We examined the effects of cultural intensity (operational and intensive), planting density (741, 1483, 2224, 2965, 3706 and 4448 trees ha−1) and their interaction on aboveground biomass accumulation and allocation for 12-year-old loblolly pine (Pinus taeda L.) trees in the Upper Coastal Plain and Piedmont of the southeastern United States. Cultural intensity significantly affected accumulation of stem, bark, dead-branch and total aboveground biomass and biomass allocation in the dead-branch component. Accumulation of total aboveground biomass and each component biomass and biomass allocation to each component were significantly affected by planting density. The only significant culture × density interaction was for dead-branch biomass accumulation.
► We quantify cultural intensity and planting density effects on loblolly pine tree biomass.
► Increased culture increased stem, bark, dead-branch and total aboveground biomass per tree.
► Component and total aboveground biomass per tree were greater at low than at high densities.
► Culture affected only dead-branch allocation and density affected allocation to each component.
