An attempt had been made in the present investigation to study the soil properties of Northern Saurashtra coastal region (Jamnagar, Devbhumi Dwarka and Porbandar district) of Gujarat by collecting 141 grid based surface (0-15 cm) soil samples from farmer’s cultivated field, through the use of GPS at distance demarcation of 0-5, 5-10, 10-15 and 15-20 km from sea coast, during May, 2019 and were analyzed for different chemical properties.

The soils were low with respect to available N (204.70 kg ha^-1), but medium in available P2O5 (28.95 kg ha^-1) and S (20.00 mg kg^-1), whereas high in K2O (401.82 kg ha^-1) status. The overall available (DTPA extractable) Fe, Mn, Cu and Zn varied between 2.92 to 8.92, 1.32 to 18.80, 0.13 to 7.31 and 0.06 to 3.58 with their corresponding mean values of 5.44, 7.45, 1.01 and 0.46 mg kg^-1, respectively. The available B was found high and it was ranged from 0.78 to 6.61 with the mean value of 3.49 mg kg^-1.

On the basis of analyzed data, it can be concluded that all the fertility parameters viz., available N, P₂O₅, K₂O, S, Fe, Mn, Cu and Zn content were increased with increasing the sampling distance (0-5, 5-10, 10-15, 15-20 km) from coastal line except B.
