ABSTRACT
The Direct Current method was used to investigate the soil salinity profile of marine shrimp aquaculture farm comparing with the rice field. Finite difference method was used with the iterative technique to minimize the potential difference of the calculated and the measured potential to give an optimal solution rapidly. The iterative technique of Quasi-Newton was used and found to be robust with respect to starting models for both the synthesis and real data. The results showed the conductivities for both the rice field and the marine shrimp aquaculture farm varied between 0.15 S/m to 0.22 S/m and 0.15 S/m to 0.33 S/m, respectively. Those number of conductivities indicated that the salt or mineral deposit in the ground from marine shrimp aquaculture farm did not have much of an impact on the plant since the conductivity, which implied salt and mineral deposit, of the ground used for growing rice should not more than 0.40 S/m. Therefore, both ranges of conductivity of the ground could be used for orchard and paddy.
