Available in PDF, EPUB and Kindle. Book excerpt: Fertilization of pine plantations has increased dramatically in the last decade. Over 600,000 hectares are being fertilized annually to overcome chronic widespread nitrogen (N) and phosphorus (P) limitations. However, responses to fertilization vary widely since specific responses after fertilization for any particular stand will be the result of complex interactions of nutrients and rates applied, stand and site conditions at time of application, years since application, and climatic conditions after application. Stand, soil and forest floor (FF) responses to fertilizations were assessed at three different sites located in the 'flatwoods' area of southeast Georgia and northeast Florida after five years of repeated fertilizer additions. Significant leaf area index (LAI), stemwood growth and FF responses were found at all three sites. Leaf area index was double for some treated plots as compared to control plots (from 1.4 to 3.0), five year cumulative growth on treated plots almost tripled that of the control plots (32 to 89 cubic meter per hectare). Soil N availability increased dramatically soon after fertilization however, it decreased few months after application. Several nutrients affected growth at these three sites, N and P at all three sites and potassium (K) and manganese (Mn) at the Georgia study sites. Factors affecting growth efficiency (GE) of loblolly pine plantations across the southeast were examined using 86 studies sites with different climatic, edaphic and stand conditions. Two modeling approaches were developed, one where GE would change with levels of LAI (non-linear using Gompertz model) and a second where GE was independent of the level of LAI (linear model), in both cases significant reduction in RMSE (>200%) was achieved when parameters in the models were allowed to be functions of edaphic, climatic and stand characteristics. In conclusion, GE is a dynamic rather than static stand parameter; it changes with stand age, drainage, soil texture a.

Download or read book Fertilizer Responses of Longleaf Pine Trees Within a Loblolly Pine Plantation written by Peter H. Anderson and published by . This book was released on 2009 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Evidence is mixed on how well longleaf pine (Pinus palustris Mill.) responds to increased soil nitrogen via fertilization. We examined growth and physiological responses of volunteer longleaf pine trees within an intensive loblolly pine (P. taeda L.) fertilization experiment. Fertilizer was applied annually following thinning at age 8 years (late 1992) at rates tailored to maintain a high needle nitrogen concentration. We measured the annual growth of 20 volunteer longleaf pine trees per treatment. We took bimonthly gas exchange measures on 12 longleaf pine trees per treatment from June 1999 through June 2000, after which we estimated carbon isotope discrimination and foliar nitrogen concentration on foliage. The impact of fertilization in both growth and gas exchange was dependent on competition for light with neighboring loblolly pine trees. When fertilized longleaf pine trees were separated into categories with respect to being dominant or suppressed (relative to the loblolly pine trees) dominant-fertilized trees had the lowest carbon isotope discrimination, increased photosynthesis, and decreased stomatal conductance, indicating greater water use efficiency in these trees. Compared to loblolly pine, longleaf pine growth is restricted less by poor soil nutrition. However, early rotation longleaf pine appears to have the potential to increase growth rate via fertilization to almost the same extent as loblolly pine.S3.

Book excerpt: "Southern forests provide innumerable benefits. Forest scientists, managers, owners, and users have in common the desire to improve the condition of these forests and the ecosystems they support. A first step is to understand the contributions science has made and continues to make to the care and management of forests. This book represents a celebration of past accomplishments, summarizes the current state of knowledge, and creates a vision for the future of southern forestry research and management. Chapters are organized into seven sections: "Looking Back," "Productivity," "Forest Health," "Water and Soils," "Socioeconomic," "Biodiversity," and "Climate Change." Each section is preceded by a brief introductory chapter. Authors were encouraged to focus on the most important aspects of their topics; citations are included to guide readers to further information."
