Abstract
Due to limited water resources utilization of unconventional water resources, is taken into consideration. The aim of this study was to evaluate changes in soil moisture under different irrigation water salinity under a line source in a layered heavy soil. For this purpose, irrigation times period of 2, 3 and 4 hours for volumes of 10, 15 and 20 liters and irrigation water salinity of 1.279, 2.5 and 5 dS/m were applied replicated three times.  In order to evaluate changes in soil moisture values a TDR device was used; and then the SURFER software using kriging method was used for zoning. The average soil moisture content was increased by increasing the water volume. The highest average volumetric moisture was in 5 dS/m treatment with 39.84% and the lowest one was in 1.279 dS/m treatment with 37.49%. According to SURFER outputs and the average volumetric moisture, in 5 dS/m salinity treatment the soil moisture in the surface layers was high, which is due to reduced permeability and hydraulic conductivity because of soil salinity increase. As the average soil moisture content is about at the field capacity of the silty clay soil, it can be said that drip irrigation system under limited water resources with a relevant quality has the necessary performance.
