Abstract
This Gmelina arborea plantation was established on Tropudults since 1976 to supply raw material to a Newsprint Manufacturing company in Nigeria. The main objective of this study was to investigate the native fertility status and recommend management strategies of this Tropudults sustaining the plantation. Profile pits were dung at the crest, middle slope and valley bottom. Core samples were collected for physicochemical analysis. All the profiles had coarse texture. Bulk density ranged between 0.75 - 1.25g cm-3 that do not hinder root penetration. Porosity ranged from 53 – 73 % hence best for agricultural soils, while pH was acidic ranging from 4.51 – 4.80. Organic matter value of 2.84 % and 2.24 % for surface horizon of middle slope and valley bottom respectively were considered medium whereas that of the crest was considered low (1.12 %). The major nutrients; nitrogen, phosphorus and potassium (NPK) were rated below critical levels (N Keywords : Gmelina arborea, Tropudults, fertility status, humid tropics, Nigeria.
