ABSTRACT
The objective of this study was to evaluate how the fertilizer composition, type and application
method contribute to the initial growth of Pinus taeda applied at planting. Seedlings from an
open‑pollinated seed orchard of Pinus taeda were planted on a Humic Dystrudepts soil containing
15 treatments of fertilizer application at planting. Basal diameter (immediately above ground – about
5 cm) and total height were measured on all live plants after six, 12 and 42 months. The basal
diameter at six and 12 months ranged from 0.49 to 0.63 cm and 1.64 to 2.15 cm, respectively.
The height at six and 12 months ranged from 0.49 to 0.64 m and 0.77 to 1.01 m, respectively,
indicating that fertilizing improved this characteristics in ~30%. Fertilizer composition, type
and application method contributed to the first year of growth of Pinus taeda. Nevertheless,
fertilization response disappeared after 42 months.
