Download or read book Calcareous Soils Their Properties and Potential Limitations to Conifer Growth in Southeastern British Columbia and Western Alberta written by Barbara Ellen Kishchuk and published by Canadian Forest Service, Northern Forestry Centre. This book was released on 2000 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a review of published literature on calcareous soils and their role in the productivity of coniferous forests in southwestern British Columbia and western Alberta. Definitions, origins, and properties of calcareous soils are described. Processes contributing to growth limitations on calcareous soils are reviewed. Chemical properties of calcareous soils may give rise to tree nutrition problems or other metabolic disturbances. Physical properties of calcareous soils may also affect tree growth through compacting or cementing effects. Factors controlling productivity on calcareous soils are discussed with particular reference to coniferous species in western Canada. Depth to carbonates in the soil profile appears to be an important factor in the establishment and productivity of coniferous stands in western Canada. Forest practices resulting in displacement of calcareous subsoils and implications of calcareous soil displacement are identified. Although instances where decreases in forest productivity on calcareous soils have been identified, calcareous soils do not appear to have a consistently adverse effect on productivity. Attributes of soils and other site factors must be identified to determine the role of calcareous soils in stand establishment and productivity.

This book was released on 2009 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general objective of this study was to determine if calcium carbonate was a limiting factor in the growth of 20-year old interior spruce. The specific objectives were: to describe the soil conditions for the acidic (eka) and calcareous (ekc) soil groupings for the progeny test sites studied by Xie et al. (1998); to determine the relationship of 20-year-old interior spruce growth with depth to carbonates at two calcareous sites within the former Invermere Forest District; to determine the relationship of soil and foliar chemistry to interior spruce growth at the two calcareous sites; and to compare the foliage chemistry of interior spruce growing on calcareous soils to interior spruce growing on a non-calcareous soil.--Document.

This book was released on 2012 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unpredictability surrounding climate change has prompted questions about forest productivity and biodiversity. Uncertainties exist regarding the future composition of current ecosystem envelopes, including ICH forests. This study investigated the growth rates of common conifer species under different levels of canopy cover and soil moisture north of Revelstoke, BC. Generally all species showed a negative relationship to increased cover regardless of the soil moisture with the exception of western redcedar (Thuja pilcata Donn ex D. Don) (Cw). Average leader growth of Cw was greater on wet sites with low and moderate levels of canopy cover compared to dry sites. The results of this study suggest that harvest plans can optimize regeneration success by increasing residual stands and planting species in a variety of site conditions to successfully manage potential climate impacts. The establishment and growth of Cw should be encouraged so that the characteristics of the inland rainforest are maintained.

Download or read book Forest Soils written by Khan Towhid Osman and published by Springer Science & Business Media. This book was released on 2013-12-12 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest soil characteristics are not only unique but their interpretation also differs from cropland soils. Just as there are diverse forest types, there are many soil variants that need different management. Today, forest plantations are being intensively managed for profitable timber, pulpwood and energy production. Site selection, species selection, site productivity evaluation, silvicultural treatments, and soil amendments need crucial soil information. This book provides a comprehensive overview of the physical, chemical and biological properties of forest soils and their implications on forest vegetation. Topics discussed include: major forest types of the world and their associated soils; forest biomass and nutrient dynamics; organic matter turnover and nutrient recycling; forest soil disturbance; forest soil and climate change; and forest soil management and silvicultural treatments.
