Abstract
The electrical conductivity (EC) Resistively (calculated) and salinity of some selected soil samples collected from three landforms, namely Beach Ridge Sand (BRS), coastal plain sand (CPS), sandstone/shale Hill ridges (SHR) from Akwa Ibom State of the Federal Republic of Nigeria were measured the obtained data were subjected to spearman rank order statistics and result shows that there were positive correlation of 0.20 between soil EC and salinity. The electrical conductivity of the area under study falls within the range of 0.031 ds/m for SHR 3A t0 0.200ds/m for SHR 2A while the salinities are between 0.6mg/l for BRS 3B and 0.9mg/l for SHA 2A soil samples. Soil sample SHR 3A has the highest resistivity measurement of 32.Ωm, while SHR 2A soil sample has the lowest of 6. Ωm. from the EC data the signal strength of EC measurements decreases with soil depth and most of the EC values falls within the range of 20 - 80 (µs/cm) which is the optimum level for most plants, usually indicates well - fertilized soils and salt sensitive plants may be insured.
