Soil development in Coastal Odisha is due to litteral deposits of estuarial intrusion of brackish tidal water from sea and lacustrine sediments of Chilika Lake. The present investigation aimed to assess the distribution of soil salinity and alkalinity in part of coastal Odisha with a view to effective management and adopting alternate cropping system. The study area was near to Bay of Bengal and Chilika lake, where frequently saltwater intrusion occurs to agricultural land. Study area is converted to different land management units (LMU); based on extent of fallow land and severity of salts. Soils were low in organic carbon (OC) content. Salt concentration (ECe) was varied from 6.94 to 16.86 dS m-1 and the highest was found in LMU 3. Soil cation exchange capacity (CEC) and base saturation (BS) were varied from 4.3 to 15.1 c mol (p+) kg-l and 67 to 95%, respectively. Exchangeable bases in all LMU were in the order of Ca2+> Mg2+> Na+> K+. Results of soil fertility in different depths (0-15 and 15-30 cm) revealed that the available N, P and Zn were deficient and K, Fe, Mn and Cu were sufficient. Assessed soil and water salinity/alkalinity could able to suggest appropriate crop and land managements to each LMU. Not Available |
