Download or read book Productivity Effects of Cropland Erosion in the United States written by Pierre R. Crosson and published by Routledge. This book was released on 2016-03-17 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1970’s, agriculture in the United States seemed to be booming. With an extra demand for crops, extra acres were taken on to increase production which was predicted to increase further with an ever-growing population. However, concerns were beginning to be raised over the adequacy of land for crops as potential croplands began to be converted into urban areas as well as the effects of soil erosion decreasing the quality of these croplands. Originally published in 1983, this study investigates the threats to crop productivity in the U.S. with a focus on human-made problems. This title will be of interest to students of environmental studies.

Download or read book Predicting Rainfall Erosion Losses written by Walter H. Wischmeier and published by . This book was released on 1978 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Universal Soil Loss Equation (USLE) enables planners to predict the average rate of soil erosion for each feasible alternative combination of crop system and management practices in association with a specified soil type, rainfall pattern, and topography. When these predicted losses are compared with given soil loss tolerances, they provide specific guidelines for effecting erosion control within specified limits. The equation groups the numerous interrelated physical and management parameters that influence erosion rate under six major factors whose site-specific values can be expressed numerically. A half century of erosion research in many States has supplied information from which at least approximate values of the USLE factors can be obtained for specified farm fields or other small erosion prone areas throughout the United States. Tables and charts presented in this handbook make this information readily available for field use. Significant limitations in the available data are identified.

Book excerpt: The six chapters of this book present an extensive review of soil erosion data and its effect on yield levels in the USA. One paper deals with a more theoretical approach to the relation between soil productivity and top soil depth (i.c. soil erosion) and technology. Another deals with the relation of soil erosion and developments in farming and the two final papers with policy implications
Download or read book Soil erosion the greatest challenge for sustainable soil management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-05-16 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.
Download or read book Conservation Tillage in U S Agriculture written by Noel Uri and published by CRC Press. This book was released on 2021-05-30 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Do USDA Farm Program Participants Contribute to Soil Erosion written by K. H. Reichelderfer and published by . This book was released on 1985 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extract: Only about one-third of U.S. cropland with excessive soil erosion rates is operated by farmers who might be influenced to reduce erosion if changes were made in the U.S. Department of Agriculture's commodity and soil conservation programs. The present commodity programs may conflict with conservation programs by encouraging the cultivation of erosive crops. Efforts to increase the consistency of USDA commodity and conservation programs would contribute little to overcoming the Nation's total erosion problems. Such efforts, however, should balance conservation objectives with objectives for farm income, commodity prices, production, and export.
