Effect of Indiscriminate Removing Ground Water on Irrigation Water's Salinity in Arid Area, Central Iran

Irrigation water quality in arid areas is important because Iran is located in arid and semi- arid areas in the world, due this issue, strategies and guidelines of operation of saline soil and water should be encountered with a special priority. W rong managements, successive droughts and indiscriminate removing from groundwater tables in recent years, have caused the reduction in water table level and thus make the water quality poor in arid areas. So there is a necessity for extensive research works to solve this problem. This research was performed to study the effect of discriminate removing from groundwater on the quality of irrigation water in pistachio orchards in Anar area in Kerman. In this research, sampling from 30 selected shafts is accomplished. Also, from soil of 30 orchards that was irrigated with selected shaft's water sampling was done from 0-50 cm depth. For statistical analysis, required parameters including EC, SAR from 1991 until the years after 2008 were appointed that some parameters of soil and water analysis were evaluated based on standard methods, particularly FAO standards. The results of this research showed that the salinity and SAR parameters from the years 1991 until 2008 have had increasing range and with increasing water salinity, soil salinity has also been added.
