Abstract The formation of non-extractable residues of [14C]fenitrothion and their degradation in a black earth and a red yellow podzolic soil was studied. After a 65-day incubation, non-extractable radioactivity represented 73.7 and 59.35% of the applied radioactivity in the black earth and podzolic soil respectively, while evolved 14CO2 accounted for only 9.4 and 12.7%. The effects of various amendments and treatments on the degradation of the non-extractable residues to 14CO2 was studied. All of the amendments produced a priming effect and significantly increased the formation of 14CO2 in both soils. The addition of unlabelled fenitrothion and 3-methyl-4-nitrophenol to the black earth and 3-methyl-4-nitrophenol to the podzolic soil produced the greatest increases in 14CO2 evolution. The evidence presented suggests that a part of the unextractable residue is either fenitrothion or 3-methyl-4-nitrophenol.
