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

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.

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

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.

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.

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.

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.

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.

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 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.

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.

This study addresses the importance of soil processes in the global carbon cycle, and on the mechanisms that influence carbon cycling in the soil-plant-atmosphere continuum. Topics covered include: soil carbon dynamics and processes; modelling SOC; and methods of SOC determinations.

Presents a review of soil properties and processes negatively impacted by crop residue removal. This title outlines the ecological consequences of biofuels and evaluates land use in the production of raw material for biofuel.

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.

The UN Millennium Development Goals' intent to halve hunger by 2015 will not be realized. This title presents an exploration of the problem at hand and the critical steps needed to reverse it. It examines concerns with and approaches to soil quality management in Brazil and China.
