“…The permeability index (PI) classifies the researched waters as moderately good for irrigation. The SAR, often used in assessment of water for irrigation purposes [4,8,9] amounts from 5 to 16 for waters of Mhamid Oasis. SAR informs about the possible level of ion exchange between sodium and calcium and magnesium.…”

“…It is assumed that for water for irrigation purposes the EC should range from 600 to 1700 µS·cm -1 [5]. However, values are higher in many areas in the hot, arid zone, what makes their usage for irrigation purposes significantly limited [6][7][8][9]. Nonetheless, as there are no other sources of water, they are used for irrigation, what leads to increased soil salinity.…”

“…Nonetheless, as there are no other sources of water, they are used for irrigation, what leads to increased soil salinity. The problem occurs in more than hundred countries, encompassing 0.95 Gha, what constitutes approximately 7.3% of the land surfaces [8,10]. The total surface degraded because of irrigation with salinated water is estimated at 80% in Turkmenistan [11] and at approximately 30% in Egypt [12,13], Iran [4] and Pakistan [14].…”

Abstract:In arid zones, the availability of fresh water is usually very limited because of high salinity, which greatly limits their use for irrigation purposes. High mineralization of water used for irrigation leads to increased soil salinity. The aim of the study was to examine the potential use of alluvial groundwater for irrigation in arid zones. The works were conducted in the Middle Draa Valley in southern Morocco (the Mhamid Oasis) in October 2015. Water samples of alluvial groundwater were collected for laboratory analysis from 42 wells located in the oasis. In order to determine the possibility to use the water for irrigation purposes, the Sodium Adsorption Ratio (SAR), sodium percentage (%Na), permeability index (PI), Kelly's ratio (KR), magnesium hazards (MH) and electrical conductivity (EC) were assessed. EC values, exceeding 3000 µS·cm -1 in all the samples, classify the water as unsuitable for irrigation. MH and the KR indexes show that 30% of water samples represent levels making them unsuitable for irrigation. SAR confirms the very high degree of susceptibility of the analyzed waters to salinity hazard. The PI index of these waters is moderate, however in terms of sodium content they can be deemed suitable for irrigation purposes. It has been found that even within a small area of the oasis, a very large differentiation in the alluvial groundwater suitability for irrigation purposes occurs.

“…Increasing total salt contents in water can pose serious problems in terms of the quality of irrigation water (Simsek and Gunduz, 2007). The IWQI provides a clear definition of how optimal water conditions should be chosen by a single value, thereby minimizing complex data-based water quality evaluations (Ghazaryan and Chen, 2016).…”

In this study, the physical and chemical characteristics of wet and dry season groundwater quality parameters of 35 wells within the provincial boundaries of Sivas were used for calculations such as sodium adsorption ratio (SAR), Kelly's ratio (KR), sodium percentage (Na%), permeability index (PI), residual sodium carbonate (RSC) and magnesium hazard (MH), which are used in irrigation water quality ratings. Also, the irrigation water quality index (IWQI) was calculated for all groundwater sources within the study area. Groundwater quality parameters and the spatial distribution of the parameters calculated throughout the study were mapped using GIS, and irrigation water quality evaluation was performed in accordance with USA Salinity Laboratory diagram and irrigation water quality standards. The correlations between the irrigation water quality parameters were determined using Pearson correlation analysis. IWQI values showed that the majority of groundwater samples (45.7%) are in the ‘weak' (MR: medium rating) category for the dry season, whereas 42.9% of groundwater samples fall within the ‘very weak' (HR: high restriction) category for the wet season. © 2019 John Wiley & Sons, Ltd.

Significant anthropogenic and biophysical changes have caused fluctuations in the soil salinization area of the Keriya Oasis in China. The Driver-Pressure-State-Impact-Response (DPSIR) sustainability framework and Bayesian networks (BNs) were used to integrate information from anthropogenic and natural systems to model the trend of secondary soil salinization. The developed model predicted that light salinization (vegetation coverage of around 15-20%, soil salt 5-10 g/kg) of the ecotone will increase in the near term but decelerate slightly in the future, and that farmland salinization will decrease in the near term. This trend is expected to accelerate in the future. Both trends are attributed to decreased water logging, increased groundwater exploitation, and decreased ratio of evaporation/precipitation. In contrast, severe salinization (vegetation coverage of around 2%, soil salt ≥20 g/kg) of the ecotone will increase in the near term. This trend will accelerate in the future because decreased river flow will reduce the flushing of severely salinized soil crust. Anthropogenic factors have negative impacts and natural causes have positive impacts on light salinization of ecotones. In situations involving severe farmland salinization, anthropogenic factors have persistent negative impacts.
