Wind Erosion and Its Control


Book Description




Physics and Modelling of Wind Erosion


Book Description

This book provides a comprehensive summary of the recent developments in wind-erosion research and a clear outline of its future directions. The physics of wind-erosion, from particle entrainment to transport and deposition, is described with rigor from the viewpoints of fluid dynamics and soil physics. The techniques for quantitative wind-erosion prediction through computational modelling constitutes a unique feature of this book in contrast to others published in the same field. For the first time, wind-erosion has been considered systematically as a multidisciplinary subject. The author has advocated the development of integrated wind-erosion modelling systems which couple dynamic models for the atmosphere and land surface with spatially distributed data for land-surface conditions. The successful applications of such a system have demonstrated its usefulness in wind-erosion assessment and prediction on regional to continental scales. This book offers a valuable reference point for researchers and postgraduate students engaged in wind-erosion related studies, ranging from global climate change to atmospheric aerosols, dust storms, air quality, and land conservation.

Principles of Soil Conservation and Management


Book Description

“Principles of Soil Management and Conservation” comprehensively reviews the state-of-knowledge on soil erosion and management. It discusses in detail soil conservation topics in relation to soil productivity, environment quality, and agronomic production. It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries. It also critically reviews information on no-till management, organic farming, crop residue management for industrial uses, conservation buffers (e.g., grass buffers, agroforestry systems), and the problem of hypoxia in the Gulf of Mexico and in other regions. This book uniquely addresses the global issues including carbon sequestration, net emissions of CO2, and erosion as a sink or source of C under different scenarios of soil management. It also deliberates the implications of the projected global warming on soil erosion and vice versa. The concern about global food security in relation to soil erosion and strategies for confronting the remaining problems in soil management and conservation are specifically addressed. This volume is suitable for both undergraduate and graduate students interested in understanding the principles of soil conservation and management. The book is also useful for practitioners, extension agents, soil conservationists, and policymakers as an important reference material.










Managing Agricultural Residues


Book Description

Many agriculturalists, conservationists, and environmentalists are stressing the importance of sustaining soil productivity so that future generations will have adequate productive land on which to produce food. One significant factor affecting soil productivity is the retention of crop residues on the surface of the soil to help control soil erosion. This book provides a review of the vast amount of literature on the subject, condensing the findings in a comprehensive, easy-to-understand manner. It focuses on topics such as erosion control, crop production in systems involving surface residues, residue use for fuel and animal feed, plant pathogens, insects, soil properties, and the economics of conservation tillage.
