With the renewed current emphasis on agricultural production efficiency and environmental quality, the technology of soil and plant analysis has taken on even greater importance. Several states now require soil testing as part of their nutrient management programs. Soil testing and plant analysis are important components of the Food Security Act and under consideration as safeguards for the new Clean Water Act. The Council on Soil Testing and Plant Analysis, established in 1969, promotes soil testing and plant analysis, including efficient use of nutrient resources, maximizing profits, and encouraging proper soil management and environmental protection. Compiled by the Council in response to the growing need for information about soil testing and plant analysis laboratories, Soil and Plant Analysis Laboratory Registry for the United States and Canada, Second Edition provides up-to-date information about public and private laboratory services, including:

Volcanic eruptions are generally viewed as agents of destruction, yet they provide the parent materials from which some of the most productive soils in the world are formed. The high productivity results from a combination of unique physical, chemical and mineralogical properties. The importance and uniqueness of volcanic ash soils are exemplified by the recent establishment of the Andisol soil order in Soil Taxonomy. This book provides the first comprehensive synthesis of all aspects of volcanic ash soils in a single volume. It contains in-depth coverage of important topics including terminology, morphology, genesis, classification, mineralogy, chemistry, physical properties, productivity and utilization. A wealth of data (37 tables, 81 figures, and Appendix) mainly from the Tohoku University Andisol Data Base is used to illustrate major concepts. Twelve color plates provide a valuable visual-aid and complement the text description of the world-wide distribution for volcanic ash soils.

This volume will serve as a valuable reference for soil scientists, plant scientists, ecologists and geochemists interested in biogeochemical processes occurring in soils derived form volcanic ejecta.

Providing an introduction, the scientific background, case studies and future perspectives of in-situ arsenic remediation technologies for soils, soil water and groundwater at geogenic and anthropogenic contaminated sites. The case studies present in-situ technologies about natural arsenic, specifically arsenate and arsenite, but also about organic arsenic compounds. This work covers geochemical, microbiological and plant ecological solutions for arsenic remediation. It will serve as a standard textbook for (post-)graduate students and researchers in the field of Environmental Sciences and Hydrogeochemistry as well as researchers, engineers, environmental scientists and chemists, toxicologists, medical scientists and even for general public seeking an in-depth view of arsenic which had been classed as a carcinogen. This book aims to stimulate awareness among administrators, policy makers and company executives of in-situ remediation technologies at sites contamined by arsenic and to improve the international cooperation on the subject.

For the last couple of decades it has been recognized that the foundation material on which a structure is constructed may interact dynamically with the structure during its response to dynamic excitation to the extent that the stresses and deflections in the system are modified from the values that would have been developed if it had been on a rigid foundations. This phenomenon is examined in detail in this book. The basic solutions are examined in time and frequency domains and finite element and boundary element solutions compared. Experimental investigations aimed at correlation and verification with theory are described in detail. A wide variety of SSI problems may be formulated and solved approximately-using simplified models in lieu of rigorous procedures; the book gives a good overview of these methods. A feature often lacking in other texts on the subject, is the way in which dynamic behaviour of soil can be modelled. Two contributors have addressed this problem from the computational and physical characterization viewpoints. The book illustrates practical areas with the analysis of tunnel linings and stiffness and damping of pile groups. Finally, design code provisions and derivation of design input motions complete this thorough overview of SSI in conventional engineering practice. Taken in its entirety the book, written by 15 well known experts, gives an in-depth review of soil-structure interaction across a broad spectrum of aspects usually not covered in a single volume. It should be a readily usable reference for the research worker as well as the advance level practitioner.

Conservation tillage systems have been adopted by farmers in many countries to solve the problem of land degradation and declining water productivity. Direct application of such tillage systems has not been possible among resource-poor, smallholder farmers in semi-arid areas of Ethiopia. Problems such as the lack of rainfall, the costs of herbicides and implements, and the special cultivation needs of the crop tef, which can not be planted in rows, have developed locally-adapted conservation tillage systems. This book considers traditional tillage systems and the results of tests carried out on appropriate conservation tillage implements and systems for smallholder farmers in semi-arid regions of Ethiopia. The traditional tillage implement, the Maresha Plough, and the related tillage systems were identified as being the main cause of repeated and cross-ploughing, leading to land degradation and reduced water productivity. Modified implements were found to be suitable for conservation tillage systems while being simple, light and affordable. Two types of tillage systems developed for maize and tef were found to reduce surface runoff, increase availability of water to crops and increase yields.

Residual soils are found in many parts of the world and are used extensively as construction materials for roads, embankments and dams, and to support the foundations of buildings, bridges and load-bearing pavements. The characteristics and engineering properties of residual soils can differ significantly from those of the more familiar transported soils. The fact that residual soils occur often in areas with tropical and sub-tropical climates and (extensively) in semi-arid climates, adds another dimension to their engineering performance, that of unsaturation. Although there are many books that deal with the mechanics of soils, these are based mainly on the characteristics and behaviour of saturated transported soils. The first edition of this book was the first book to be written specifically about the mechanics of residual soils. The book was prepared by a panel of authors drawn from the Technical Committee on Tropical and Residual Soils of the International Society for Soil Mechanics and Foundation Engineering. It was written as a practical professional guide for geotechnical engineers working with residual soils. The second edition has retained the valuable information contained in the first edition. The present editors and authors have extensively revised and augmented the content to bring it completely up to date, adding significantly to the sections on unsaturated soil mechanics and expanding the range and number of instructive case histories. Furthermore, sections on pedocretes, dispersive soils and karst have been added.

In these books, we bring together and correlate recent information known to have a prominent influence on the rate of movement of pollutants from wastes and their leachates in the soil. The emphasis is on those characteristics most amenable to modification and their management, such that secure and rational choices of disposal can be made. Identification of limits of the state of the art are carefully defined. This book presents five distinct but related subject matter sections. The first topic relates to soil as a natural system to prepare the reader with a basic knowledge of soil properties as they must become involved in waste management at the disposal facility. The soil, its depth-profile, and certain characteristics are identified and described.

The book will interest soil scientists, microbiologists, agronomists, and soil ecologists.

The increasing awareness of the effects of pollutants in the eco-system and on the development of suitable methods of analysis has stimulated a lot of research recently. This volume comprehensively discusses the range of methods available for the analysis and determination of organic compounds in soils, river and marine sediments and industrial sludges. A review is provided of the instrumentation used in soil and sediment laboratories and an indication of the types of organics that can be determined by each technique. Subsequent chapters discuss the analysis of various types of organics in a logical and systematic manner. Guidance is provided on the applicability of techniques in certain environments, the advantages and disadvantages of using one method over another, likely interference, the sensitivity of particular techniques, and detection limits. The work will be of interest to agricultural chemists, agriculturists concerned with ways in which organic chemicals used in crop or soil treatment permeate the ecosystem and to biologists and scientists involved in fish, plant and insect life. Toxicologists, public health workers, oceanographers, and environmentalists will also find the book beneficial.

Phyto presents the concepts of phytoremediation and phytotechnology in one comprehensive guide, illustrating when plants can be considered for the uptake, removal or mitigation of on-site pollutants. Current scientific case studies are covered, highlighting the advantages and limitations of plant-based cleanup. Typical contaminant groups found in the built environment are explained, and plant lists for mitigation of specific contaminants are included where applicable. This is the first book to address the benefits of phytotechnologies from a design point of view, taking complex scientific terms and translating the research into an easy-to-understand reference book for those involved in creating planting solutions. Typically, phytotechnology planting techniques are currently employed post-site contamination to help clean up already contaminated soil by taking advantage of the positive effects that plants can have upon harmful toxins and chemicals. This book presents a new concept to create projective planting designs with preventative phytotechnology abilities,phytobuffering where future pollution may be expected for particular site programs. Filled with tables, photographs and detailed drawings, Kennen and Kirkwood's text guides the reader through the process of selecting plants for their aesthetic and environmental qualities, combined with their contaminant-removal benefits.

A step-by-step text on the basic tests performed in soil mechanics, Introduction to Soil Mechanics Laboratory Testing provides procedural aids and elucidates industry standards. It also covers how to properly present data and document results. Containing numerical examples and figures, the information presented is based on American Society for Testing and Materials (ASTM) standards, and US Army Corps of Engineers engineering manuals. The authors discuss the different methods of in situ field methods and ex situ laboratory methods of soil description and identification. They present equations for the physical properties of soil and laboratory methods of soil classification. They also discuss tests for the interaction of soil and water, and hydraulic conductivity and consolidation. These tests produce information useful in the identification and characterization of soil samples and their engineering behaviors. A comprehensive resource, the book describes the evaluation of physical properties of soils, including mass, weight, unit weight, and mass density of the soil mass and its component phases. These properties are then expanded to define a number of weight and volumetric relationships. The book also discusses tests used in the evaluation of the density-water content relationships in soils and in the evaluation of the quality of compaction operations. These features and more make this book an excellent guide for testing soils.

Landscapes are characterized by a wide variation, both spatially and temporally, of tolerance and response to natural processes and anthropogenic stress. These tolerances and responses can be analyzed through individual landscape parameters, such as soils, vegetation, water, etc., or holistically through ecosystem or watershed studies. However, such approaches are both time consuming and costly. Soil erosion and landscape evolution modeling provide a simulation environment in which both the short- and long-term consequences of land-use activities and alternative land use strategies can be compared and evaluated. Such models provide the foundation for the development of land management decision support systems. Landscape Erosion and Evolution Modeling is a state-of-the-art, interdisciplinary volume addressing the broad theme of soil erosion and landscape evolution modeling from different philosophical and technical approaches, ranging from those developed from considerations of first-principle soil/water physics and mechanics to those developed empirically according to sets of behavioral or empirical rules deriving from field observations and measurements. The validation and calibration of models through field studies is also included. This volume will be essential reading for researchers in earth, environmental and ecosystem sciences, hydrology, civil engineering, forestry, soil science, agriculture and climate change studies. In addition, it will have direct relevance to the public and private land management communities.

The dissolution of the communist system led to the creation of new states and the formation of new concepts of citizenship in the post-Soviet states of Central and Eastern Europe. The formation of national identity also occurred in the context of the process of increasing economic and political globalisation, particularly the widening of the European Union to include the central European post-socialist and Baltic States. Internationally, Russia sought to establish a new identity either as a European or as a Eurasian society and had to accommodate the interests of a wider Russian Diaspora in the 'near abroad'. This book addresses how domestic elites (regional, political and economic) influenced the formation of national identities and the ways in which citizenship has been defined. A second component considers the external dimensions: the ways in which foreign elites influenced either directly or indirectly the concept of identity and the interaction with internal elites. The essays consider the role of the European Union in attempting to form a European identity. Moreover, the growing internationalisation of economies (privatisation, monetary harmonisation, dependence on trade) also had effects on the kind of 'national identity' sought by the new nation states as well as the defining by them of 'the other'. The collection focuses on the interrelations between social identity, state and citizenship formation, and the role of elites in defining the content of concepts in different post-communist societies. This book was originally published as a special issue of Europe-Asia Studies.
