Growth response of longleaf pine (Pinus palustris Mill.) seedlings to fertilization and herbaceous weed control in an old field in southern USA

The effect of weed control and fertilization on survival and growth of four pine species in the Virginia Piedmont

“…Loblolly pine was taller than the hardwoods in the fertilized plots, and consequently had the greatest survival at age 5, averaging around 65%. Numerous research studies have reported similar findings in terms of crop tree survival when fertilizer is applied without controlling the competing vegetation (Haywood and Tiarks, 1990;Clason, 1993;Ramsey et al, 2001). Table 2 Soil pH, total C, total N, mineralizable N, and extractable nutrients in surface soil from pine plantations in the Virginia Piedmont five growing seasons after planting as affected by weed control and fertilization Treatment pH Loblolly pine exhibited the fastest growth among the pine species in this study.…”

Effects of silvicultural treatments on survival and growth of trees planted on reclaimed mine lands in the Appalachians

“…Fertilization decreased survival of all species at the WV and OH sites. Fertilization can stimulate the growth of competing vegetation, which can detrimentally affect survival (Ramsey et al, 2001). At both WV and OH, a well established pasture dominated by fescue was present at the start of the study.…”

Fine root production and carbohydrate concentrations of mature longleaf pine (Pinus palustris P. Mill.) as affected by season of prescribed fire and drought

“…Fortunately, regeneration research has recently identified successful approaches to establish longleaf pine (Barnett and McGilvray 1997;Boyer 1989;McGuire et al 2001;Ramsey et al 2003;Rodríguez-Trejo et al 2003), and fire is now considered an effective longleaf pine management tool (Brockway and Lewis 1997;Brockway and Outcalt 2000;Gilliam and Platt 1999;Haywood et al 2001). As a result, successful restoration of longleaf pine to portions of its natural range is ongoing.…”
