Individual-Tree Diamter Growth Models for Quantifying Within-Stand Response to Nitrogen Fertilization Item Info

Diameter-increment models for nitrogen-fertilized stands were developed using data from permanent research plots in northern Idaho. The equations partially resembled PROGNOSIS model diameter growth formulations. Results indicated that both initial tree size and initial stand density produced significant interactions with treatment to explain an individual tree's response to fertilization. Larger trees in a stand showed more fertilization response than smaller trees. Furthermore, individual trees in low-density stands showed more fertilization response than those growing in high density stands. These diameter increment predictive equations were formulated to be compatible with individual-tree distance-independent simulation models.
