An experiment in which the effect of increasing periods of chloroform fumigation on nitrification in soil was determined indicated that the active nitrifying bacteria were located at sites in the soil which were readily accessible to diffusing gas. This suggestion was supported by the distribution of potential nitrifying activity in relation to soil pore size, which indicated that nitrifying bacteria were concentrated in soil pores in the size range 136–214 μm.
