This study was carried out at Ivo, Ohaozara and Onicha
L.G.As. to compare selected chemical properties of soils in
those areas. Four replicates of soil samples were collected
in each L.G.A. at depths of 0 to 30 cm using soil auger.
These soil samples were used for the determination of soil
texture, soil pH, organic C, total N, C/N ratio, available
P, exchangeable K and cation exchange capacity. Data
collected were analysed using standard error and coefficient
of variance. Results of the study showed that the soils of
the three L.G.As were sandy loam. The pH of soils studied
were all strongly acidic, and the order of the increase is
Ivo=Ohaozara<Onicha. The lowest organic C value of 1.26%
recorded at Onicha was lower than that of Ivo and Ohaozara
by 15% and 61% respectively. The order of increase in total
N and C/N ratio is Ohaozara >Ivo>Onicha. Onicha recorded the
highest available phosphorus value of 16.65mgkg-1 whereas
the lowest available P value of 13.58mgkg-1 was observed at
Ivo. Apart from Onicha which recorded 0.31 Cmol(+)kg-1 value
of exchangeable K, the values of exchangeable K observed in
the other two L.G.As. were below 0.20 Cmol(+)kg-1 regarded
as the critical limit of exchangeable K in soils. The
highest CEC value of 7.90 Cmol(+)kg-1 recorded in Onicha was
higher than that of Ivo and Ohaozara by 29% and 17%
respectively. These soils were strongly acidic and low in
plant nutrient, therefore, the application of lime, organic
and inorganic fertilizers is indispensable for optimum crop
performance in them.
Key Words: Chemical properties, fertilizer,
infertility and productivity.
