Abstract EN

Miscible displacement had been used in this research in salts leaching of the saline soil.then the soil samples were collected from alqizwinia reign at Al-Najaf city.

It was alluvium soil and salty for three location with three replicates .Soil samples were analyzed after soil prepared, the leaching process had been applied to study salts release by Kinetic concept to test which one among kinetic equation would be best one.

Also using the saline equilibrium equation to describe removal salts with through time.

The results showed as follow : 1- The binomial equation proceeding of salts release description than the others.

2-Decreasing of removal salts quantity via increased differential way with progressing of leaching time.

3-prediction of added or removal salts quantity via water irrigation and water table .

4- Possibility of Using these concepts into field work unless it will be fit with climate conditions disrespecting soil type and water quality.
