Conclude from the search (Estimate the quantity of water required to lavement saline soils according to crop production levels wheat and barley in district Al-Mdaina) , the district is located in the northern west of Basrah.

Its total area is(006933sq.m)its suffer from salty soil in the areas of dry marshes that reaches to (884713.

do) in basin area and (840373.d.

)with a total sum.

The research illustrates that the amount of water needed to lavement salty soil in uncultivated area Is about (190-8309 mm) in basin areas and between (8733- 8933 mm)in dry marshes.

In cultivated soil with wheat and barley crops , on the hand , the amount of water needed is equal to the amount needed to wash salinity soil (84470and 84471 mm) for the tow crops respectively with production level (035) that rises to (01774and41476 mm) in production level (8335) The average depth of the washing water of plants root area reach to(9370 cm) in river basin and (0979 cm) in dry marshes area.
