A comparative study of two foot-slope soils on similar parent materials in the Nsukka area of eastern Nigeria was carried out to determine their characteristics, ascertain their differences, and find out reasons for the differences. The differences were related to the thickness of the Ap horizons, sand and clay contents, organic matter contents, exchangeable bases, cation exchange capacity, exchangeable acidity, and gibbsite contents in the less than 2-μm clay fractions and the available phosphorus. The major reasons for the differences were related to the differential rates in certain soil formation/degradation processes resulting from differences in the cultural practices in the two sites and the longer period of land cultivation on the University of Nigeria, Nsukka (UNN), farm than on the Community Secondary School (CSS) farm. The parent material of the soil tended to influence the soil properties on equal basis. The soils were classified, respectively, as fine-clayey, kaolin-itic, isohyperthermic Rhodic Kandiustalf (Haplic Lixisol) and fine-loamy, silicious, isohyperthermic Rhodic Kandinstult (Haplic Acrisol).
