Abstract
Two soil samples were selected, one of them from Rashidia and the other from Namrood location in Nenava. Electrolyte concentration used were (50, 150, 250 mmole-L -1) prepared using chloride salt of (Nacl, Cacl2.2H2O) with ratio 1: 9 to 9:1 and SAR value between (2.24- 40.0).
Wetting and drying experiment (irrigation frequency) was used. This experiment was carried out using a salt solution (50, 150, 250 mmole-L-1)and ten irrigation cycle for PH, Ec, soluble and exchangeable cations (NA, Ca, Mg). Wetting and drying (irrigation frequency) showed an increased value of electrical conductivity, soluble and exchangeable, Sodium, calcium and magnesium.
