Irrigation Water Impact on Soil Properties in Arid Oued-Souf Region, Southeast Algeria

The perimeters of the Oued-Souf region are irrigated by salty water coming from phreatic and thus progressive salinization soil occurs. This study aims at a qualitative analysis evolution salinity in soils pivot irrigation for several years. For this, three plots were pivots each agricultural region. choice these 3 is justified number years their cultivation: plot 1 has been cultivated 2 (2016–2017), 5 (2016–2020) studied compared to controlled not irrigated. done sprinkling with mineralized water. results obtained showed that characterized high low sodium adsorption ration (SAR). Sodium chloride contents excessive sprinkler mode. between was very significant control (non-irrigated). goes 0.38 dS/m site classified as 1.54 soil. geochemical facies regions after sulfate-calcium. A correlation observed calcium sulfate electrical conductivity (EC), so our dominated sulfate. These confirmed statistical data (PCA), which revealed heavily influenced Mg2+, Ca2+, SO42- topsoil.
