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 EC2.5 and between pHs and pH2.5. High correlation coefficient (r) and regression coefficient (b), high percentage of variance (R2) in case of EC2.5 and pH2.5 were observed and hence, prediction of ECe from EC2.5 and pHs from pH2.5 with greater precision was possible by using the regression equation for the soils of Porbandar district.

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 EC2.5 and between pHs and pH2.5. High correlation coefficient (r) and regression coefficient (b), high percentage of variance (R2) in case of EC2.5 and pH2.5 were observed and hence, prediction of ECe from EC2.5 and pHs from pH2.5 with greater precision was possible by using the regression equation for the soils of Porbandar district.
