Suitability Assessment of Soils Supporting Oil Palm Plantations in the Coastal Plains Sand, Imo State, Nigeria

Ukaegbu E.P.*, Osuaku, S.K., Okolo, C.C.

Due to the declining yield of Oil palm, soils of the coastal plains sand of Imo State supporting oil palms were evaluated. A bulked sample was taken from each of the ten sites studied, at 0 – 20cm and 20 – 40cm depths and analysed in the Laboratory. Soils textures were dominated by sandy loam at the surface, but sandy clay loam at the subsurface. Ranges of values of parameters at the topsoil were:...
