Abstract

In this study, the physico-chemical properties of soils of Nasarawa State University, Keffi were determined using physico-chemical methods of analysis. Parameters determined are soluble salts (12.3±0.02- 14.3±0.00/o); soil air (I. 30%); organic matter (1.5±0.00-3.6±0.01%); available water capacity (8.0-18.3%) and pH (6.42-7.52/o). Other parameters included saturation percentage (30.2±0.05-35.2±0.01%); moisture percentage (0.31±0.02-0.49^0.01 /o), percentage loss on ignition (0.98±0.01-2.39±0.03%) and texture (sand, 51.0^0.25-60.6±0.35; silt, 16.0^0. 26.7±0.04 and clay, 14.1±0.04-22.0±0.00%). Phosphorus, nitrogen and exchangeable cations were also determined. Results indicate low values for all parameters determined compared with earlier workers and FA 0 specification.
