Trees from fertilization experiments in four slash pine (Pinus elliottii Engelm. var. elliottii) and two loblolly pine (P. taeda L.) stands were subjected to stem analysis. The stands were unthinned and were between 13 and 25 years old at time of treatment. Profiles of radial width and cross-sectional area were examined to determine whether fertilization changed stem form. Proportionally greater growth on the upper stems of fertilized trees in the years immediately after treatment led to underestimating response with conventional volume equations. After 5 or more years, however, form was little changed and a single volume equation was appropriate for both fertilized and unfertilized trees.² South. J. Appl. For. 12(2):90-97.
