According to Fig.03, the Optimum Moisture Content of the BC soil has decreases gradually with the increasing of the salinity of water. For Normal soaked BC soil the omc value is 16.8 % and it is slowly obtained to 14.8 % at 0.05 M concentration of soil. It is observed that when the salt content added to the soil particles, then the particles are divided each other due to clay mineral salt reactions.
