Book Harvest Intensity and Competing Vegetation Control Have Little Effect on Soil Carbon and Nitrogen Pools in a Pacific Northwest Douglas fir Plantation

Download or read book Harvest Intensity and Competing Vegetation Control Have Little Effect on Soil Carbon and Nitrogen Pools in a Pacific Northwest Douglas fir Plantation written by Erika J. Knight and published by . This book was released on 2013 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing demand for timber as well as current interest in the use of woody biomass for energy and chemical production may result in higher quantities of organic matter removal from plantation forests than currently occurs during harvesting. Two practices that can increase the yield of woody biomass from a harvest site are (1) the application of herbicides to control competing vegetation and improve crop tree growth and (2) the removal of branches and foliage (slash) in addition to the bole during harvest. The potential of these practices to change pools of soil carbon and nitrogen necessitates an evaluation of how management practices affect soil quality and carbon sequestration. In this study, soil carbon and nitrogen were measured to a depth of one meter in a 12-year-old Douglas-fir (Pseudotsuga menziesii) plantation at the Fall River Long-term Soil Productivity site in western Washington. The effects of vegetation control (bole-only harvest with versus without annual herbicide application, BO+VC vs. BO-VC) and harvest intensity (bole-only harvest with vegetation control versus total tree plus harvest with vegetation control, BO+VC vs. TTP+VC) on soil carbon and nitrogen were compared. Forest floor and mineral soil samples in six depth increments (forest floor, 0-15 cm, 15-30 cm, 30-45 cm, 45-60 cm, and 60-100 cm) were collected at 12 years following planting of seedlings. Carbon and nitrogen concentrations for the forest floor and the fraction of mineral soil

Book Impacts of Forest Harvesting on Long Term Site Productivity

Download or read book Impacts of Forest Harvesting on Long Term Site Productivity written by W.J. Dyck and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Energy Agency Bioenergy Agreement was initiated as the Forestry Energy Agreement in 1978. It was expanded in 1986 to form the Bioenergy Agreement. Since that time the Agreement has thrived with some fifteen countries (Austria, Belgium, Canada, Denmark, Finland, Italy, Japan, Netherlands, New Zealand, Norway, Sweden, Switzerland, United Kingdom, United States and the CEC) currently being signatories. The objective of the Agreement is to establish increased programme and project cooperation between the participants in the field of bioenergy. The environmental consequences of intensive forest harvesting have been the subject of intense interest for the Agreement from its initiation. This interest was formulated as a Cooperative Project under the Forestry Energy Agreement in 1984. It developed further under each of the subsequent three-year Tasks of the Bioenergy Agreement (Task III, Activity 3 "Nutritional consequences of intensive forest harvesting on site productivity", Task VI, Activity 6 "Environmental impacts of harvesting" and more recently Task IX, Activity 4 "Environmental impacts of intensive harvesting". The work has been supported by five main countries from within the Bioenergy Agreement: Canada, New Zealand, Sweden, UK, and USA. The continued work has resulted in a significant network of scientists work ing together towards a common objective - that of generating a better under standing of the processes involved in nutrient cycling and the development of management regimes which will maintain or enhance long term site productivity.
