The study on some of the physico-chemical characteristics of salt affected and adjacent normal soils of Rohtak district indicate that, in general, clay content is more in normal soils as compared to adjacent salt affected ones and it increases with depth. Surface layers of all the salt affected and some of the normal soil profiles showed salt accumulation. Salinity hazard is more in Rohtak and Gohana tehsils and sodic in Sonepat and some parts of Gohana tehsil. Soils with high pH and high exchangeable Na along-with high salinity contain high amount of soluble boron as compared to those with comparatively low pH and low exchangeable Na alongwith high salinity. Presence or absence of Kankar layer is not a regular feature in either soils. Gypsum requirement is nil for salt affected soils of Rohtak, medium to high for Gohana and high for Sonepat tehsil.
