Larry Morris


Dr. Morris is an authority in the area of forest soil productivity and management and in utilization of forestland for waste treatment and recycling. He recently served on the editorial board as the soils expert for two major volumes (The Forests Handbook, 2001, Vol. 1 and Vol. 2. Blackwell Science, Ltd., London; and The Encyclopedia of Forest Sciences, 2004, Elsevier Ltd., London). He has authored or co-authored 8 book chapters, 30 journal articles, 30 published proceedings articles as well as many project reports and technical reviews. His research combines an interest in long-term forest productivity with waste recycling and utilization. Between 1995 and 1999 he served as project leader for an industry-funded study of pulp mill waste utilization in loblolly pine plantations. Currently, he is conducting research on the potential benefits of land application of char produced during pyrolysis on soil conditions and tree growth.

Dr. Morris's plays a leadership role in international programs in soil and forest resource management at UGA. He has served as major academic advisor to graduate students from Austria, Brazil, China, Great Britain, New Zealand, the Philippines and Sri Lanka. He is particularly active in Brazil where he leads an exchange program between the University of Georgia and three Brazilian Universities: the Federal University of Viçosa, Federal University of Curitiba and the Federal University of Tocatins. In 2004, he was part of a team of university scientists and businessmen that were awarded a Fome Zero grant by the Brazilian oil company, Petrobras, to help communities in the Amazon near Belem develop food and energy production alternatives. He also works with university faculty and consultants on a phyto-remediation project near Sao Paulo for Shell Oil International.

Dr. Morris teaches courses at both the undergraduate and graduate level. He has directed seniors in the Warnell School in their capstone course (Senior Project in Forestry and Natural Resources) for 20 years. He also teaches courses to undergraduate and graduate students in forest soil management and urban tree management and offers a graduate-only course in forestland treatment of waste and wastewater. Dr. Morris developed an honors seminar titled "The Industrialized Ecosystem" which, among other things, challenges students to think about the role that soils play in crop and fiber production, waste processing and a sustainable society. Finally, he offers a student abroad to Brazil on alternate years that includes visits to ethanol production facilities and plantation forests in the south of the country, as well a boat voyage that visits communities living along the Amazon River in the north of the country.
