註釋
Longleaf pine can be profitably grown as a forest crop on farms as well as on large industrial holdings throughout most of the Southern Coastal Plain. The tree is able to grow well even on poor sandy soils, withstands fires with less injury than other pines, and produces both naval stores and high-grade timber. Cattle grazing can be combined with timber production in longleaf forests to enable farmers to make more profitable dual use of their land. This bulletin offers suggestions to farmers and other timberland owners for establishing and managing longleaf pine.
