Nowadays, due to population increasing and agricultural land loosing, optimum usage is essential, so land
susceptibility must be evaluated prior to land suitability. The models generally are the simplified facts of reality which can
be applied for determining yield production and site speciation of suitable strata. Geostatistical observations were integrated
with GIS to create continuous soil properties maps. Hereby, number of 56 and 15 samples were collected for modeling and
geostatistical analysis, as well as testing the accuracy of maps, respectively. Spherical and exponential models were
identified as the best fitted models due to higher R2 and lower RMSE. The results revealed that pH, Pabs, clay and CCE in
the vast area while EC and CEC in a part of studied area were recognized as limiting factors for Damask rose cultivation.
Proper management decisions will be beneficial for improvement of some soil temporary limitations. Correcting of pH in an
area of 22 ha (i.e.) may improve the land. Leaching the soil (3.459 ha) with high quality of water is also required to move
the salinity with low cost to achieve the best suitable land for purpose. On the contrary of other parameters, clay has limiting
impact on 15.83 ha which it is not possible to be corrected.
