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 Mechanics and Related Processes in Structured Agricultural Soils written by W.E. Larson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural soils are subjected to many applied mechanical stresses that influence their behavior. Stresses arise from tillage machines, seeders and chemicals applicators, tractors, and equipment for harvest and transport. Applied stresses may compact or loosen the bulk soil. Micro sections of soil (aggregates or clods) may be compacted during tillage while the bulk soil is loosened. Because most granular soils are combined into structural units of varying sizes with different strengths and properties, prediction of the effect of stresses on the behavior of bulk soils is difficult. The basic strength properties of soil are determined by many fac tors: the size distribution of particles, chemical and mineralogical properties of inorganic clay fraction, the organic matter content and composition, the water content and the stress history. These factors combine and interact to produce many possible behavior patterns. Changes in structure of the soil from applied stresses and biologi cal reactions may profoundly influence storage and transmission of water, heat, and air, and the mechanical resistance to penetration by plant roots. They may also affect the traction of vehicles. Manipulation of structural properties of soils by tillage implements is a major cost under most crop production systems. Reduced energy use is also a significant conservation objective. Improved management systems are very dependent upon a better understanding of soils' response to applied stresses. The content of this book resulted from a NATO Advanced Research Workshop held in St. Paul, Minnesota, U.S.A. September 13-16, 1988.

Download or read book Soil Structure written by Bobby A. Stewart and published by CRC Press. This book was released on 1995-06-13 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil Structure offers a multidisciplinary approach to the study of soil structure and its relevance to wide ranging investigations in environmental sciences. Topics covered in Soil Structure include soil structure determination, soil fabric genesis and functions, strength and stress distribution, fabric changes in plastic clays, the effects of organic matter and earthworms, air slaking, and hydraulic conductivity changes. The book also discusses litter decomposition and matter transport, the characterization of pore organization, monitoring via a neutron activated tracer, various influences on growth and phosphorus supply of plants and on water uptake by plants, the effects of acidification, and much more. Improved procedures for measuring and calculating the unsaturated hydraulic conductivity of structured soils are also given.

Download or read book Encyclopedia of Agrophysics written by Jan Gliński and published by Springer Science & Business Media. This book was released on 2011-06-07 with total page 1075 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Agrophysics will provide up-to-date information on the physical properties and processes affecting the quality of the environment and plant production. It will be a "first-up" volume which will nicely complement the recently published Encyclopedia of Soil Science, (November 2007) which was published in the same series. In a single authoritative volume a collection of about 250 informative articles and ca 400 glossary terms covering all aspects of agrophysics will be presented. The authors will be renowned specialists in various aspects in agrophysics from a wide variety of countries. Agrophysics is important both for research and practical use not only in agriculture, but also in areas like environmental science, land reclamation, food processing etc. Agrophysics is a relatively new interdisciplinary field closely related to Agrochemistry, Agrobiology, Agroclimatology and Agroecology. Nowadays it has been fully accepted as an agricultural and environmental discipline. As such this Encyclopedia volume will be an indispensable working tool for scientists and practitioners from different disciplines, like agriculture, soil science, geosciences, environmental science, geography, and engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agriculture embodies many concepts in its attempt to integrate all the aspects of farming systems into a holistic system. This book explores the processes that occur within the components of a sustainable system and shows where we can build upon our existing knowledge to develop the concepts of sustainable agriculture into the new conventional agriculture. Well-known researchers examine a variety of aspects, including production goals, environmental considerations, and economics, to build a knowledge base that allows readers to see where changes in agriculture must be made and how challenges can be met. They compare existing systems against definitions of sustainability and pinpoint those areas where improvements can be made in current systems to further the concepts of sustainability.

Download or read book The Soils of Chile written by Manuel Casanova and published by Springer Science & Business Media. This book was released on 2013-01-18 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for students and soil scientists who want to know about the state of the art in soil sciences in Chile. The book merges a comprehensive bibliographical review of the soil surveys carried out throughout the length and breadth of Chilean territory during the past 40 years and more recent information obtained by the authors in a number of field studies. As its starting point the book presents a general overview of important features related to Chilean soils, such as geology and geomorphology, climate, land use and vegetation. In this long and narrow country different soil formation factors and processes have resulted in a broad variety of soil bodies, from the extremely arid Atacama desert to the Patagonian and Antarctic zones. This book provides a description and classification (mainly Soil Taxonomy) of the most important soil types. Particularly important are soils derived from volcanic materials, which cover extensive areas of Chile. The book also deals with soil management topics in relation to the chemical, physical and biological properties of Chilean soils and it includes a number of examples from throughout the country. Finally, the book shows how man has induced severe soil degradation problems in Chile, such as erosive soil degradation, non-erosive soil degradation and land desertification.
