Available in PDF, EPUB and Kindle. Book excerpt: This book responds to the widespread recognition among experts that our educational system needs to change in order to provide the skills and knowledge necessary to ensure the future vitality of U.S. agriculture. Understanding Agriculture focuses on agricultural literacy (education about agriculture) and vocational agricultural education (education in agriculture). The section on agricultural literacy addresses the teaching of science through agriculture, teacher education and training, model educational programs, community support, and agricultural career exploration programs. Vocational agricultural education is examined in terms of program enrollment, availability and content, supervised occupational experiences, the Future Farmers of America program, and teacher education and supply.

Available in PDF, EPUB and Kindle. Book excerpt: The Forest Regeneration Manual presents state-of-the-art information about current regeneration practices for southern pines in the United States. Over 1.2 billion seedlings of five major species -- loblolly, slash, longleaf, sand, and shortleaf -- are planted each year. In 22 chapters, the Manual details fundamental steps in establishing successful young pine plantations: regeneration planning, including economic and legal aspects; regeneration harvest methods; propagation by seed and vegetative techniques; bareroot and container seedling culturing in the nursery; measures of seedling quality; site potential; -- environment, associated vegetation, soils; matching species to sites; site preparation -- mechanical and chemical methods, fire, fertilization; seedling handling before planting; planting practices and measures of regeneration success; promoting early plantation growth and management of competing vegetation, insects, disease, and wildlife.

Download or read book Prescribing Regeneration Treatments for Mixed Oak Forests in the Mid Atlantic Region written by U. S. Department U.S. Department of Agriculture and published by CreateSpace. This book was released on 2015-02-14 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This shift in species composition in mixed-oak forests is often undesirable to natural resource professionals and society as a whole because oaks have both ecological and economic value (Smith 2006). Throughout the mid- Atlantic region, oaks grow on a variety of sites: from chestnut oak on xeric ridges to northern red oak on mesic lower slopes (Fig. 1.3). Oaks are long lived, quite resistant to rot, and grow to large sizes. These characteristics indicate that, once established, oak forests are relatively stable plant communities (Smith 2006). Once they achieve canopy dominance, oaks likely will persist for decades to centuries as they readily withstand insect outbreaks, lightning strikes, wind events, and ice storms. When damage does occur, the ability to compartmentalize rot helps ensure their continued survival (Shigo 1984). Injury sites may become cavities which, in turn, become dens for wildlife.
