This series, Advances in Soil Science, presents clear and concise reviews in all areas of soil science for everyone interested in this basic resource and man's influence on it.

This book presents the concept of interacting processes in soil science. It attempts to develop a presentation of several areas of soil science in which one must consider interaction of processes in order to further understand the complexity of the soil system.

The study of soils today has taken on increased importance because a rapidly expanding population is placing demands on the soil never before experienced.

Future volumes will include both single-topic volumes as well as volumes containing reviews of different topics of soil science, as in the case of the first ten volumes.

Soil is formed from the physical and chemical weathering of rocks-processes described historically becau'se they involve eons of time-by glaciation and by wind and water transport of soil materials, which are later deposited in deltas and loessial planes.

The key to sustaining the soil resource base is to maintain, or enhance, soil quality. Soil quality cannot be seen or measured directly from the soil alone but is inferred from soil characteristics and soil behavior under defined conditions.

In the past 10 years, there has been a resurgence in interest in soil management and conservation of the soil resource. With the dedication of the National Soil Tilth Laboratory in 1989, it was decided that one contribution the laboratory could make to agri cultural science would be to foster an exchange of information on soil management.

Advances in Soil Science was conceived in 1982 to provide a forum for leading international scientists to analyze and summarize the available scientific information on a subject, assessing its importance and ident ifying additional research needs.

Soil degradation is clearly one of the most pressing problems facing man kind. Therefore, it seemed immediately important to devote a volume to the principles and technologies for restor ing degraded soils to a productive status.

From the beginning of agriculture until about 1950, increased food production came almost entirely from expanding the cropland base. 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.

Advances in Soil Science is a review series relevant to all areas of soil science. These reviews, intended primarily for scientists, teachers, and students of soil science, also provide technical background information for many additional workers and groups interested in our natural resources and man's influence on them.

This will require increased efforts of both the developed and developing countries. Much of the technology that is so successful for crop production in the developed countries cannot be utilized directly in the developing countries.

Describes methods of assessment of soil degradation by different processes in relation to their impact on agronomic productivity and environmental quality; addresses the agronomic and economic impacts of soil degradation; and considers research and development priorities.

One of the most basic resources, perhaps the most basic of all, for meeting these needs is the soil. We must not only learn how to use the soil to furnish our immediate needs, but also ensure that the ability of the soil to sustain food production in the future is unimpaired.

Several countries that were food importers just a few years ago are food exporters today. Although the world as a whole has surplus food supplies, there are millions of people without adequate food to exist, and there are additional millions who have a bare subsistence diet at best.

This book provides current information on the world's soil resources available for food production and discusses ways to maintain or improve these resources to achieve optimal production. Chapters cover global food demand, soil degradation, fertilizer needs, nutrient budgeting and plant nutrition, disease suppressive soils, soil and climate change, soil fertility management, ecological efficiency, sustainable production systems, soil resilience, and soils and human health. The contributing authors offer innovative soil and water management options. This timely resource includes numerous illustrations, tables, and equations to aid in comprehension.

Offers data on how soil erosion affects soil, water, and air quality. Important topics include solubilization, mineralization rate, carbon transfer, and sediment deposition, as well as carbon dioxide emissions, global warming potential, and the implications of soil erosion on the global carbon cycle and carbon budget.

Written for professionals and students in agricultural fields, this book addresses current problems associated with water supplies required for agricultural purposes and food production. It focuses on innovative technologies for improving soil water availability, enhancing water use efficiency, and using productive irrigation systems. The book discusses root-zone water conservation strategies; growing varieties of crops that can tolerate droughts; and using cropping systems that enhance adaptation to changing climate, among other topics. It also presents techniques that conserve water in the root zone and discusses remote sensing techniques to assess soil water regime and predict drought on a regional scale.

This book describes the laws of sustainable soil management to enhance ecosystem services while restoring degraded soils and promoting sustainable use. With chapters contributed by world-class soil scientists, ecologists, and social scientists, the book outlines critical changes in management of agricultural soils necessary to address global issues of food security, climate change, water security, and energy needs. Topics covered include organic farming, soil fertility, crop-symbiotic soil microbiota, human-driven soil degradation, soil degradation and restoration, carbon sink capacity of soils, and soil renewal and sustainability.

Focuses on coupled processes in soil. This work covers topics including the effects of inorganic salts upon water flow, modeling of sorption, transport and transformation of organic solutes, and the effects of microorganisms on silicate clay minerals. It is suitable for researchers and students in soil science and soil and water engineering.

Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers.This book presents methods for enhancing the efficiency of fertilizer that can reduce the environmental footprint.

Bringing together international experts to explore land misuse and mismanagement practices that compromise soil quality around the globe, this volume assesses farming systems in Sub-Saharan Africa, examines land degradation and soil management in Brazil and China, and provides a comparison of systems in India and Ohio. It also addresses how cultural and spiritual beliefs may contribute to problems with soil quality. The book highlights the urgency of the issue and details achievable methods for improvement.

Soils comprise the largest pool of terrestrial carbon and therefore are an important component of carbon storage in the biosphere-atmosphere system. This book explores the mechanisms and processes involved in the storage and sequestration of carbon in soils. It emphasizes the importance of the soil structure-organic matter storage relationship.
