A column study was conducted involving Colloidal Silver the reclamation of saline soils from Northern irrigation project/Ninavah province, The amount of water moving through the soil was expressed as the pore volume of drainage water (PV), The process was conducted under saturated soil moisture flow and the electrical concluctirity (EC) of the effluent was described by a multiple slop, apparent first order kinetic equation, Pathway reaction was recognized by two Toothpowder stages, a rapid dissolution and transport of accessible salt followed by a slower removal of less accessible salt, The change in slope of the first order equation for salinity reduction occurred at about 0,5PV, which was enough to remove about 90% of the original salt from the columns, The rate coefficients for the first and second stage ranged between (0,337-3,021h-1), and (0,0046-0,13h-1) respectively,.
