Twenty one soil profiles representing three bio-sequences viz., cultivated lands, forest lands and
grasslands were collected to characterize the soils of Kathua district of Jammu region, J&K state, North
India. The cultivated soils profiles exhibited comparatively more depth than those under forest and
grasslands. Most of the studied soil profiles had angular to sub-angular blocky structure. The soil pH
and EC values, irrespective of depth varies, from 4.4 to 7.1 and 0.10 to 0.97 dS m–1 with average weighted
mean of 4.49 to 6.65 and 0.17 to 0.80 dS m-1, respectively. Organic carbon (OC) and total N content were
more in soils of grasslands followed by those of cultivated and forest lands with comparatively low
values of C:N ratio in cultivated soils. Cation exchange capacity (CEC) of soil varied widely in horizons
ranging from 5 to 19 Cmol (p + ) kg–1 with average weighted mean of 5.3 to 16.18 Cmol (p + ) kg–1. The
greater values of CEC were observed in case of grassland soils. CEC showed positive correlation both
with organic carbon (r = 0.55 * * ) and clay content (r = 0.40 * * ). The soils belong to order Entisol, Inceptisol
and Alfisol. As per land capability classification, cultivated lands were grouped with subclass IIs, IIIw,
IVe and IVes, while forest soils were mainly in IIIes, VIe, VIes, and grassland soils in IIIe, VIIes, IIIs
and Vs
