Reduction in nursery bed density for slash and loblolly pine seedlings can result in significantly improved growth of field plantings. With systematic control of seedbed density, both the morphological and physiological properties of southern pine seedlings can be altered. During the second growing season, loblolly and slash pine seedlings taken from low bed densities grew 5.1 and 3.3 inches taller, on the average, than did seedlings produced at high bed densities. Both species after four growing seasons indicated that this growth differential between seedlings of low and high density beds had continued in favor of those grown at the lower densities.

The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
