Thirty soil samples were collected from different land types at the study area and analyzed at Soil Resource Development Institute (SRDI) to determine soil nutrient status. The soil parameters under investigation included pH, organic matter (OM), total nitrogen (N), available phosphorus (P), available zinc (Zn), available iron (Fe), available manganese (Mn), available boron (B), exchangeable potassium (K), exchangeable calcium (Ca) and exchangeable magnesium (Mg). Results indicated that many of the soil nutrient levels decreased such as pH (5.63 to 6.40), P (3.50 to 23.20 µg g-1), Zn (3.27 to 3.60 µg g-1), Mn (21.12 to 57.90 µg g-1), B (0.17 to 0.60 µg g-1), K (0.18 to 0.30 meq 100g-1) and Ca (5.75 to 9.10 meq 100g-1). On the contrary, the average content of OM (2.30 to 1.40%), Fe (248.22 to 161.10 µg g-1) and Mg (2.07 to 1.80 meq 100g-1) were increased.
