The Physical And Chemical Properties Of Soils For Environments Of Three Different Land/Iraq

Abstract

Abstract The current study performed for the period of March 2019 to February 2020 on three different land ecosystems in three Iraqi governorates which are Sulaymaniyah, Kirkuk, and Anbar. The samples of soil are collected from nine stations that close to the pollution sources. The stations are Bazian cement plant, North Oil concentration area, the main street in the modern desert which located between longitude and latitude of (45.062554-35.577087), (44.217077 - 34.406426), (42.269622 -34.8764) respectively. Some physical and chemical factors for soils are studied where their values ranged from the electrical conductivity of (0.13 - 2.86 EC dS/m), pH (7.21 - 7.97), organic matter of (0.31 - 10.89 g/kg), the total calcium carbonate of (164.16 - 390.10 g/kg), and the positive exchange capacitance of (3.03- 25.82 (centimol+Kg-1)). While values of the exchanged positive ions are ranged (Ca+2, Mg+2, Na+1 and Potassium K+2) ((0.10 (-8.43) and (1.0 –0.01), (1.93- 0.04), (0.04). (3.79 - cimmol/kg) respectively. Whereas the values of the dissolved positive ions (Ca+2, Mg+2, Na+1 and Potassium K+1) are recorded (0.03- (3.61, (1.82-0.01), (0.01-0.67), 0.55-0.01))/L) respectively. As for negative ions, their values are recorded (dissolved bicarbonate HCO3-and dissolved chlorine (Cl-1 (0.09 (1.65-, 0.76-0.05)) centimol/L).
