Tillage For Soil And Water Conservation In The Semi Arid Tropics

Chapter 3 gives a review of the various tillage systems as they may be applied for soil and water conservation, based the soil characteristics and on different mechanization levels.

The problems of agriculture in the semi-arid regions; Assessing the possibilities for improving agriculture; Soil conservation; Water conservation; Water harvesting and use; Applications of water conservation.

The objectives of this Bulletin are to collate up-to-date information on soil tillage requirements for soils in the tropics; to assess the impacts of different ways of tillage on soil, environment and crop productivity; and to outline criteria for developing environment-friendly and economically viable tillage techniques for sustainable use of soil and water resources

Conservation tillage systems have been adopted by farmers in many countries to solve the problem of land degradation and declining water productivity. Direct application of such tillage systems has not been possible among resource-poor, smallholder farmers in semi-arid areas of Ethiopia. Problems such as the lack of rainfall, the costs of herbicide

The setting; A program for resource management research; The program at ICRISAT; The international program; Summary and conclusions.

In this invaluable book, leading agronomic researchers provide in-depth reviews of present conservation tillage practices in a wide variety of temperate agroecosystems. Each chapter characterizes how conservation tillage has been developed and adapted or modified to fit specific environments, with the chapters divided into the following climate regions: Cool Humid, Cool Humid to Warm Humid, Warm Humid, and Sub-Humid to Semi-Arid Continental. Each chapter also discusses important topics such as weed problems, crop rotation, fertilizer requirements, soil properties and processes, soil erosion, soil chemistry, soil physics, and environmental issues. A perfect working reference, this resource provides a synthesis of existing research and practices and shows how soil, climatic, and biological constraints can be overcome or circumvented.

Discover farming techniques that will decrease soil erosion and costs! Soil erosion from U.S. croplands has long been recognized as a national problem. Conservation Tillage in U.S. Agriculture: Environmental, Economic, and Policy Issues is the first ever complete study of the costs and benefits of using conservation tillage to prevent soil erosion. Designed for professionals working in the areas of soil science, agronomy, economics, environmental studies, and agriculture, this complete study covers everything from machinery and trends in conservation tillage to its adoption to use in regions of the United States. With this in-depth manual, you will examine different types of tillage and the many benefits this practice can ensure, such as improving water quality, increasing organic matter in your soil, sequestering carbon, and providing habitat and food for wildlife. Covering the economic, environmental, and policy issues of this practice, Conservation Tillage in U.S. Agriculture features: the history of conservation tillage case studies on costs and benefits of differing conservation tillage practices with various crops tables and graphs of trends, and case studies concerning the use of different farming methods U.S. Department of Agriculture soil conservation policies how to prevent soil erosion without harming the environment factors affecting conservation tillage, adoption, and use for crops such as peanuts, potatoes, beets, tobacco, and vegetables. With the help of this book, you will measure the benefits and costs of conservation tillage based on profitability and environmental impact and explore the positive and negative environmental consequences that may involve air, land, water, and/or the health and ecological status of wildlife. Conservation Tillage in U.S. Agriculture is a timely and informative look at conservation tillage practices that will help you improve residue management and create better conditions for wildlife and the environment.
