Growth of Slash, Loblolly, and Longleaf Pines on Cultivated Sites
An earlier article reported the rapid height growth of slash and loblolly pines planted in 1956 on cultivated plots.1 A longleaf plantation, established in 1958 under similar site and treatment conditions, affords an opportunity to compare longleaf growth with that reported for the two other pine species. In March 1958, 1-0 longleaf seedlings were bar-planted on an old field that had been in sod about 25 years, but had recently been plowed and disked. The soil is a deep fine sandy loam in the Orangeburg series. Spacing was 10 by 10 feet. In the first 4 years, the plantation was cultivated three or four times per year with a tandem disk harrow, and the weeds near the trees were hoed by hand. In the first 2 years the trees were sprayed to control brown- spot needle blight.
