Feature
The unseen depths of soils - how plant growth promoting microbes may advance commercial forestry practices

A. C. Tizzard , M. Vergnon and P. W. Clinton



Advances in the broad research fields of plant physiology, microbiology and molecular biology have focused attention on some exciting opportunities to co-ordinate and integrate research on those resources critical to maintaining the productive capacity of forest soils. In the past research has focused on the role of nutrients in determining levels of productivity. However, closer attention should be paid to the role of interactions between soil organic matter, nutrients and microbially produced phytohormones in controlling plant physiological and ecosystem level processes. New insights into rhizosphere function and its impact on tree growth and wood properties may lead to new management strategies. This will sustain the productive capacity of soils and lead to the sustainable production of a range of biomaterials with designer specified properties.
