Loblolly Pine Stand Fertilization at Mid-rotation to Increase Small and Large Sawtimber Volume

A pine tree fertilizer study was established in Twiggs County, Georgia in 2013. The thinned loblolly pine stand showed P and K deficiencies based on soil sampling in March 2013 and leaf area index (LAI) estimation in August 2013 appeared to indicate N needs. The fertilizer trial (with three replications in a randomized complete block design) consisted of four fertilizer treatments applied in Feb 2014 i. e.

There are over 500,000 family forest landowners in Georgia who own approximately 67% (24. 3 million acres) of the state’s 36 million acres of forested land. The family forest landowners in the southeastern United States own from 49% to 67% of the forestland.

Two fertilizer trials and an untreated control were established in 2004 near Bullard, Georgia, within a loblolly pine tree stand planted in 1978 and thinned in 2002-03. Fertilizer treatments examined NP, NPK and NPKSCu fertilization effects in one trial and NP, NPCu, NPKCu, and NPKSCu fertilization effects in a second trial. The one-time fertilizer applications were applied in February 2005. Fertilizer levels applied were 200 lb N, 50 lb P, 80 lb K, 60 lb S, and 5 lb Cu/A.

Two fertilizer trials and an untreated control were established in 2004 near Bullard, Georgia, within a loblolly pine tree stand planted in 1978 and thinned in 2002-03. The objectives of the study were to: quantify the magnitude and duration of wood volume response to various fertilizer combinations,. determine changes in product class distribution, . determine the cash flow and rate of return for each fertilizer combination compared to unfertilized control plots, and .

The University of Georgia (UGA) Warnell School of Forestry and Natural Resources (WSFNR) installed a replicated fertilizer study on Chuck Leavell’s Charlane Plantation, located in Twiggs County, Georgia, in 2005. Seven of nine thinned loblolly pine stands showed NP, NPK, NPKS, and copper (Cu) deficiencies based on soil and foliar sampling on February 27, 2004.

Many private non-industrial forest (NIPF) landowners are seeking good economic returns to forest management and many loblolly and slash pine plantations in the South have nutrient limitations. A fertilizer trial was installed in a randomized complete block design in two Charlane Plantation thinned loblolly pine stands with marginal fertility (planted in 1978) in Twiggs County, Georgia, in 2004.
