"Sodic soils cover almost a third of the total land in Australia and are represented to some extent on all continents except Antarctica. They can occur naturally, as in Australia, or may develop as a result of the removal of salts from saline soils." "Sodicity impacts adversely on many soil properties and interferes with the proper functioning of the soil and of the plants grown in it. Problems arise as a result of the deterioration in soil structure, decreased retention and availability of water, decreased nutrient availability and impaired biological activity. Sodic soils are easily eroded and this causes severe land degradation and pollution of water resources." "The management of sodic soils is often difficult and challenging. Because they are so widespread in Australia, their impact on productivity is immense." "Australian Sodic Soils: Distribution, Properties and Management brings together for the first time the results of scientific studies carried out in Australia and presented at the first national conference on Australian sodic soils."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Soil Analysis: An Interpretation Manual is a practical guide to soil tests. It considers what soil tests are, when they can be used reliably and consistently, and discusses what limits their application. It is the first nationally accepted publication that is appropriate for Australian soils and conditions. The first three chapters review the general principles and concepts of soil testing, factors affecting soil test interpretation and soil sampling and handling procedures. The next two chapters describe morphological indicators of soil and include colour plates of major Australian agricultural soils. These are followed by a series of chapters which present soil test calibration data for individual elements or a related group of tests such as the range of soil tests used to interpret soil acidity. Each of these chapters also summarises the reactions of the particular element or parameter in the soil and describes the tests commonly used in Australia. The final chapter presents a structured approach to nutrient management and making fertiliser recommendations using soil test data. The manual will be of particular interest to soil and environmental scientists, farm advisers, consultants and primary producers who will find the manual an essential reference to understanding and interpreting soil test data. Many of the soil tests evaluated in the book are used throughout the world. Soil Analysis: An Interpretation Manual was commissioned and developed by the Australian Soil and Plant Analysis Council (ASPAC). It comprises the work of 37 experts, which has been extensively peer reviewed.

The complex issues involved in the management of saline and sodic turfgrass soils are enough to perplex even the most experienced site manager — there is no "silver bullet" amendment, treatment, or grass for salinity management. Best Management Practices for Saline and Sodic Turfgrass Soils: Assessment and Reclamation presents comprehensive scientific principles and detailed, practical management and assessment recommendations for turfgrass and landscape sites. The authors use the Best Management Practices (BMPs) concept, considered the gold-standard management approach for any individual environmental issue, since it is a whole ecosystem (holistic), science-based salinity management approach that allows all possible management options to be considered and implemented on a site-specific basis. They identify BMP strategies, including irrigation system design; irrigation scheduling and salinity leaching; chemical, physical, and biological amendments; cultivation; topdressing; soil modification; sand-capping; surface and subsurface drainage options; nutritional practices; additional cultural practices; and ongoing monitoring. The book presents emerging challenges, technology, and concepts that address integration of salinity management into comprehensive site environmental or sustainable management systems, use of halophytic turfgrasses for non-traditional purposes, integration of geospatial and geostatistical concepts and technology, and integration of new sensor technology into daily management paradigms. Outlining a holistic BMP approach, the book incorporates scientific principles and practical management recommendations and details specific salinity challenges and the logic behind each BMP strategy for salinity management, with an emphasis on actual field problems. The book is formatted for flexible use, with stand-alone chapters that include outlines for quick review of a topic for those requiring only a basic understanding as well as in-depth discussions of the science and practical aspects for those seeking a more rigorous treatment. It supplies a single source for all the information required to identify and manage diverse types of salinity stresses.

This essential reference provides an introduction to the remarkable soils and landscapes of Australia. It reveals their great diversity and explains why an understanding of soil properties and landscape processes should guide our use of the land. Using striking photographs of characteristic landscapes, it begins by describing the basic properties of soils and how Australia's distinctive soils and landscapes have co-evolved. We gain a greater understanding of why particular soils occur at certain locations and how soil variation can influence landscape processes, agricultural productivity and ecosystem function. The book explains the impact of various forms of land use and the changes they can bring about in soil. This is followed by an invaluable compendium that describes and illustrates over 100 of the more important and widespread soils of Australia, along with their associated landscapes. There is a brief account of each soil's environment, usage and qualities as well as details on chemical and physical properties so we can make more informed decisions about appropriate land-use. Australian Soils and Landscapes will be a valuable resource for farmers, natural resource managers, soil and environmental scientists, students and anyone with an interest in Australia's unique environment.
