Abstract

At bulk density of 0.97 g/cm3 and pH (top soil) of around 5 reflects that the soil had improved after undergoing an ameliorating programme and more than a decade of cultivation. But at depth(subsoil pH) was still low where Al was presented in large quantities. A high water table leads to the accumulation of bases especially Ca and Na in the lower horizons. Low pH and high cation exchange capacity was due high amounts of organic matter and mica-vermiculite-smectite mineralogy
