The region from east Texas to the Atlantic coastal plain is home to many thousands of acres of managed southern pine forests. This region is considered the “wood basket” of the world, producing more wood than any other country. To further increase wood production, research cooperatives between universities and the forest industry developed in this region, resulting in research plots being established that incorporate varying levels of nutritional control, species manipulation, levels of disturbance, and even intra-specific genetic control. These experimental plots provide a tremendous opportunity to address a number of applied and basic ecological questions. In collaboration with the Forest Biology Research Cooperative (http://www.sfrc.ufl.edu/fbrc/) at the University of Florida, my group works on a number of questions related to forest productivity, and the carbon and nutrient cycling of these ecosystems.
Some example issues we are working on-
What is the proper fertilization regime to increase forest production and carbon storage, but minimize ecosystem nutrient loss?
Is there significant variation in the C allocation to roots among loblolly pine families and their response to nutrition, and how does this variation affect growth and soil carbon cycling (USDA proposal, 2009-2012)?
Are there significant carry-over effects of weed control or fertilization on next rotation forest productivity?
