Evidence from experiments in which total nitrogen was estimated, as well as others in which the rate of fixation was measured, shows that the uptake of free nitrogen by inoculated red clover plants is inhibited by as little as 0.01% carbon monoxide. The fixation process is practically stopped by 0.05% carbon monoxide. In this range of pCO, no effect on assimilation of ammonium nitrate by uninoculated plants is observed, but at higher concentrations definite inhibition is detectable. The inhibition of nitrogen fixation appears to be reversible and non-competitive.
