This book was released on 1994 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely collection provides a general overview and detailed discussion of social and technical issues related to moving toward a culture and practice of sustainable agriculture in the American Midwest. It develops the concept that because agriculture does not exist in isolation, sustainability must be understood within the context of the many dynamic natural and social systems characteristic of a particular region - from climate to culture. Scholars from diverse disciplines - ecology, geography, economics, agricultural engineering, anthropology, entomology, climatology - provide the historical and contemporary context for this vital discussion.

Available in PDF, EPUB and Kindle. Book excerpt: Provides readers with the fundamentals necessary for a basic understanding of the soil landscape. Divided into three major sections, it covers stratigraphy, geomorphology, hydrology, and the ways in which these geologic processes shape the landscape. Early chapters cover the textural characteristics of soil materials, fluvial systems, hillslope sediments and transitional environments. Later chapters explore volcanics, saprolite, the evolutionary process of landscapes, rates of denudation, streams, hillslope processes and mass movement. Included at the end of the chapters are lists of references, figures, tables and additional reading sources.
Download or read book Themes in Biogeography written by J. A. Taylor and published by Routledge. This book was released on 2019-10-01 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1984, Themes in Biogeography presents a broad examination of biogeographical themes, extending across the field of plant and animal ecology and geography. The book provides a detailed and unique investigation into life and its environment and delves into not just geography, and ecology, but provides an interdisciplinary look at these areas across both biological and environmental sciences. The book examines biogeographical themes applying them to areas of research in soils and climate change, as well as in depth studies of plant communities and their animal associates. The book also discusses plants and animals through their taxonomic distribution, and deals with factors of plant geography, using both global and regional examples. This book will be of interest to biologists, ecologists and geographers alike.

Download or read book Soil Physical Conditions and Plant Roots written by J. Glinski and published by CRC Press. This book was released on 2018-01-17 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a specialized monograph on soil physical conditions and root-system relations. It attempts to explain the importance of physical properties of soil by showing how they affect root growth and functions; and on the other hand, how roots themselves change their environment. Emphasis is placed on the interactive effects of soil physical factors. An attempt has been made to analyze the possibilities of the root system‘s modification by both soil and plant management.The book is addressed to research workers and advanced students in soil and plant sciences and may also be of interest to agronomists and related specialists.

Download or read book Restoration and Development of the Degraded Loess Plateau China written by Atsushi Tsunekawa and published by Springer Science & Business Media. This book was released on 2013-08-23 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents state-of-the-art scientific evidence and technological innovations to restore lands on the Loess Plateau of China, known worldwide for its serious land degradation and desertification problems. Supported by a rapidly developing Chinese economy and the dissemination of effective technology, the Grain-for-Green Project and Western Development Action launched by the Chinese government have resulted in successful ecological restoration and protection over the past 30 years. These programs have contributed not only to conservation of soil and water, but also to economic development. At the same time, however, these developmental interventions have brought new challenges that have not yet been fully addressed. The book describes (1) case studies of success and failure in practice, including rare success stories of combating desertification; (2) technical issues such as erosion control and breeding of stress-tolerant plant species, and socioeconomic measures taken by the Chinese government and lending policies with support from the World Bank; and (3) comprehensive measures against desertification, such as water and wind erosion, salinization, and deforestation. This volume is recommended for researchers and students above the undergraduate level in diverse fields including soil science, rural engineering, social technology and civil engineering, biology, ecology, climatology, physical and human geography, and developmental economics, among others. It also serves as a valuable resource for engineers, government officials, and NPOs and NGOs involved in afforestation, ecological restoration, combating desertification, disaster prevention, and sustainable rural development.
Download or read book Managing Agricultural Residues written by Paul W. Unger and published by CRC Press. This book was released on 1994-03-16 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Aeolian Dust and Dust Deposits written by Kenneth Pye and published by Elsevier. This book was released on 2015-07-14 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aeolian Dust and Dust Deposits explores the entrainment, dispersion, and deposition of aeolian dust and dust deposits, with emphasis on transport and deposition of dust derived by deflation of surface sediments and soils. Topics covered range from the mechanisms of fine-particle formation to dust sources, sinks, and rates of deposition. Dust-transporting wind systems are also discussed, along with the grain size, mineralogy, and chemical composition of aeolian dust. Comprised of nine chapters, this book begins with an overview of the general nature and significance of windborne dust as well as the importance of aeolian dust and loess. The next chapter deals with the mechanisms underlying the formation of fine particles, including glacial grinding, frost and salt weathering, and fluvial comminution. The reader is then introduced to dust entrainment, transport, and deposition, together with dust sources, sinks, and rates of deposition. Subsequent chapters focus on the implications of dust deflation, transport, and deposition; dust deposition in the oceans; and loess distribution and the thickness and morphology of loess deposits. This monograph is written primarily for research workers and advanced students in sedimentology, geomorphology, and Quaternary studies, but is also likely to be of value to soil scientists, meteorologists, planetary geologists, engineers, and others concerned with environmental management.
Download or read book The Present Past written by Ian Hodder and published by Pen and Sword. This book was released on 2012-11-05 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This updated edition of Professor Ian Hodders original and classic work on the role which anthropology must play in the interpretation of the archaeological record. There has long been a need for archaeologists and anthropologists to correlate their ideas and methods for interpreting the material culture of past civilisations. Archaeological interpretation of the past is inevitably based on the ideas and experiences of the present and the use of such ethnographic analogy has been widely adapted and criticised, not least in Britain. In this challenging study, Ian Hodder questions the assumptions, values and methods which have been too readily accepted. At the same time, he shows how anthropology can be applied to archaeology. He examines the criteria for the proper use of analogy and, in particular, emphasises the need to consider the meaning and interpretation of material cultures within the total social and cultural contexts. He discusses anthropological models of refuse deposits, technology and production, subsistence, settlement, burial, trade exchange, art form and ritual; he then considers their application to comparable archaeological data. Throughout, Professor Hodder emphasises the need for a truly scientific approach and a critical self-awareness by archaeologists, who should be prepared to study their own social and cultural context, not least their own attitudes to the present-day material world.
