This study was conducted to assess the growth and carbon storage of Tectona grandis (Verbenaceae) and to evaluate the influence of chemical properties and moisture of soil on teak (Tectona grandis) growth in Afrensu Brohuma Forest Reserve, Ghana. Teak growth was classified as good (1), medium (2) and poor growth (3) and aboveground biomass and carbon storage were estimated. The aboveground carbon storage and chemical properties of soils in the study sites and those of other teak plantations and different tree species were compared and the relationships between the volumetric water content of soils and growth class of teak were determined. Precipitation seemed to influence height and aboveground biomass of teak. The soil total N and exchangeable K in the study sites were lower than those in other teak plantations in the region. The volumetric water content in soils of most Class 1 sites was significantly higher than that in Class 2 sites. Consequently, teak growth was probably affected by some chemical properties and moisture status of soils in the present study sites. It is therefore necessary to preserve the teak plantation on long term to achieve efficient carbon storage in a plantation for carbon projects.
