Download and read online Life in the Soil in PDF and EPUB Leonardo da Vinci once mused that “we know more about the movement of celestial bodies than about the soil underfoot,” an observation that is as apt today as it was five hundred years ago. The biological world under our toes is often unexplored and unappreciated, yet it teems with life. In one square meter of earth, there lives trillions of bacteria, millions of nematodes, hundreds of thousands of mites, thousands of insects and worms, and hundreds of snails and slugs. But because of their location and size, many of these creatures are as unfamiliar and bizarre to us as anything found at the bottom of the ocean. Lavishly illustrated with nearly three hundred color illustrations and masterfully-rendered black and white drawings throughout, Life in the Soil invites naturalists and gardeners alike to dig in and discover the diverse community of creatures living in the dirt below us. Biologist and acclaimed natural history artist James B. Nardibegins with an introduction to soil ecosystems, revealing the unseen labors of underground organisms maintaining the rich fertility of the earth as they recycle nutrients between the living and mineral worlds. He then introduces readers to a dazzling array of creatures: wolf spiders with glowing red eyes, snails with 120 rows of teeth, and 10,000-year-old fungi, among others. Organized by taxon, Life in the Soil covers everything from slime molds and roundworms to woodlice and dung beetles, as well as vertebrates from salamanders to shrews. The book ultimately explores the crucial role of soil ecosystems in conserving the worlds above and below ground. A unique and illustrative introduction to the many unheralded creatures that inhabit our soils and shape our environment aboveground, Life in the Soil will inform and enrich the naturalist in all of us.
Download and read online Soil in the Environment in PDF and EPUB Soil in the Environment is key for every course in soil science, earth science, and environmental disciplines. This textbook engages students to critically look at soil as the central link in the function and creation of the terrestrial environment. For the first time, Dr. Hillel brilliantly discusses soils as a natural body that is engaged in dynamic interaction with the atmosphere above and the strata below that influences the planet's climate and hydrological cycle, and serves as the primary habitat for a versatile community of living organisms. The book offers a larger perspective of soil’s impact on the environment by organizing chapters among three main processes: Physical, Chemical, and Biology. It is organized in a student-friendly format with examples, discussion boxes, and key definitions in every chapter. The book provides students of geology, physical science, and environmental studies with fundamental information and tools for meeting the natural resource challenges of the 21st century, while providing students of soil science and ecology with the understanding of physical and biological interactions necessary for sustainability. First textbook to unite soil science and the environment beyond what is traditionally taught Incorporates current knowledge of such hot topics as climate change, pollution control, human expropriation of natural resources, and the prospects for harmonious and sustainable development Organized in a student-friendly format with examples, discussion boxes, and key definitions in every chapter Full color throughout

Download and read online International Law and Agroecological Husbandry in PDF and EPUB Remarkable advances are being made in life science and agricultural research to reform the methods of food production, particularly with regard to staple grain and legume crops, in ways that will better reflect ecological realities. However, advances in science may be insufficient to ensure that these possibilities for agricultural reform are realized in practice and in a sustainable way. This book shows how these can only be achieved through changes in legal norms and institutions at the global level. Interdisciplinary in character, the book draws from a range of issues involving agricultural innovation, international legal history and principles, treaty commitments, global institutions, and environmental challenges, such as climate change, to propose broad legal changes for transforming global agriculture. It first shows how modern extractive agriculture is unsustainable on economic, environmental, and social grounds. It then examines the potential for natural-systems agriculture (especially perennial-polyculture systems) for overcoming the deficiencies of modern extractive agriculture, especially to offset climate change. Finally it analyses closely the legal innovations that can be adopted at national and international levels to facilitate a transition from modern extractive agriculture to a system based more on ecological principles. In particular the author argues for the creation of a Global Convention on Agroecology.
Download and read online Footprints in the Soil in PDF and EPUB The history of science discipline is contributing valuable knowledge of the culture of soil understanding, of the conditions in society that fostered the ideas, and of why they developed in certain ways. This book is about the progressive “footprints made by scientists in the soil. It contains chapters chosen from important topics in the development of soil science, and tells the story of the people and the exciting ideas that contributed to our present understanding of soils. Initiated by discussions within the Soil Science Society of America and the International Union of Soil Sciences, this book uniquely illustrates the significance of soils to our society. It is planned for soils students, for various scientific disciplines, and for members of the public who show an increasing interest in soil. This book allows us to answer the questions: “How do we know what we know about soils? and “How did one step or idea lead to the next one? The chapters are written by an international group of authors, each with special interests, bound together by the central theme of soils and how we came to our present understanding of soils. Each concentrate on soil knowledge in the western world and draw primarily on written accounts available in English and European languages. Academics, graduate students, researchers and practitioners will gain new insights from these studies of how ideas in soil science and understanding of uses of soils developed. * Discusses tracing soils knowledge accumulated from Roman times, first by soil users and after 1800s by scientists * Offers ideas about how soils knowledge was influenced by the social context and by human needs * Combines the history of ideas with scientific knowledge of soils * Written by chapter authors who combine subject matter expertise with knowledge of practical soil uses, and provide numerous references for further study of the relevant literature
Download and read online Managing for Healthy Soils in PDF and EPUB We are told that in a teaspoon of soil there may be more organisms than the total number of people on the planet. Who is conducting the count? And what does it mean? To be brutal about it: So what? We now know that just as biodiversity and balance is important in our agricultural and natural systems and landscapes to keep them healthy and robust, the same processes are vital for our soils. There’s a lot going on down there that deserves a closer look. And even if we can’t see it, a healthy, living soil will grow better plants, be more resilient and improve our agricultural productivity. So this book is designed to for a twin purpose: · to make up for the mechanistic approach of 40 years ago—to present a clearer picture of what remained a secret to the uninitiated for so long—to reveal the living, pulsing, teeming world beneath our feet, and · to help manage our soil resource by understanding that any actions we take will have an impact on soil health. Managing for Healthy Soils is a must for any farmer, horticulturalist or home gardener. It explains how to class your type of soil, understand the limitations and potential, and manage it sustainably. Soil tests for moisture, water infiltration, pH, soil nutrients, soil texture, soil compaction, structural stability and more will help you understand your soil context. CONTENTS Preface Chapter 1.

Download and read online Soil and Plant Analysis for Forest Ecosystem Characterization in PDF and EPUB This handbook provides and overview of physical, chemical and biological methods used to analyze soils and plant tissue using an ecosystem perspective. The current emphasis on climate change has recognized the importance of including soil carbon as part of our carbon budgets. Methods to assess soils must be ecosystem based if they are to have utility for policy makers and managers wanting to change soil carbon and nutrient pools. Most of the texts on soil analyis treat agriculture and not forest soils and these methods do not transfer readily to forests because of their different chemistry and physical properties. This manual presents methods for soil and plant analysis with the ecosystem level approach that will reduce the risk that poor management decisions will be made in forests.

Download and read online Principles of Sustainable Soil Management in Agroecosystems in PDF and EPUB With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be doubled or tripled through adoption of technologies based on laws of sustainable soil management. Principles of Sustainable Soil Management in Agroecosystems describes the application of these laws to enhance ecosystem services while restoring degraded soils and promoting sustainable use. With chapters contributed by world-class soil scientists, ecologists, and social scientists, this book outlines critical changes in management of agricultural soils necessary to achieve food security and meet the food demands of the present and projected future population. These changes include conversion to no-till and conservation agriculture; adoption of strategies of integrated nutrient management, water harvesting, and use of drip sub-irrigation; complex cropping/farming systems such as cover cropping and agroforestry; and use of nano-enhanced fertilizers. The book is based on the premise that it is not possible to extract more from a soil than what is put into it without degrading its quality. The strategy is to replace what is removed, respond wisely to what is changed, and be pro-active to what may happen because of natural and anthropogenic perturbations. The chapters, which exemplify these ideas, cover a range of topics including organic farming, soil fertility, crop-symbiotic soil microbiota, human-driven soil degradation, soil degradation and restoration, carbon sink capacity of soils, soil renewal and sustainability, and the marginality principle.

Download and read online The Sacred Balance in PDF and EPUB In this extensively revised and enlarged edition of his best-selling book, David Suzuki reflects on the increasingly radical changes in nature and science — from global warming to the science behind mother/baby interactions — and examines what they mean for humankind’s place in the world. The book begins by presenting the concept of people as creatures of the Earth who depend on its gifts of air, water, soil, and sun energy. The author explains how people are genetically programmed to crave the company of other species, and how people suffer enormously when they fail to live in harmony with them. Suzuki analyzes those deep spiritual needs, rooted in nature, that are a crucial component of a loving world. Drawing on his own experiences and those of others who have put their beliefs into action, The Sacred Balance is a powerful, passionate book with concrete suggestions for creating an ecologically sustainable, satisfying, and fair future by rediscovering and addressing humanity’s basic needs.
