Field experiment was conducted for the cultivation of crop tomato in the Al-Bargasia province of Basrah.

The soilof the site was a sandy loam .Two sites were selected the salinity of the first site well was 12 dS /m The salinity of the second 6.5 dS /m, Tomato crops (AL-Oula class ) has been cultivated on 19/8 / 2011 in both locations.

the experiment Conducted by using magnetized water with levels of phosphate fertilizer (P120, P60, P0) for both locations.

The results were appeared show that the salinity of irrigation water at the first site led to decrease the concentration of dissolved phosphorus in the soil that was (1.3 , 6.5 and 14.7) mg / l for the levels of phosphate fertilizer (P120, P60, P0), respectively, compared with the concentration of dissolved phosphorus (3.3 , 7.9 and 18.2 mg / L) in thesecondlocation.

As in the Treatment of magnetized water, Concentration of dissolved phosphorus (2.3 , 12.5 and 17.5) mg / l levels of fertilizer phosphate (P120, P60, P0), respectively, compared with concentration of dissolved phosphorus (1.5, 12.3 and 16.8) mg / L in the comparison treatment (without magnetization) at the first site.While In the second site was the values of phosphorus dissolved in the treatment of magnetized water was (3.2 , 15.5 and 19.8) mg / l for the levels of phosphate fertilizer (P120, P60, P0), respectively, compared to concentration of dissolved phosphorus (1.5 , 13.5 and 18.4) mg / liter in a comparison sample.
