Soil drainage, spacing, and site preparation effects on height and stand volume growth in slash pine (Pinus elliottii Englm.) plantations in the Southeastern Coastal Plain of Georgia were analyzed. The moderately well-drained Orsino soil produced the best early height growth, but by age 25 ranked third and produced significantly shorter trees than those on Leon and Mascotte soils. Spacing had little effect on tree heights until late in the study when the 6x6-foot spacing resulted in reduced codominant and dominant tree heights. By age 25, the control, i.e., broadcast burn only, produced stand volumes and codominant and dominant tree heights similar to that on the more intensely prepared bed and harrow treatments on two of the four soil series. Culmination of mean annual increment occurred earlier on the better drained soils and on the more intensively prepared sites. Scalping proved detrimental to growth, producing inferior mean height and volume.
