Soil bound /sup 14/C-labeled residues were released by four different physiological groups of microorganisms from an organic soil treated with /sup 14/C-ring-labeled prometryn (2-(methylthio)-4,6-bis(isopropylamino)-s-triazine). The extent to which the different microbial populations released bound /sup 14/C residues (25-30% of the total bound /sup 14/C) from the gamma-irradiated soil after 28 days incubation did not differ considerably. Analysis of the extractable material from the incubated soil showed the presence of small amounts of the parent compound, and its hydroxy and mono-N-dealkylated analogues. Low level of /sup 14/CO2 (1.5-3.0% of the total bound /sup 14/C) was evolved from the microbial systems indicating ring cleavage of the released material as being a very minor reaction.
