Summary In the present study an investigation about the transformation of added S35-labelled sulphate sulphur in an alluvial soil under aerobic and flooded soil conditions was made. After four months of incubation under laboratory conditions it was found that while in aerobic condition 68.1 per cent of the added sulphate is present, in case of flooded conditions it is only 12.7 per cent. The main transformation was into organic forms that is 28.1 and 37.8 per cent in aerobic and flooded soil conditions respectively. In aerobic condition 99 per cent of the added sulphate sulphur could be accounted for in different fractions determined viz sulphate, organic, humus, amino acid and evolved hydrogen sulphidesulphur. In flooded condition only 56 per cent was present in all these fractions, which indicates that remaining 44 per cent is in chemical forms between SO4 -2 and S-2.
