“…Reductions in fertilizer applications on a regional scale are likely a result of high material prices [33]. At the same time, urea prices (the most common form of nitrogen used in forestry application) can fluctuate by large amounts in relatively short periods of time [34].…”

Abstract:We examined three hypotheses in a nutrient dose and application frequency study installed in juvenile (aged 2-6 years old) Pinus stands at 22 sites in the southeastern United States. At each site, eight or nine treatments were installed where nitrogen was applied at different rates (0, 67, 134, 268 kg ha −1 ) and frequencies (0, 1, 2, 4 and 6 years) in two or four replications. Phosphorus was applied at 0.1 times the nitrogen rate and other elements were added as needed based on foliar nutrient analysis to insure that nutrient imbalances were not induced with treatment. Eight years after treatment initiation, the site responses were grouped based on texture and drainage characteristics: soil group 1 consisted of poorly drained soils with a clayey subsoil, group 2 consisted of poorly to excessively drained spodic soils or soils without a clay subsoil, and group 3 consisted of well-drained soils with a clayey subsoil. We accepted the first hypothesis that site would be a significant factor explaining growth responses. Soil group was also a significant factor explaining growth response. We accepted our second hypothesis that the volume growth-cumulative dose response function was not linear. Volume growth reached an asymptote in soil groups 1 and 3 between cumulative nitrogen doses of 300-400 kg ha −1 . Volume growth responses continued to increase up to 800 kg ha −1 of cumulatively applied nitrogen for soil group 2. We accepted our third hypothesis that application rate and frequency did not influence the growth response when the cumulative nitrogen dose was equivalent. There was no difference in the of nitrogen was applied as four applications of 67 kg ha −1 every two years or as two applications of 134 kg ha −1 every four years. Clearly, the sites examined here were limited by nitrogen and phosphorus, and applications of these elements to young stands effectively ameliorated these limitations. However, there were differences in the response magnitude that were related to soil texture and drainage. Juvenile fertilizer applications resulted in high stocking levels early in the rotation; this condition should be considered when undertaking juvenile fertilization programs.

“…Given the size of the actively managed loblolly pine plantation resource and its responsiveness to silviculture, management can be modified to increase regionwide ecosystem carbon sequestration, especially when gains in ecosystem carbon align with increased stem growth or efficiency of fertilizer use. For instance, an additional 8 Tg CO2 equivalents year is sequestered due to application of N and P fertilizer to loblolly pine plantations [9].…”

Abstract:The future climate of the southeastern USA is predicted to be warmer, drier and more variable in rainfall, which may increase drought frequency and intensity. Loblolly pine (Pinus taeda) is the most important commercial tree species in the world and is planted on ~11 million ha within its native range in the southeastern USA. A regional study was installed to evaluate effects of decreased rainfall and nutrient additions on loblolly pine plantation productivity and physiology. Four locations were established to capture the range-wide variability of soil and climate. Treatments were initiated in 2012 and consisted of a factorial combination of throughfall reduction (approximate 30% reduction) and fertilization (complete suite of nutrients). Tree and stand growth were measured at each site. Results after two growing seasons indicate a positive but variable response of fertilization on stand volume increment at all four sites and a negative effect of throughfall reduction at two sites. Data will be used to produce robust process model parameterizations useful for simulating loblolly pine growth and function under future, novel climate and management scenarios. The resulting improved models will provide support for developing management strategies to increase pine plantation productivity and carbon sequestration under a changing climate.

“…For example, Scott and Perry (2008) document emissions of 0.09 tonnes of carbon equivalent per acre from manufacture and 0.003 tonnes of carbon equivalent from transportation and application of fertilizer. However, the available evidence suggests that emissions from production and transportation are low relative to the additional sequestration generated by fertilization (Scott and Perry 2008;Albaugh et al 2012).…”

This research uses an econometric model to analyze the factors affecting nonindustrial private forest landowners' choice of intermediate forest management practices, and to examine how these choices might change in response to incentives for carbon sequestration. We also use parameter estimates to simulate the carbon sequestration potential for different combinations of management practices, and compare the effectiveness and costs of carbon sequestration-based and practice-based incentive payment schemes. Our results suggest that incentive payments increase the probability that desirable combinations of management practices are adopted. Simulation results indicate that incentives targeting fertilization yield the highest carbon sequestration potential, and that a carbon-based payment scheme produces higher carbon sequestration than a practice-based payments scheme.
