Quantity and timing of needlefall in N and P fertilized loblolly pine stands
Needlefall quantity and timing were examined for 1.5 years on three loblolly pine ( Pinus taeda L.) stands from a nitrogen (N) and phosphorus (P) fertilization field study. Needlefall biomass increased following N fertilization on the two N-deficient stands. Needlefall biomass increased by as much a...

Pinus taeda L.) stands from a nitrogen (N) and phosphorus (P) fertilization field study. Needlefall biomass increased following N fertilization on the two N-deficient stands. Needlefall biomass increased by as much as 75% (from 2088 to 3660 kg ha
−1 year
−1) on one of these stands, but on average increases were about 30%. On a high N quality stand, there was no needlefall biomass response to N fertilization. Phosphorus had no effect on needlefall biomass in any of the three stands. Across all stands, needlefall biomass was unrelated to stocking (as measured by basal area), but significantly correlated (
