This paper presents a project that examined the effects of intensive management and genetic selection of loblolly pine (Pinus taeda) on soil CO2 efflux and C cycling. Two field installations in Florida at Gainesville (Site A) and Sanderson (Site B) of two families of loblolly pine, one 'fast' and one 'slow' grower, were studied in a replicated, family block design with two levels of nitrogen and phosphorus fertilization, high and low culture. Results from these studies suggest that with increasing levels of fertilization, belowground allocation and likely C inputs to the soil were reduced.
