Résumé
This reseach processing plant and the effects of irrigation by treated wastewater (TWW) on the morphological, formation, mineralogical and geochemical properties of sandy calcareous soils in the South Misura region. In this context, 12 AAS samples were collected once a month for a year. Comprehensive Pollution Index (CPI) and Organic Pollution Index (OPI) classified these waters as mild and moderately dirty. Among the trace elements analyzed (Fe> Mn> Zn> Co> Cu> Cd> Pb> Cr) Cd concentration was higher than the desired limit value for irrigation water. Piper’s diagram shows that most of the AAS samples fall into the calcium bicarbonate region. The integrated salinity and alkalinity effect that occurs in the US salinity diagram in all AAS samples shows that AAS samples decrease in high salinity and low sodium change hazard (C3-S1), pH, EC, Sodium Adsorption Rate (SAR), Total Dissolved Solids (TDS), Solublarch explores the quality of treated wastewater produced for irrigation by the Misurate Sodium Percentage (SSP) is within the permitted limits for Magnesium Hazard (MH) and Residual Sodium Carbonate (RSC). Soil samples were obtained from three horizons (A, B and C) of six AEDs (29 years) watered with AAS and six other peds (dry control) from other non-irrigated areas. The results are significantly higher salinity (EC), sodium adsorption rate (SAR), changeable sodium percentage (ESP), cation exchange capacity (CEC), availeble phosphorus (AP) and total nitrogen (TN), compared to control peds of AAS-watered pedon. ), it has been found to be relatively higher in terms of organic matter (OM). However, all relevant values (EC <4 000 µs/cm
