Effect of varying salt concentrations and Na/Ca ratios in the irrigation water on the soil salinity

Abstract: The current study was conducted on two soils extremely varied in their textures; i.e. sandy ( Meet Kennana area , Qalubia Governorate ) and clay soils ( El-Zankalon area, Sharkia Governorate) to investigate the effect of saline irrigation water on soil salinity levels, as expressed by the ECe values in the saturation extract of these soils. Three irrigation water treatments containing total salt concentrations of 1000, 2000 and 4000 ppm were used for irrigation. Moreover, each of these salt concentrations contained three different ratios of Na / Ca, i.e., 1: 1, 2: 1 and 4: 1.
The results revealed that increasing the total salt concentrations in irrigation water led to increase in soil salinity. Also, the Na / Ca ratios in the water did not cause in any significant difference in ECe . Salt accumulation in clay soil was much greater than in the sandy one. So, saline water could be used with a more efficiently under coarse textured soils. The period of irrigation was also greatly effected on the amounts of accumulated salts in both soils. The longer the period the higher will be the quantity of accumulated salts. The statistical analysis confirmed the above-mentioned results
