The IDForest team has begun monitoring the inoculations carried out at the spanish demo sites. Root samples have been collected from all inoculated trees with both Pisolithus tinctorius and Tuber aestivum and T. borchii. In the coming days samples will be collected in the Italian demo sites. The objective will be to observe under microscope the presence of mycorrhizas in the IDForest laboratory and determine the degree of evolution of the inoculations.
