[HVZHUHGHWHUPLQHGLQWKHJURZWKFDELQHW used to raise the maize plants, and rates of CO2 release were determined at time zero and after 30 minutes intervals.

The magnitudes of these differences were largely the same in both M and NM systems at the second reading (0.05) indicating that equilibrium rates of respiration were being detected.
