Abstract:
Grid based (GPS) surface (0-15 cm) soil samples by systematic survey were collected from 0 km of the sea coast (Bhavnagar, Amreli, Gir Somnath and Junagadh district) to 20 km towards inland. The distance between the sample locations was about 5 km from cultivated fields of different district of coastal region of South Saurashtra of Gujarat region. These soil samples were analyzed for determination of EC_e, pH_s, ESP, SAR and SSP to study the salinity status of soil. The value of soil EC_e is comparatively higher in the 0 to 5 km distance away from the sea coast. Whereas, the lower EC_e noted in the 15 to 20 km area. The soil EC_e and pH_s decreased with increased in distance from sea cost. The overall mean values of EC_e were 5.22, 3.94, 2.93 and 2.14 dS m^-1 and pH_s were 8.03, 7.85, 7.84 and 7.41 at 0-5, 5-10, 10-15 and 15-20 km from sea coast. The overall mean values of ESP were 17.44, 15.82, 15.53 and 14.91 at 0-5, 5-10, 10-15 and 15-20 km distance, SSP were 33.75, 35.20, 37.06 and 39.72 at 0-5, 5-10, 10-15 and 15-20 km distance and overall mean values of SAR content in soils of Southern Saurashtra coastal region were 2.28, 2.15, 2.09 and 1.96 at 0-5, 5-10, 10-15 and 15-20 km distance from seacoast, respectively. The result also revealed that the overall mean value of ESP and SAR were decreased with increased in distance from sea coast while SSP increased with increased in distance from sea coast.
