Woody leaf biomass production (dry matter pounds/acre) of individual species or species groups after implementation of understory fertilization (fert), prescribed burning (burn), and prescribed burning with understory fertilization (burn/fert) in two closed-canopy hardwood stands (Rocky River Hunting Club [RR] and Ames Plantation [AP]) in Tennessee, July–August 2005. Asterisks indicate significant burning × fertilization interaction at P < 0.01. Within the row, means are not different (P > 0.05) if followed by the same letter. Raw means are reported for red oak group, but analysis was conducted on transformed data.
