Abstract: In this study, the long-term impacts of poultry manure (PM) on vertical distribution of soil macronutrients (N, P, K, Ca and Mg) have been determined. In addition, change in other soil fertility indicators such as organic matter (OM) and cation exchange capacity (CEC) levels were assessed. Soil samples from four depths (0-15, 15-30, 30-60, and 60-120 cm) from the sites were analyzed. Generally, the mean total soil nitrogen increased with depth in the cultivated poultry manure amended soils up to 60cm depth and decreased sharply at depth range 60-120 cm in both wet and dry seasons. At both the cultivated and uncultivated sites at Deduako, available P levels were highest at the top 15 cm depth of the soil and decreased rapidly with increasing depths for both seasons in both the cultivated and uncultivated sites. The exchangeable K content at Deduako during the wet and dry season was significantly higher at all sampling depths than the corresponding depths of uncultivated land. Generally, the exchangeable Ca levels were significantly higher in cultivated soils at the experimental sites than those of the uncultivated land. There were significantly higher exchangeable Ca levels in wet season than that of dry season at both sites. Significantly higher (p < 0.05) Mg levels recorded in wet season. The OM contents at all sampling depths of cultivated site were also higher than that of the uncultivated sites. At the Deduako vegetable site, during the wet season, the CEC in cultivated soils at the various sampling depth were significantly higher (p < 0.05) than those of uncultivated soil. Increases in all selected soil properties were, generally, higher in the wet season than the dry season.
