Abstract EN

Knowledge of Soil Characterstics (Texture, Soil PH, Soil Salinity, Calcium Carbonate Percentage, and Soil Moisture Content) in Al-Hassa Oasis is essential for effective dune stabilization by growing plant؟.

The sand content of the soil samples from dunes in Àl-Hassa Oasis is greater than 93%.

PH ranges between 6.8 To ?.ء and soil salinity between ,60 and 4,60 mmhos/cm.

The average calcium carbonate and soil moisture content for the dunes soil sample in the study area is 2.24 and 2,04% respectively.

The result of the multiple regression equation indicates that there is about 52% of variance in soil moisture modeled by the two independent variables.

The result of the Analysis of variance equation indicates that the soil sample depth does not have significant effect on soil moisture (08,ت=مأ), but there is a significance for the parts of sand dunes on soil moisture (R^ = ,54).
