- ABSTRACT The study of land degradataion in Nakasongola, Uganda was conducted to asses the effects of land use conversion and slope position on soil chemical and physical properties consisting of soil organic matter, total nitrogen and available phosphorus, exchangeable bases, cationic exchange capacity, bulk density, porosity and soil texture. Soil samples were collected at different slope positions in closed areas and free grazing lands. Five and ten years closed areas had significantly (p < 0.05) higher levels for organic matter, nitrogen and phosphorus compared to free grazing lands. The highest levels in organic matter, nitrogen and phosphorus were observed at foot slope position in closed areas. An increasing trend from upper slope to foot slope position for soil nutrients was also found in closed areas, but not in free grazing lands.
