Book SynopsisHow has it come to this point in our history that we hardly value the food we eat and the soil that it's grown in? How is it that we care so little how food production impacts animals and the environment?Industrial farming has transformed Britain's rural landscapes, increasing crop yields and reducing hunger. Yet this has all come at a terrible ecological cost. It is both a miracle and a disaster'.Six Inches of Soil, the film and this companion book, is the inspiring story of three British farmers standing up to the industrial food system and transforming the way they produce food to heal the soil, benefit our health and provide for local communities.Six Inches of Soil is a story of courage, vision and hope. This book is not just for farmers. Reconnecting with our food, and regenerating our soils, ourselves and our communities benefits everyone and needs everyone to be involved. We want to inspire farmers with the confidence and practical know-how to adopt regenerative farming approac

Book SynopsisGrazing management might seem simple: just put livestock in a pasture and let them eat their fill. However, as Sarah Flack explains in The Art and Science of Grazing, the pasture/livestock relationship is incredibly complex. If a farmer doesn’t pay close attention to how the animals are grazing, the resulting poorly managed grazing system can be harmful to the health of the livestock, pasture plants, and soils. Well-managed pastures can instead create healthier animals, a diverse and resilient pasture ecosystem, and other benefits. Flack delves deeply below the surface of “let the cows eat grass,” demonstrating that grazing management is a sophisticated science that requires mastery of plant and animal physiology, animal behavior, and ecology. She also shows readers that applying grazing management science on a working farm is an art form that calls on grass farmers to be careful observers, excellent planners and record-keepers, skillful interpreters of their observations, and creative troubleshooters. The Art and Science of Grazing will allow farmers to gain a solid understanding of the key principles of grazing management so they can both design and manage successful grazing systems. The book’s unique approach presents information first from the perspective of pasture plants, and then from the livestock perspective—helping farmers understand both plant and animal needs before setting up a grazing system. This book is an essential guide for ruminant farmers who want to be able to create grazing systems that meet the needs of their livestock, pasture plants, soils, and the larger ecosystem. The book discusses all the practical details that are critical for sustained success: how to set up a new system or improve existing systems; acreage calculations; paddock layout; fence and drinking water access; lanes and other grazing infrastructure; managing livestock movement and flow; soil fertility; seeding and reseeding pastures; and more. The author includes descriptions of real grazing systems working well on dairy, beef, goat, and sheep farms in different regions of North America. The book covers pasture requirements specific to organic farming, but will be of use to both organic and non-organic farms.Trade ReviewCHOICE- "This is a great book. After reading this work, the reviewer felt as if he could almost start his own grazing system; the title provides readers with the right questions to ask. Flack (a consultant on grazing and organic livestock) is a concise and articulate author and educator. She knows the value of telling a simple story and supporting it with relevant illustrations. She has an elegant style and knows how to use the power of repetition to show how no part of grazing management is wholly independent. She has biases with respect to the best grazing management, but is evenhanded in presenting multiple alternatives to grazing issues. Her case studies are aptly chosen to illustrate how the grazing management she advocates can be both sustainable and profitable. Each chapter plays a role and successively builds on the knowledge previously gained. As a manual for introducing good land stewardship, this book admirably succeeds. Summing Up: Highly recommended. All readers.”“I have long been fascinated by the logic of André Voisin’s system of Rational Grazing. Sarah Flack’s book has persuaded me that this could be a practical option for my own micro-dairy holding.”--Simon Fairlie, author of Meat“It gives me pleasure to recommend Sarah Flack’s The Art and Science of Grazing. Sarah offers sound practical information for management of pastures in humid environments. Her years of experience and study allow her to explain the limitations of rotational grazing that were first highlighted by Andre Voisin and to confirm the soundness of Voisin’s Rational Grazing.”--Allan Savory, president, Savory Institute“With feet firmly planted in both practice and science, Sarah Flack introduces pasture-based livestock production in a way that is sure to encourage and empower.”--Joel Salatin, author of Salad Bar Beef“The Art and Science of Grazing is a beautiful and highly useful book. Read it, learn how to manage pasture well, then do it! Sarah Flack’s good counsel can save your farm and family and bring you happiness. What else is there?”--Bill Murphy, author of Greener Pastures on Your Side of the Fence“Amidst the flood of information on modern grass farming, Sarah Flack performs nothing short of a rescue operation, distilling the art and science of grazing into an immensely useful book. Experienced hands will learn plenty, but newcomers won’t be overwhelmed. The Art and Science of Grazing is sure to become one of the most well-worn books on graziers’ bookshelves.”--Fred Walters, publisher, Acres U.S.A.“Sarah Flack has written a wonderful guide to sustainable grazing. She discusses fundamental principles and specific practices that make her book meaningful for anyone interested in the art and science of grazing.”--Fred Provenza, professor emeritus, Department of Wildland Resources, Utah State University “More and more farmers and ranchers are thirsting for information on animal husbandry that truly protects and regenerates natural resources while enhancing economic viability. Sarah Flack is answering the call. In a readable, user-friendly format, her book provides concrete information and plenty of inspiration. An invaluable resource for anyone raising grazing animals.”--Nicolette Niman, author of Defending Beef“Sarah Flack’s The Art and Science of Grazing is an excellent guide for anyone with an interest in the regenerative potential of livestock grazing done right. Whether you are a farmer, rancher, conscientious consumer of meat, or concerned citizen of the planet, Flack’s clear, concise prose explains how good grazing is a natural fit in our world.”--Courtney White, author of Two Percent Solutions for the Planet“Intelligently managed grazing has tremendous potential to mitigate climate turmoil, and The Art and Science of Grazing contains everything you need to know to do the very best job of grazing. Sarah Flack explores every aspect of holistic pasture management in a most delightful manner that will help all who consult her book, from beginners to the most experienced graziers, to achieve their maximum potential in healing the Earth with livestock and land.”--Jack Lazor, author of The Organic Grain Grower“The Art and Science of Grazing is a comprehensive guide for new and experienced graziers. If I had to choose one book as a reference on grazing for both new and experienced livestock graziers, this would be it. The book is well organized, containing many excellent illustrations and beautiful photographs. Sarah Flack shares her knowledge on all aspects of grazing with emphasis on key principles that apply to all farms in humid regions. Multiple case studies provide interest and wisdom gained by farmers who have developed diverse, successful grazing operations throughout the country.”--Guy Jodarski, DVM, CROPP Cooperative/Organic Valley

Book SynopsisThis book is unique in providing a comprehensive, up-to-date synthesis of what is known about soil biodiversity and the factors that regulate its distribution, as well as the functional significance of below-ground biodiversity for ecosystem form and function. It describes the vast diversity of biota that live in the soil environment - the most complex habitat on Earth - and discusses the factors that act as determinants of this diversity across different spatial and temporal scales. The Biology of Soil also considers how biotic interactions in soil influence the important soil processes of decomposition and nutrient cycling . It demonstrates how interactions and feedbacks between diverse plant and soil communities act as important drivers of ecosystem form and function. The importance of these relationships for understanding how ecosystems respond to global change phenomena, including climate change, is discussed in depth. Much is still to be learned about the soil biota and their rolTrade ReviewI recommend this book to soil ecologists across a range of expertise and to soil and environmental scientists who want to increase their understanding of the role of soil biota in ecosystem processes. * European Journal of Science, 58, 1213-1220 *Our understanding of how soils function is rapidly growing and this small, easily read book will bring everyone up to date, backed up by an impressive bibliography...as an introductory text it is excellent. Peter Thomas, Bulletin of the British Ecological Society 2006, 37:2... this book has immense potential as a core key teaching resource for instructing ecology students about the importance of soils and aboveground-belowground feedbacks. In addition to recommending this as a teaching text, I strongly recommend The Biology of Soil to any ecologist who does not actively work in soils and wants to learn more about their fascinating ecology. * Trends in Ecology and Evolution and Evolution *Table of ContentsPreface and acknowledgements ; 1.

Book SynopsisFor much of history, soil has played a major, and often central, role in the lives of humans. Entire societies have risen, and collapsed, through the management or mismanagement of soil; farmers and gardeners worldwide nurture their soil to provide their plants with water, nutrients, and protection from pests and diseases; major battles have been aborted or stalled by the condition of soil; murder trials have been solved with evidence from the soil; and, for most of us, our ultimate fate is the soil. In this book Richard Bardgett discusses soil and the many, and sometimes surprising, ways that humanity has depended on it throughout history, and still does today. Analysing the role soil plays in our own lives, despite increasing urbanization, and in the biogeochemical cycles that allow the planet to function effectively, Bardgett considers how superior soil management could combat global issues such as climate change, food shortages, and the extinction of species. Looking to the future, Bardgett argues that it is vital for the future of humanity for governments worldwide to halt soil degradation, and to put in place policies for the future sustainable management of soils.Trade Reviewhighly readable and authoritative book * Network Review *Richard Bardgett is one of the most eloquent and knowledgeable of the soil scientists who have cotnributed to the current enthusiasm about soils ... a must read * Wim H. van der Putten, Trends in Ecology & Evolution *In conclusion this is an excellent, concise and very well written text which should be read by as wide a readership as possible, not just Soil Scientists.

Book SynopsisAcross the world, the risks of wildfires are increasing and expanding. Due to past and current human actions, we dwell in the age of fire the Pyrocene and the many challenges and climate adaptation questions it provokes. Exploring our past and current relationships with fire, this book speculates on the pyro futures yet to be designed and cared for.Drawing upon fieldwork, mapping, drone imagery, and interviews, this publication curates 27 global design case studies within the vulnerable and dynamic wildland-urban interface and its adjacent wildlands. The book catalogs these examples into three approaches: those that resist the creative and transformative power of fire and forces of landscape change, those that embrace and utilize those forces, and those that intentionally try to retreat and minimize human intervention in fire-prone landscapes. Rather than serving as a book of neatly packaged solutions, it is a book of techniques to be considered, tested, and evaluated in a Trade Review"It’s no longer enough to live with fire. We have to live with a fire age. That requires new thinking, novel classifications, fresh metaphors and models, a vision of what can happen where fire, town, and country converge, so it’s great to see what landscape architects have to say. Design by Fire is a welcome contribution to an urgent problem." Stephen Pyne, ASU, author of The Pyrocene"Design by Fire is the essential guidebook and atlas for the pyro-future that is already here. Whether homeowner, concerned citizen, designer, or policymaker, you will find in these extraordinarily researched and illustrated pages a foundation for understanding – and living in – the world to come." Alexander Robinson, USC School of Architecture, author of The Spoils of Dust: Reinventing the Lake that Made Los Angeles"Design by Fire is a necessary book for all landscape architects and planners. The insightful interviews, succinct strategies, and emphasis on co-creative approaches structure the book, while the authors challenge us to grapple with current practices. They help us imagine a future in which reparations can bring traditional ecological knowledge to the forefront and imbue us with a culture of stewardship."

Book SynopsisDevelopments in the modelling of sediment transport in rivers and the interactions with the river-bed have been remarkable over the last two decades. This progress has increased the understanding of the nature of turbulence, and the ability to replicate mathematically simple flow-particle interactions which can be observed experimentally. In addition, quite elegant models of stratigraphic complexes have evolved because of the growing computational power available to scientists. As always, additional knowledge has raised even more intriguing questions and the quest for explanation of phenomena has led to increased specialisation. Therefore, there are few fluid dynamicists or sedimentologists who can successfully span the two disciplines. The intention of this book is to assist various specialists on keeping abreast of current developments in related areas. The book initially focuses on hydrodynamics of turbulent flow, followed by basic two and three-dimensional flow through straight andTable of ContentsPartial table of contents: Turbulent Flow in Rivers (J.

Book SynopsisAcid deposition is considered to be one of the greatest threats to the environment in industrialised countries. Recognising this , governments have instituted programmes to reduce emissions of SO2, and NOx, the major sources of acid rain. But is this enough? Will ecosystems damaged by acid rain recover? And if they do, how quickly? What ecosystem processes determine the rate of recovery? Do acidification models give accurate predictions? Are any other actions necessary to promote recovery? To answer such questions without waiting for the results of current policies, scientists in Sweden and the UK decided to eliminate acid deposition on an acidified ecosystem altogether, and monitor the effects. They did this by constructing a huge roof over an acidified catchment near Lake G?rdsjon in Southwest Sweden. Acid rain falling on the roof is diverted away, and replaced with clean rain. The detailed responses of the ecosystem are measured.

Book SynopsisThe discipline of Stochastic Processes is usually treated as a branch of mathematics, and there are plenty of books for mathematicians on the subject. Equally, there are very many books, both for statisticians and environmental scientists, on Time Series Analysis, analysing the structure of data sequences where measurements are made at equal time-intervals and are free from intermittent behaviour. But this book deals with the analysis of events which occur intermittently in time and space; through a very wide range of examples drawn from many areas of environmental science in which the role of water is central, the book shows how the same analytical procedures can be applied to very many different problems. The book s many examples include: analysis of time intervals between el Ni?o events, frequency of dry spells, the relation between heavy rainfall and flooding, occurrences of gravel disturbance in upland trout streams which damages trout spawn deposits and the cellular structure of Table of ContentsModels: Deterministic, Time Series and Stochastic.

Book SynopsisEstuaries is a comprehensive introductory text emphasizing the physical processes involved in the mixing of sea and river water and the transport of fine sediments within the complex estuarine topographic context. The theoretical and mathematical formulation of these processes are treated at a fairly elementary level, and are used to develop a foundation for more extensive study. The second edition retains the classical approaches to the tidally averaged circulation and mixing conditions but broadens them to consider recent advances in the understanding of processes occurring within the tide. The scope has also been widened to include more detail on the morphology of estuaries and their development, the fluxes of suspended fine sediments, and the generation and maintenance of turbidity maximum. The book provides an excellent introduction for research students in oceanography, environmental science, geography, geology, and water and coastal engineering.

Book SynopsisThis textbook is aimed at the majority of students, who need to quickly acquire a concise overview of soil science. Many current soil science textbooks still cater for a traditional student market where students embark on three years study in a narrow discipline. The growth in modular degree schemes has meant that soil science is now often taught as self-standing unit as part of broad based degree program. Students pursuing this type of course are increasingly reluctant to purchase expensive textbooks that are too detailed and often assume a scientific background. For those opting to specialise in soil science there are a variety of good textbooks to choose from. This short informative guide, will be particularly useful for students who do not possess a traditional scientific background, such as those studying geography, environment science, ecology and agriculture. Only textbook to cater for introductory courses in soil science.<Trade Review"...It is rare that texts are found combining ease of understanding with a solid scientific foundation. The subtitle of this text 'a clear and concise introduction to soil science' does indeed sum up this book.

Book SynopsisWhile organic soils have the potential to contribute greatly to agricultural production, the irreversible processes that occur from draining organic soils need to be managed with caution. The wise use of peatlands must include the avoidance of unacceptable ecological effects on the contiguous and global environment. Organic Soils and Peat Materials for Sustainable Agriculture provides detailed information from a worldwide perspective on the degradation process of fragile peat resources used for agriculture. It documents the best management practices and defines and quantifies soil quality indicators and pedo-transfer functions for organic soils and peat materials.Co-published with the International Peat Society, this reference is the first to integrate the physical, chemical, and biological aspects of organic soils and peat materials for sustainable agriculture and horticulture. It details the principles and indicators behind positive action in sustainable management. The book presents a complete analysis of how peat works chemically, physically, and ecologically. It quantifies the moorsh-forming, or peat degradation, process in tables and figures, provides conversion equations among pH determination methods, and supplies a novel diagnosis of N and P release. In addition, the book revisits water, pesticides, phosphorus, and copper sorption characteristics of organic soils.The authors provide up-to-date information in order to define quality indicators for the optimum use of organic soils. With detailed information and a global perspective, Organic Soils and Peat Materials for Sustainable Agriculture aims to promote a shift from the current paradigm of input-based unsustainable use to a new knowledge-based approach.Table of ContentsThe Moorsh or Muck Horizons as Quality Indicators of Reclaimed Organic Soils.

Book SynopsisI've seen the Sudan, traveled in South and Central America and been all over Europe, but I've never seen what I've been able to see on this tour [of the Loess Plateau, China].-Ed Skidmore, soil scientist, WindErosion Research Unit of the Agricultural Research Service, USDA, Manhattan, KansasOverpopulation is at the core of most environmental problems. The impacts of continued growth-with world population reaching 6 billion in October 1999-are felt in most parts of the world. China, the most populous nation, illustrates many of the pivotal problems-and solutions.Although China faces the same effects of overpopulation as the rest of the world, it still feeds over a billion people on a tillable area that allows about one tenth of a hectare per person. The country's efforts to tie together soil and water conservation, dryland farming, and economic development have been largely successful. Soil Erosion and Dryland Farming explores these trials and the lessons learned Trade Review"Soil Erosion and Dryland Farming presents these techniques and technologies to give you a forward looking perspective into the field, as well as the larger problem of tailoring food production to sustain the population."--Vol. 32 NO. 1- 2001; Agricultural Mechanization in Asia, Africa and Latin AmericaTable of ContentsSection I: Dryland Farming Systems and Soil Water Management.

Book SynopsisThis book provides a comprehensive overview of grassland nitrogen incorporating information from crop science, soils and fertilizers, ruminant consumption and environmental aspects. The published information is reviewed on the various transformations of nitrogen in temperate grassland systems. These include those taking place in soils. The effects of soil, weather and management practices are discussed and considerable emphasis is placed on soil-plant-animal interactions. A second aim of the book is to describe the factors that influence the response of grassland to the application of fertilizer nitrogen, and how the optimum rate of application may be determined. In addition, nitrogen balances are described for different grassland systems, showing how the annual inputs and outputs vary greatly depending on sward type and management. The book is of interest to a wide readership, especially those engaged in research, teaching and advisory work, and students taking courses in agriculturalTable of Contents1: Grasses: uptake of nitrogen and effects on morphology and physiology 2: Legumes: biological nitrogen fixation and interaction with grasses 3: Consumption, digestion and excretion of nitrogen by ruminant livestock 4: Amounts, sources and fractionation of organic nitrogen in soils 5: Mineralization, immobilization and availability of nitrogen in soils 6: Leaching of nitrogen from soils 7: Volatilization of ammonia 8: Volatilization of gaseous nitrogen and nitrogen oxides through denitrification and nitrification 9: Use of fertilizer nitrogen and slurry nitrogen on grasslands: recovery and response 10: Response to fertilizer nitrogen: influence of sward type, pattern of fertilizer application and method of harvesting 11: Response to fertilizer nitrogen: influence of weather, seasonal factors and soil type 12: Response to fertilizer nitrogen: influence of type of fertilizer and supplies of other nutrients 13: Influence of fertilizer nitrogen on the composition and nutritional quality of grassland herbage 14: Nitrogen balances in contrasting grassland systems
