Dr. Mattia Terzaghi is an Environmental and Applied Botany researcher at the Uni-versity of Salerno, Italy. He received a Ph.D. in Environmental Science at the University of Insubria, Varese, Italy. His research is centred on plant roots. He studied the morphologi-cal and physiological effects of forest management on roots development, water stress re-sistance of Mediterranean forest ecosystems and oak seedlings with a particular attention for growth dynamics of root systems, seedling germination and growth under different light spectra, use of image analyses to measure plant traits. His current main study deal with the effects of different soil conditioners (urban compost—biochar) on olive tree growth (and their productivity) and biotic/abiotic soil characteristics.
