Book Description
The presence - or absence - of soil organic matter (SOM) has important implications for agricultural productivity. It could also have significant implications for global climate due to its role as a source/sink of carbon. Therefore, it is important to understand the issues related to the accumulation or loss of SOM, to use what we have learned from experiments to make sound decisions about soil and crop management, and to test models and future concepts concerning SOM management. A database is included with the book, presenting tabular data for 34 sites in North America. Soil Organic Matter in Temperate Agroecosystems discusses all of these issues and more, answering such questions as:

Book Description
Recent changes in the Conservation Compliance Plans for farmers shows the need for improved information on the effective management of crop residues. Residue management requires an understanding of the crop, soil, and climate in which the farming system is located. In this volume, the strategies for effective residue management are described for each region of the country to provide a comparison of the regional differences. The chapters not only describe the knowledge in each region but also suggest some of the needed areas of research required to develop an improved understanding of the processes involved in effective residue management.

Book Description
Advances in Agronomy increased its publication frequency to three volumes per year in 1993, and will continue this trend as advances in the field dictate. Volume 53 contains four excellent reviews which cover an international spectrum of advances in the crop and soil sciences. One of the most important areas of research, sustainable agriculture, is treatedin a comprehensive article in crop rotation in the twenty-first century. Aluminum in acid soils and the factors controlling its behavior are detailed in a second article. A third long review explains the role of nutrient management on water quality, which is now a critical issue for environmental conservation. The final chapter is a definitive treatise on interparticle force effects on physical behavior of soils, which has crucial influences on plant growth and yield. - Sustainable agriculture - Acid soils - Water quality and conservation - Soil physics

Book Description
Soils comprise the largest pool of terrestrial carbon and therefore are an important component of carbon storage in the biosphere-atmosphere system. Structure and Organic Matter Storage in Agricultural Soils explores the mechanisms and processes involved in the storage and sequestration of carbon in soils. Focusing on agricultural soils - from tropical to semi-arid types - this new book provides an in-depth look at structure, aggregation, and organic matter retention in world soils. The first two sections of the book introduce readers to the basic issues and scientific concepts, including soil structure, underlying mechanisms and processes, and the importance of agroecosystems as carbon regulators. The third section provides detailed discussions of soil aggregation and organic matter storage under various climates, soil types, and soil management practices. The fourth section addresses current strategies for enhancing organic matter storage in soil, modelling techniques, and measurement methods. Throughout the book, the importance of the soil structure-organic matter storage relationship is emphasized. Anyone involved in soil science, agriculture, agronomy, plant science, or greenhouse gas and global change studies should understand this relationship. Structure and Organic Matter Storage in Agricultural Soils provides an ideal source of information not only on the soil structure-storage relationship itself, but also on key research efforts and direct applications related to the storage of organic matter in agricultural soils.

Book Description
Soil Management and Greenhouse Effect focuses on proper management of soils and its effects on global change, specifically, the greenhouse effect. It contains up-to-date information on a broad range of important soil management topics, emphasizing the critical role of soil for carbon storage. Sequestration and emission of carbon and other gases are examined in various ecosystems, in both natural and managed environments, to provide a comprehensive overview. This useful reference includes chapters that address policy issues, as well as research and development priorities. The material in this volume is valuable not only to soil scientists but to the entire environmental science community.

Book Description
Pesticides have contributed impressively to our present-day agricultural productivity, but at the same time they are at the center of serious concerns about safety, health, and the environment. Increasingly, the public wonders whether the benefits of pesticides - `the perfect red apple' - outweigh the costs of environmental pollution, human illness, and the destruction of animals and our habitat. Scientists and government officials are suspected of promoting commercial interests rather than protecting human welfare.

Book Description
Drought, a serious global issue, is being aggravated by climate change. Both pedological and agronomic droughts are a major risk factor with adverse effects on agronomic productivity, food and nutritional security, and human wellbeing. This volume in the Advances in Soil Sciences series: Considers processes, factors, and causes of pedological/agronomic droughts. Discusses effects of global warming on soil drought Describes management options to enhance drought resilience of agricultural soils Presents soil moisture management options to mitigate drought Includes information on soil health and its effects on drought Explains innovative options in measurement of soil moisture content
