Exploring growth enhancing rhizospheric microorganisms for silviculture of Neolamarckia cadamba

Neolamarckia cadamba (N. cadamba) is an indigenous timber tree species that was selected to rehabilitate degraded forest lands in Sarawak. Application of chemical fertilisers in forest rehabilitation is a standard practice. However, negative impacts of chemical fertilisers on environments and human health are always raised up as public concerns. Plant growth enhancing microorganisms found in the rhizospheres could be an environmental-friendly alternative to support growth of N. cadamba on degraded forest lands. They could be formulated into commercial biofertilisers to reduce usage of chemical fertilisers in the future forest rehabilitation activities.
