  Considering of saline soils in middle part of Khuzestan province, Iran and also the leached soils having capacity to be saline, the irrigation agenda or the percent of irrigation water emission from the roots region must be adjusted and controlled so that a desirable balance of soil salinity in roots growth region is created to prevent salinization of soil after soil optimization. Therefore, current research is about the water and salt balance in roots growth region of sugarcane cultivated soils. Accordingly, the values of ΔZ (the variations of salinity supply), Z1, Z2 (the first and second concentration of salt level in the region of roots growth) and ECe (electrical conductivity level of saturated soil) in different months of cultivation year were calculated. The results indicated that calculated ECe had the intervals between 2.26 dS/m and 2.59 dS/m that by 10% crop decrement, it is less than determined allowable maximum,that is, ECe = 3/4 dS/m. On the other hand, the level of depth percolations resulting from irrigation showed the control sufficiency of salt accumulation in the depth of roots growth and the desirable agronomic conditions to plant growth are provided.
