The Silviculture of Trees Used in British Forestry

by Peter Savill

British woodlands and forests are often located on sites and in regions that are marginal for agriculture; many are at high elevations and exposed, with short growing seasons. Wherever forests are located, site and climatic conditions must dictate species choice in forest management. This book provides a detailed guide to the biological suitability of different sites and soils for all important native trees and the most extensively used exotics. Apart from physical difficulties such as steepness and stoniness, forest soils also frequently have problems associated with them. They can be waterlogged or drought-prone, suffer from extremes of acidity or alkalinity, or have compacted layers. The book provides information on species' suitability for different purposes. It includes details of species' origin and introduction (where applicable), as well as their climatic and soil requirements and other silvicultural characteristics. Information about provenance, yield and timber is also provided. Fully updated throughout, this 3rd edition puts more emphasis on species suitable for changing climatic conditions, with accounts of several species that may become more prominent in British forests: including several silver firs, hickories, eucalypts, spruces, poplars and wingnuts. The book concludes with simple keys for identifying the trees most likely to be encountered in British forests. It is an essential resource for students, researchers and forestry professionals.

Silvohorticulture: A grower's guide to integrating trees into crops

by Andy Dibben Ben Raskin

"Dibben and Raskin offer an insightful, inspiring but also exceptionally practical guide to integrating trees into annual cropping systems. . . in this book we see how the phrase 'the sky’s the limit' has never been more applicable."—Jesse Frost, author of The Living Soil Handbook An invaluable handbook for farmers, growers, and gardeners, Silvohorticulture is the first book to offer a detailed, practical guide on how to effectively integrate trees with vegetable growing, offering information previously known only in the foresting world. Drawing on the decades-long experiences of Ben Raskin and Andy Dibben, both of whom have designed and managed agroforestry systems and have extensive experience in commercial horticultural crop production, this is the definitive book on the interaction between trees and crops, covering the benefits of trees for edible crops and the potential for additional crops from trees, plus crucial new information on how to fit trees into complex crop rotations as well as manipulating access to light. Ben and Andy also reveal the latest research on how tree roots behave and, importantly, how that impacts your crops. Agroforestry can bring immense benefits to farmers and growers—not just optimizing yield, but also improving soil, managing pests and water, increasing biodiversity, and reducing costs. System design must be customised to each grower’s requirements, and Silvohorticulture offers step-by-step detail that will allow you to manage your trees and crops successfully. "In this immensely practical guide, the authors provide the technical details towards integrating trees with vegetables and other crops, all while dispelling any preconceived notions that this idea reduces productivity or function. In fact, these systems might prove essential for farm resilience in a changing climate."—Steve Gabriel, author of Silvopasture

Silvopastoral Systems in Southern South America

by Pablo Luis Peri Francis Dube Alexandre Varella

This multi-authored volume contains peer-reviewed chapters from leading researchers and professionals in silvopastoral systems topic in Southern South America (Argentina, Chile and South Brazil). It is a compendium of original research articles, case studies, and regional overviews and summarizes the current state of knowledge on different components and aspects (pasture production, animal production, trees production, carbon sequestration, conservation) of silvopatoral systems in native forests and tree plantations. The main hypothesis of the book is that farmers have integrated tree and pasture/grassland species in their land use systems to reach higher production per unit of land area, risk avoidance, product diversification, and sustainability. These production systems also impact positively in main ecosystem processes. Management of these productive systems, Policy and Socioeconomic Aspects provide great opportunities and challenges for farmers and policy makers in our region. The book is unique on this subject in Southern South America and constitutes a valuable reference material for graduate students, professors, scientists and extensionists who work with silvopastoral systems.

The SimCalc Vision and Contributions

by Jeremy Roschelle Stephen J. Hegedus

This volume provides essential guidance for transforming mathematics learning in schools through the use of innovative technology, pedagogy, and curriculum. It presents clear, rigorous evidence of the impact technology can have in improving students learning of important yet complex mathematical concepts -- and goes beyond a focus on technology alone to clearly explain how teacher professional development, pedagogy, curriculum, and student participation and identity each play an essential role in transforming mathematics classrooms with technology. Further, evidence of effectiveness is complemented by insightful case studies of how key factors lead to enhancing learning, including the contributions of design research, classroom discourse, and meaningful assessment. The volume organizes over 15 years of sustained research by multiple investigators in different states and countries who together developed an approach called "SimCalc" that radically transforms how Algebra and Calculus are taught. The SimCalc program engages students around simulated motions, such as races on a soccer field, and builds understanding using visual representations such as graphs, and familiar representations such as stories to help students to develop meaning for more abstract mathematical symbols. Further, the SimCalc program leverages classroom wireless networks to increase participation by all students in doing, talking about, and reflecting on mathematics. Unlike many technology programs, SimCalc research shows the benefits of balanced attention to curriculum, pedagogy, teacher professional development, assessment and technology -- and has proven effectiveness results at the scale of hundreds of schools and classrooms. Combining the findings of multiple investigators in one accessible volume reveals the depth and breadth of the research program, and engages readers interested in: * Engaging students in deeply learning the important concepts in mathematics * Designing innovative curriculum, software, and professional development · Effective uses of technology to improve mathematics education * Creating integrated systems of teaching that transform mathematics classrooms * Scaling up new pedagogies to hundreds of schools and classrooms * Conducting research that really matters for the future of mathematics learning * Engaging students in deeply learning the important concepts in mathematics * Designing innovative curriculum, software, and professional development · Effective uses of technology to improve mathematics education * Creating integrated systems of teaching that transform mathematics classrooms * Scaling up new pedagogies to hundreds of schools and classrooms * Conducting research that really matters for the future of mathematics learning

Simple Methods to Study Pedology and Edaphology of Indian Tropical Soils

by D. K. Pal

This book discusses how research efforts have established an organic link between pedology and edaphology of five pedogenetically important soil orders as Alfisols, Mollisols, Ultisols, Vertisols and Inceptisols of tropical Indian environments. The book highlights how this new knowledge was gained when research efforts were complemented by high resolution mineralogical, micro morphological and age-control tools. This advancement in basic and fundamental knowledge on Indian tropical soils makes it possible to develop several index soil properties as simple methods to study their pedology and edaphology. More than one-third of the world’s soils are tropical soils. Thus the recent advances in developing simple and ingenuous methods to study pedology and edaphology of Indian tropical soils may also be adopted by both graduate students and young soil researchers to aid in the development of a national soil information system to enhance crop productivity and maintain soil health in the 21st century.
