- Problem der Bodenerosion wird hier mit ganzheitlichem Ansatz besprochen - Ursachen und Auswirkungen der Erosion werden in sozialökonomischen Kontext gebracht - ausführliche Angaben über Methoden der Verfolgung von Bodenerosion (GPS, GIS, Erdfernerkundung) - mit einer gut verständlichen allgemeinen Einführung in Bodenkunde und Hydrologie

Common Grasses, Legumes and Forbs of the Eastern United States: Identification and Adaptation presents photographic identification of the most important grassland, turf, and noncrop plants, and their seeds to facilitate quick identification in the field. Unlike many publications that focus solely on floral identification, this book emphasizes vegetative identification as well to allow for accurate plant identification year-round. The book includes 23 forage legumes, 61 grasses, and more than 100 nonleguminous forbs found in pastures and grasslands of Eastern United States. In addition to identification of important species, the book describes other key characteristics such as adaptation, favorable and unfavorable soil types, seasonal growth patterns, and toxicity. For plants harvested for hay or silage or by grazing, the book also discusses cutting and grazing management, quality factors, and potential yields. Through its practical approach and comprehensive structure, Common Grasses, Legumes and Forbs of the Eastern United States is a valuable reference for farm advisors, teachers and students of agronomy, and for anyone interested in the dynamic relationship between plants and agriculture. - Features full-color illustrations of both seed and plant, allowing for rapid identification at multiple stages of development - Presents various identification methods and use cases for over 180 plants - Details seasonal growth patterns and toxicity, as well as favorable and unfavorable soil types - Discusses cutting and grazing management

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.

This book reviews the major achievements recently made in soil erosion and sediment redistribution research and management, and identifies future requirements. The book presents work from key players in river basin soil erosion and sediment redistribution from sources to sinks, field to riverbank, from academia to policy and industry. It examines the developments made in three themes - measurement, modelling and management - and covers a variety of scales (in both time and space) and geographical locations.

This book is used as a required text for undergraduate, graduate, and short courses in many countries. It represents the most updated material in the field of erosion/sediment control and the recovery of degraded land, being a handy tool for researchers, educators, consultants, expert witnesses, and students in general.

“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.
