520 _aFactors affecting the charge characteristics and buffering capacity were studies on synthetic components similar to those found in natural soils and also on soil samples represente alluvial ( Torriorthents ) and calcareous ( calciorthids ) and some of their clay separates . The statistical analysis showed significant correlation between both ( O`t) and ( O`p ) and variable charge ( O`v) and clay amorphous material as well as free Fe₂O₃, Al₂O₃ and SiO₂ oxides in the alluvial soils while it was correlated to clay, total and active carbonate in calcareous soils
