Soil Science and Management, fifth edition, emphasizes the human interaction with and effect on soils, rather than treating the soil as an independent element. Non-technical and easy-to-understand, Soil Science and Management, fifth edition teaches the essentials of soils from the perspective of farmers, horticulturalists, environmentalists and other who are concerned about how soils work and how they are used more effectively. An emphasis on management and the sustainable use of soil and water resources makes it especially relevant to these audiences. The inclusion of nutrient management, best practices and relevant legal issues and government programs make this text a practical application for students.

Just five years ago, it was generally believed that the number of food insecure people in the world was on continuous decline. Unfortunately, widespread soil degradation along with resistance to recommended agronomic practices, and little attempt to restore degraded soils have conspired with significant droughts (in regions that could least tolerate them) to swell the ranks of the food insecure to over a billion people. The U.N. Millennium Development Goals’ intent to halve hunger by 2015 will not be realized. Food Security and Soil Quality brings together leading experts from across the world to provide a concise and factually supported exploration of the problem at hand and the critical steps needed to reverse it. Edited by Rattan Lal, and B.A. Stewart, two of the world’s most respected soil scientists, this important work — Assesses farming systems and food security in Sub-Saharan Africa, with special emphasis on land degradation Examines concerns with and approaches to soil quality management in Brazil and China Details achievable methods for improving soil quality for sustainable production Provides an insightful comparison of temporal changes in agricultural systems productivity in Punjab, India and Ohio Discusses the human dimension of the crisis including the influence of culture and spiritual beliefs Dr. Lal himself writes that despite the existence of scientific data on sustainable management of soil and water resources, problems of soil and environmental degradation have persisted and have been aggravated. And that these problems are rooted in land misuse and soil mismanagement. This book does provide policymakers and others with an understanding of the depth, complexity, and immediacy of this crisis, but more than a call to action, it also offers soil scientists working in this area with an understanding of what is being done and what needs to be done. Most importantly, this book helps us understand that the situation is not beyond remediation were we to act with great resolve and a sense of urgency. A tree's leaves may be ever so good, So may its bark, so may its wood; But unless you put the right thing to its root, It never will show much flower or fruit. — from Leaves Compared With Flowers, by Robert Frost

The organization of topics, the depth and breadth of coverage and the incorporation of applied material throughout the book are all aimed at helping students learn. This approach for both majors and non-majors is more successful than a hierarchical organization: molecules, cells, tissues, organisms and ecology. The number and titles of the chapters in the book reflect its depth and breadth. Fundamentals of Plant Science contains 22 chapters ranging from the importance of plants to plants and ecology, to biomes, to reproduction, to energy conversions, to plant, soil and water, to genetics and biotechnology, to traditional crops, to ornamentals, to wood, to fruits and nuts, to pastures and grasses. Fundamentals of Plant Science helps every student develop an understanding of how plants, impact, grow, reproduce, and function. This understanding promotes informed decision making concerning the role of plants in a functional world.

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.

From the beginning of agriculture until about 1950, increased food production came almost entirely from expanding the cropland base. Since 1950, however, the yield per unit of land area for major crops has increased dramatically. Much of the increase in yields was because of increased inputs of energy. Between 1950 and 1985, the farm tractor fleet quadrupled, world irrigated area tripled, and use of fertilizer increased ninefold. Between 1950 and 1985, the total energy used in world agriculture increased 6. 9 times. Irrigation played a particularly important role in the rapid increase in food production between 1950 and 1985. The world's irrigated land in 1950 totaled 94 million hectares but increased to 140 million by 1960, to 198 million by 1970, and to 271 million hectares in 1985. However, the current rate of expansion has slowed to less than 1 % per year. The world population continues to increase and agricultural production by the year 2000 will have to be 50 to 60% greater than in 1980 to meet demands. This continued demand for food and fiber, coupled with the sharp decline in the growth rate of irrigation development, means that much of the additional agricultural production in future years must come from cultivated land that is not irrigated. Agricultural production will be expanded in the arid and semiarid regions because these regions make up vast areas in developing countries where populations are rapidly rising.

An evolving, living organic/inorganic covering, soil is in dynamic equilibrium with the atmosphere above, the biosphere within, and the geology below. It acts as an anchor for roots, a purveyor of water and nutrients, a residence for a vast community of microorganisms and animals, a sanitizer of the environment, and a source of raw materials for construction and manufacturing. To develop lasting solutions to the challenges of balanced use and stewardship of the Earth, we require a fundamental understanding of soil—from its elastic, porous three-phase system to its components, processes, and reactions. Handbook of Soil Sciences: Properties and Processes, Second Edition is the first of two volumes that form a comprehensive reference on the discipline of soil science. Completely revised and updated to reflect the current state of knowledge, this volume covers the traditional areas of soil science: soil physics, soil chemistry, soil mineralogy, soil biology and biochemistry, and pedology. Contributors discuss the application of physical principles to characterize the soil system and mass and energy transport processes within the critical zone. They present significant advances in soil chemistry; describe how minerals are formed and transformed; and provide an introduction to the soil biota. They also examine geomorphology, land use, hydropedology, and subaqueous soils as well as the classification and digital mapping of soil. Critical elements addressed in each section include: Descriptions of concepts and theories Definitions, approaches, methodologies, and procedures Data in tabular and figure format Extensive references This cohesive handbook provides a thorough understanding of soil science principles and practices based on a rigorous, complete, and up-to-date treatment of the subject matter compiled by leading scientists. It is a resource rich in data, offering professional soil scientists, agronomists, engineers, ecologists, biologists, naturalists, and students their first point of entry into a particular aspect of the soil sciences.
