Short summary
Eucalyptus plantations produce large extensions of fine roots that release energy-rich organic compounds into the soil, causing an increase in the number of microorganisms that degrade soil organic matter and release N to the trees, in the so-called rhizosphere priming effect. In order to estimate the quantitative importance of this phenomena, a mechanistic model was elaborated – the ForPRAN. It has been estimated that rhizosphere cycling can supply about 24.6 % of N accumulated in Eucalyptus.
