Abstract:
Some physical and chemical properties of some upland and wetland soils of Rivers State Nigera were investigated to ascertain the effect of these soil forms on soil properties. 6 profile pits were sunk in Ogba/Egbema, Port Harcourt and Etche Local Government Areas of the State; each representing either an upland or a wetland soil. Samples collected from the various horizons were analyzed for selected soil properties. Results showed that the wetland soils had shallow water tables ranging from 46 to 60cm depth. The percentage of sand, organic matter, available P, total nitrogen, iron content and cation exchange capacity were higher in most locations and horizons than the at the upland soils. pH was generally acid across all locations. The mean values at the Ap horizons ranged between 5.06 to 5.87. Iron content for wetland soils, at the Ap horizon ranged between 333 to 2000mg/kg with the highest for Port Harcourt and the least for Etche.
