Evaluating the Effect of Water Quality and Irrigation Methods on the Distribution of Soil Salinity in the Semi-Arid Region of Corbal Plain

The current study was carried out with the aim of evaluating the effects of pressurized and furrow irrigation methods on the distribution of salinity and moisture in the soil profile. The experimental study design was a split plot layout with three irrigation method including furrow, surface drip (SD) and subsurface drip irrigation (SSD) using two water qualities, municipal effluent (0.509 dS/m salinity) and fresh water (1.52 dS/m salinity) which was carried out in a corn field located in Corbal plain, Iran. Soil sampling was conducted in two sessions, prior to irrigation and after harvesting, at three depths of 0-20, 20-40, 40-60 cm and 15 points around areas where water seeped. Variance analysis of salinity showed a significant difference (p
