Abstract |
: |
This study was carried out in Wadi Al-Ideraa, which is found in the middle of Hail city, extending parallel to Aja mountain series, and stretches from south to north east for 154 km to study soil classification, water quality and chemical pollution of some wild plants and some cultivated plant and Soils. Twenty-one soil profiles were chased to cover all the physiographic units for classify and evaluate soil of the study area. In addition to specify the water quality ( chemical and microbiological properties for the service and well water along Wadi Al-Ideraa to use in agriculture proposes based on the criteria of the Saudi Ministry of Water and Electricity (MWE, 2005) and (FAO, 1985). The satellites picture showed vast extension in the urban area between 1972 and 2007 causing increase of the vegetation index especially in the northern area because of the discharge of treated sewage water. Three physiographic units were found which were open desert, the valley and alluvial fans. The soil lands were classified according to the American System of Soil Classification, the results showed that Entisols, Inceptisoils and Aridisoils were the major soil order. the lands were evaluated which indicted to be mid good. The chemical properties of surface water were ranging between 1.38-5.27 (Dsm/cm) for EC, PH (7.2-8.3), BOD (2-35 mg/L), COD (9-160 mg/L). The concentration of most important captions were such as K+ (5.47-24.74 mg/L), Ca++ (2.67-4.14 mg/L), Mg++ (0.98-26.1 mg/L), Na+ (1.76-21.45 mg/L) and the highest value of SAR was 13.65, while the lowest value was 1.02. While the concentration of micronutrients and toxic metals such as Zn, Cd, Cr, and Pb of surface water were below Ministry of Water and Electricity standards' (MWE, 2005) and (FAO, 1985). Fecal coliform bacteria (FCB) were counted in range between 0-3520 cells/100ml. were higher in 6 locations of service water than Saudi and FAO standers. All of the following chemical concentrations of the micronutrients (Fe, Zn, Mn, Cu) and toxic metals metals (Cr, Cd, Ni, Pb) in soil and some cultivated and wild plants were all below the allowable standard values for soil (EU, 2002) and (WHO/FAO, 2007) for plants. |
