Abstract

Seventy three surface (0-15 cm) soil samples from the three talukas viz., kutiyana, Ranavav and Porbandar of Porbandar district were collected from the cultivated fields and were analyzed for different chemical poperties. The results revealed that Na⁺ and Cl^- were dominant among the water soluble ions, whereas, Ca⁺⁺ and Mg⁺⁺ were dominant among the exchangeable cations. Nearly half (48.0%) of the cultivated coastal soils of Porbandar district were found normal in nature, followed by sodic (20.5%), saline (16.4%) and saline-sodic (15.1%).

Abstract

Seventy three surface (0-15 cm) soil samples were collected from the cultivated soils of Porbandar district, and were analyzed for EC and pH from saturation extract and 1:2.5 soil water ratios. The results revealed highly significant correlations between ECe and EC_2.5 and between pHs and pH_2.5. High correlation coefficient (r) and regression coefficient (b), high percentage of variance (R²) in case of EC_2.5 and pH_2.5 were observed and hence, prediction of ECe from EC_2.5 and pHs from pH_2.5 with greater precision was possible by using the regression equation for the soils of Porbandar district.

Keywords
