Abstract

Four spacings of loblolly pine trees (6 by 6 ft, 8 by 8 ft, 10 by 10 ft, II by 12 ft) were studied for 15 years at the Calhoun Experlmental Forest ne.ar Union, South carolina. The two wider spacings at 15 years produced trees of greater height, larger diometer, and more sawtimber voll.tne while the two narrower spacings favored bds4l area growth and total cubfc volume production. More merchantable cord volume was produced at the 8 by 8 ft spacing. The study results should offer some guidance to the landowner in the Piedmont In choosing a spacing for planting to meet his specific production needs.
