Book Description
"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.

Book Description
It is well known that arid-land soils are adversely affected by the presence of sodium, yet only recently has the behavior of sodium in the soils of humid and subhumid areas --where most of the world's cereal crop is grown--been recognized. This book of commissioned chapters will focus on the "non-classic" sodic soils, describing the processes of soil degradation resulting from sodium and other deleterious components (such as magnesium), and outlining strategies for ameliorating their effects on soil systems.

Book Description
The Australian Soil Classification provides a framework for organising knowledge about Australian soils by allocating soils to classes via a key. Since its publication in 1996, this book has been widely adopted and formally endorsed as the official national system. It has provided a means of communication among scientists and land managers and has proven to be of particular value in land resource survey and research programs, environmental studies and education. Classification is a basic requirement of all science and needs to be periodically revised as knowledge increases. This Second Edition of The Australian Soil Classification includes updates from a working group of the National Committee on Soil and Terrain (NCST), especially in regards to new knowledge about acid sulfate soils (sulfidic materials). Modifications include expanding the classification to incorporate different kinds of sulfidic materials, the introduction of subaqueous soils as well as new Vertosol subgroups, new Hydrosol family criteria and the consistent use of the term reticulate. All soil orders except for Ferrosols and Sodosols are affected by the changes.

Book Description
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 scientif

Book Description
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.

Book Description
This edited volume focuses on the characterization, reclamation, bioremediation, and phytoremediation of salt affected soils and waterlogged sodic soils. Innovative technologies in managing marginal salt affected lands merit immediate attention in the light of climate change and its impact on crop productivity and environment. The decision-making process related to reclamation and management of vast areas of salt affected soils encompasses consideration of economic viability, environmental sustainability, and social acceptability of different approaches. The chapters in this book highlight the significant environmental and social impacts of different ameliorative techniques used to manage salt affected soils. Readers will discover new knowledge on the distribution, reactions, changes in bio-chemical properties and microbial ecology of salt affected soils through case studies exploring Indian soils. The contributions presented by experts shed new light on techniques such as the restoration of degraded lands by growing halophyte plant species, diversification of crops and introduction of microbes for remediation of salt infested soils, and the use of fluorescent pseudomonads for enhancing crop yields.
