Fortysix soil samples each from surface (0-22.5 cm) and subsurface (22.5-45.0) were
collected from 4 Great soil groups of Jammu districts, viz, Haplaquent, Ustifluvent, Ustorthent
and Eutrochrepts. The samples were analysed for PH, organic carbon, CaC03, sand silt and
clay (%) by standard methods (Jackson 1973). Total S was estimated by the method of
Tabatabai (1952) and orgainc S by digesting with HP2 (Evans and Rost 1945) and
subsequently extracted with NaCI solution (Williams and Steinberg 1959). The sulphate S …
