Book Synopsis Effects of Microsite Alteration on Soil Climate, Nitrogen Mineralization, and Establishment of Picea Glauca X Engelmannii Seedlings in the Sub-boreal Spruce Zone of West-central British Columbia by : Anne M. Macadam
Download or read book Effects of Microsite Alteration on Soil Climate, Nitrogen Mineralization, and Establishment of Picea Glauca X Engelmannii Seedlings in the Sub-boreal Spruce Zone of West-central British Columbia written by Anne M. Macadam and published by . This book was released on 1991 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Site preparation treatments are often used prior to the planting of clearcut forest lands to improve planter access and to increase the number and quality of planting spots. Most mechanical site preparation treatments alter the configuration and material composition of surface soil materials, and can have marked effects on soil properties important to seedling survival and growth. Effects of some of these treatments on soil moisture, soil temperature, rates of nitrogen mineralization, and the establishment of Picea glauca x engelmannii seedlings were examined on fresh, moist, and wet sites in the moist cold subzone of the Sub-boreal Spruce Zone in west-central British Columbia. Four types of microsite alteration were investigated: forest floor removal (spot scalping), soil mounds over inverted sections of forest floor (inverted mounds), mineral soil mounds over a mineral soil surface, and inversion of the forest floor and mineral soil in place. Soil temperature was monitored continuously and soil moisture weekly at the 10-cm depth in 16 combinations of site and microsite treatment during two growing seasons. The response of seedling height and diameter growth was monitored for three growing seasons. Effects of altering soil temperatures through mechanical treatments on rates of nitrogen mineralization were examined by incubating a standard soil material in a range of microsites created by six combinations of site and mechanical treatment. Effects of substrate quality and soil temperature on rates of nitrogen mineralization were examined in paired mounded and untreated spots in fresh, moist, and wet sites. In all sites, early growing season soil temperatures in the seedling rooting zone were substantially warmer in inverted mounds than in other treatments. Spot scalping increased temperatures slightly relative to controls in the fresh site, but had little or no warming effect on moist and wet sites. Inverted mounds became substantially drier than other treatments during periods of low rainfall, particularly in the fresh site. After three growing seasons, seedling height growth was greatest in inverted mounds, irrespective of site. Amounts of nitrogen mineralized in a standard soil material during incubation for 77 days in the field were significantly greater for samples placed in inverted mounds than for those placed in other microsite treatments. There was a significant positive correlation between amounts of nitrogen mineralized during field incubations and degree hour sums calculated for associated microsite treatments and sites. Both substrate quality and soil thermal regime affected rates of N mineralization in samples from paired mounded and untreated spots, and an interaction was observed between the two factors.

Book Synopsis The Supporting Roots of Trees and Woody Plants: Form, Function and Physiology by : A. Stokes
Download or read book The Supporting Roots of Trees and Woody Plants: Form, Function and Physiology written by A. Stokes and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication comprises the proceedings of the first International Conference devoted to the structural roots of trees and woody plants. 'The Supporting Roots - Structure and Function,' 20-24 July 1998, Bordeaux, France. The meeting was held under the auspices ofIUFRO WPS 2. 01. 13 'Root Physiology and Symbiosis,' and its aim was to bring together scientific researchers, foresters and arboriculturalists, to discuss current problems in structural root research and disseminate knowledge to an audience from a wide disciplinary background. For the first time in an international conference, emphasis was placed on presenting recent reseach in the field of tree anchorage mechanics and root biomechanics. The way in which tree stability can be affected by root system symmetry and architecture was addressed, as well as how movement during wind sway can influence the development and shape of woody roots. The role of different nursery and planting techniques was discussed, in relation to effects on root system form and development. Root response to different environmental stresses, including water, temperature, nutrient and mechanical stress was addressed in detail. The structure and function of woody roots was also considered at different levels, from coarse to fine roots, with several papers discussing the interaction between roots and the rhizosphere. One of the conference highlights was the presentation of new methods in root research, by a series of workshops held at LRBB-INRA, Pierroton, on the northern border of the Gascony forest.

Book Synopsis Conifer Seedling Mineral Nutrition by : R. van den Driessche
Download or read book Conifer Seedling Mineral Nutrition written by R. van den Driessche and published by CRC Press. This book was released on 1990-12-13 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conifer Seedling Mineral Nutrition provides a comprehensive review of conifer seedling mineral nutrition and its significance to forestry. The book covers relationships between mineral supply and uptake; the effects of nutrition on seedling growth; an integration of the ideas of T. Ingestad with classical growth analysis concepts; practical aspects of assessing nutrient status and details of fertilizing bare root and container nursery stock; and fertilizing vegetative propagules. The book also describes and illustrates Mycorrhizas, assessing their importance to plantation establishment in an analysis of recent papers reporting field trials. The effects of nutrients on stress resistance and establishment when applied in the nursery and while planting are discussed in the final chapter. It will prove useful to reforestation research workers, nurserymen, and silviculturalists and should be considered essential reading for forestry students.
Book Synopsis Analysis and Interpretation of the Research Microsite Projects in Alberta by : Kenneth M. Brown
Download or read book Analysis and Interpretation of the Research Microsite Projects in Alberta written by Kenneth M. Brown and published by . This book was released on 1995 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents results of a study of the effects of cultural and environmental factors on the survival, growth, and development of white spruce and lodgepole pine crop trees, deciduous competing vegetation, and herbaceous competing vegetation. The data were collected during the summers of 1992 and 1993 from 28 research microsite projects in Alberta. Controlled factors included type of mechanical site preparation, microsite planting position, planting stock type, and planting date. Response variables include various measures of crop tree survival, final size, and rate of growth; deciduous tree competitors; and shrub, forb, and grass competition. Analytical methods used include contingency table analyses, multivariate analyses of variance, multiple linear regression analyses, and a variety of exploratory graphic methods. The results indicate the influence of microsite position, stock type, and planting season on the performance of crop trees and competing vegetation.
