Understanding Roots uncovers one of the greatest mysteries underground—the secret lives and magical workings of the roots that move and grow invisibly beneath our feet. Roots, it seems, do more than just keep a plant from falling over: they gather water and nutrients, exude wondrous elixirs to create good soil, make friends with microbes and fungi, communicate with other roots, and adapt themselves to all manner of soils, winds, and climates, nourishing and sustaining our gardens, lawns, and woodlands. Understanding Roots contains over 115 enchanting and revealing root drawings that most people have never seen, from prairies, grasslands, and deserts, as well as drawings based on excavations of vegetable, fruit, nut, and ornamental tree roots. Every root system presented in this book was drawn by people literally working in the trenches, sketching the roots where they grew. The text provides a verydetailed review of all aspects of transplanting; describes how roots work their magic to improve soil nutrients; investigates the hidden life of soil microbes and their mysterious relationship to roots; explores the question of whether deep roots really gather more unique nutrients than shallow roots; shares the latest research about the mysteries of mycorrhizal (good fungal) association; shows you exactly where to put your fertilizer, compost, water, and mulch to help plants flourish; tells you why gray water increases crop yields more than fresh water; and, most importantly, reveals the science behind all the above (with citations for each scientific paper). This book contains at least eighty percent more new information, more results of the latest in-depth and up-to-date explorations, and even more helpful guidelines on roots than the author’s previous book (Roots Demystified: Change Your Garden Habits to Help Roots Thrive). This is not a revised edition—it’s a whole new stand-alone book.

New and Improved Global Edition: Three-Volume Set A ready reference addressing a multitude of soil and soil management concerns, the highly anticipated and widely expanded third edition of Encyclopedia of Soil Science now spans three volumes and covers ground on a global scale. A definitive guide designed for both coursework and self-study, this latest version describes every branch of soil science and delves into trans-disciplinary issues that focus on inter-connectivity or the nexus approach. For Soil Scientists, Crop Scientists, Plant Scientists and More A host of contributors from around the world weigh in on underlying themes relevant to natural and agricultural ecosystems. Factoring in a rapidly changing climate and a vastly growing population, they sound off on topics that include soil degradation, climate change, soil carbon sequestration, food and nutritional security, hidden hunger, water quality, non-point source pollution, micronutrients, and elemental transformations. New in the Third Edition: Contains over 600 entries Offers global geographical and thematic coverage Entries peer reviewed by subject experts Addresses current issues of global significance Encyclopedia of Soil Science, Third Edition: Three Volume Set expertly explains the science of soil and describes the material in terms that are easily accessible to researchers, students, academicians, policy makers, and laymen alike. Also Available Online This Taylor & Francis encyclopedia is also available through online subscription, offering a variety of extra benefits for researchers, students, and librarians, including: Citation tracking and alerts Active reference linking Saved searches and marked lists HTML and PDF format options Contact Taylor and Francis for more information or to inquire about subscription options and print/online combination packages.

Soil acidity is a major limitation to crop production in many parts of the world. Plant growth inhibition results from a combination of factors, including aluminum, manganese, and hydrogen ion toxicities and deficiencies of essential elements, particularly calcium, magnesium, phosphorus, and molybdenum. Agricultural management practices and acid precipitation have increased acid inputs into the ecosystem and heightened concern about soil acidity problems. While application of lime has proved to be effective in ameliorating surface soil acidity in many areas, significant soil acidity problems still exist. Scientists from Alberta, Canada, recognized the need to provide a forum for researchers from different disciplines to exchange information and ideas on solving problems of plant growth in acid soils. As a result of their efforts, the First International Symposium on Plant-Soil Interactions at Low pH was held at Grande Prairie, Alberta, Canada, in July 1987. In many acid soil areas, liming materials are not readily available, the cost may be prohibitive, or subsoil acidity cannot be corrected by surface application of lime. New management approaches involving both the plant and the soil are needed in these situations. Progress has been made in the selection and breeding of acid-tolerant plants. However, continued progress will be limited by our lack of understanding of the physiological and biochemical basis of differential acidity tolerance among plants.

"An extremely useful and much needed survey. Over eleven chapters, authors from eight countries cover the complex history of migration from the perspective of Central and Eastern Europe between 1945 and 1993. Following in the footsteps of Klaus Bade’s Encyclopedia of European Migrations, the authors make extensive use of sources in national languages, while providing an extensive overview of population movements in the region between the Baltic, Black, and Adriatic Seas. The individual chapters shed light on phenomena overlooked in other volumes, including individual state reactions to various migratory phenomenon, and the political, economic, and ideological consequences of human movement. The chapters of this volume are uniform not only in their informative nature, but also in suggesting new pathways for in-depth research." Adam Walaszek, Jagiellonian University, Kraków, Poland "Eastern Europe is an emblematic space of mobility and its Cold War history cannot be told without considering migration from and into the countries of the region. This volume comes at a timely moment and provides a uniquely comprehensive account, full with useful information for further research. It will be a must-read both for migration studies scholars and for area specialists." Ulf Brunnbauer, Leibniz Institute for East and Southeast European Studies, Regensburg, Germany "The Handbook is a gift to students of migration on three counts. It gathers the expertise of scholars fluent in the languages – and familiar with the archives – of Eastern and Central Europe. Thus it brings the multi-layered and complex histories of movement beyond the flat descriptor of "Soviet bloc" or Eastern European migrations. The Handbook is both rich and lucid, presenting in-depth materials on the European twentieth-century, on one hand, and organizing each chapter in a similar way, offering the reader transparently comparable histories. From Estonia south to Albania, and from the USSR west to the GDR, each chapter elucidates a complex migration history distinguished by national politics, ethnic composition, and economics – moving from the cataclysmic impacts of World War II to the international migrations and politics of Cold War movement, as well as the politics of Cold War emigrants themselves. Each chapter ends with an epilogue on post-1989 international migrations and a valuable addendum on published and archival sources. Finally, the Handbook models the kind of high quality work produced by international scholarly cooperation at its best."
