Abstract: The present study was carried out with an objective to evaluate fertility status of surface soil from salt affected area of Dholka taluka. Soil samples were analyzed for their physical and chemical properties. It was observed that average bulk density and particle density of soil were found 1.28 and 2.44 Mg m-3, respectively. The lowest soil porosity was observed in Koth village (40.13%), while, highest value (56.77%) was recorded in Arnej with an average of 47.48%. In case of maximum water holding capacity (MWHC), it found 38.98%. The soils of Javaraj, Arnej, Anandpura, Koth, Ambareli and Dholi were comes under clay textural class. Vataman and Simej soils comes under clay loam and clay textural class whereas, loam textural class was observed in case of Khatripur and Bhetawada soils. The soil pH was found moderately alkaline and soil salinity (EC) was found 1.31 dS m-1 (tending to become saline). The soil organic carbon (SOC) was found 0.43% (medium). In case of different major nutrients, available nitrogen, P2O5, K2O and S were 185 kg ha-1 (low), 23.08 kg ha-1 (low), 246 kg ha-1 (medium) and 7.7 ppm (medium), respectively. The exchangeable cations (Ca++, Mg++, K+ and Na+) in the entire area were 15.5, 11.9, 0.53 and 8.1 me/100 g soil, respectively. Moreover, the DTPA extractable micronutrients (Fe, Mn, Zn and Cu) were 11.1 ppm (medium), 13.2 ppm (medium), 1.19 ppm (high) and 1.69 ppm (high), respectively. Simple correlations (r) of available S with Fe and Cu, available N with available P2O5, OC and Cu and available P2O5 with OC were found significantly positive at 0.05 level. Significantly positive correlations at 0.01 level were observed in case of available N with available K2O, available S with OC, available N with available S and available P2O5 with Zn.
