Abstract
The amount of gibbsite in the clay fraction of T terrace soils appears to increase with the increase of sand content and with the improvement of drainage conditions. Kaolinite is the main mineral in the clay fraction of soils. The imperfectly and poorly drained ones may also contain some mica chloride mixed layers and feldspar. Anatase accumulates in the silt fraction of the well drained soils. The dominance of 1:1 clay minerals and/or sesquioxides is reflected in their physico-chemical properties. Apparent cation exchange capacity (CEC) decreases with a decrease in silt/clay ration. Water dispersible clay (WDC)/Clay appears to decrease with an increase in Al and/or organic matter. The ratio also decreases as the pH approaches pH
