Book Description
Processes of acidification or alkalization of soils are treated, taking the qualitative changes in soil chemistry into consideration. Following a theoretical background of ecosystem proton budgets, the application for assessing external and internal acid loads are demonstrated. The chemistry of organic matter and the oxides of aluminum, iron, and manganese are treated in the context of being sources and sinks for acid loads in soils. Special attention is payed to the assessment of solubility and reaction kinetics of aluminous minerals. The formation of toxic elements in soil solution resulting from the solubilization of inorganic oxides as well as aspects of changes in the nutrient status of soils, changes of fertility and processes leading to a transfer of acidity from soils to surface are discussed.

Book Description
Soil Acidity and Plant Growth emerged from concerns over increasing acidification of soils under improved pastures over wide areas of southern Australia. While the book has its origin in the problems of acidification of Australian soils under pastures, the authors examine soil acidity within a much broader framework, making their views relevant to all agricultural and natural ecosystems on acid soils. The book's first two chapters discuss the chemistry of soil acidity and the ecological processes leading to it. This is followed by separate chapters on biological responses to soil acidity, covering mineralization of soil nitrogen, incidence of plant diseases, plant mycorrhizal associations, symbiotic nitrogen fixation in legumes, and genetic variability in plant response to toxicities. The remaining chapters focus on the correction of soil acidity problems by liming. These include studies on the rates of application and effectiveness of liming materials; and the development and use of computer modelling procedures to help researchers identify the effects and interactions of soil pH on component processes and to provide assistance to farmers in the management of long-term subterranean clover pastures.

Book Description
Soil Acidity is one of the major intrinsic soil-related constraints limiting the production potential of these soils for crop growth. About 30 million hectares of cultivated land in the country is highly acidic with soil pH ranging from 4.5 to 5.5. Crop diversity, cropping intensity, crop productivity & profitability in these areas are very low, resulting in livelihood insecurity, poverty, and slow pace of development. The Chemistry of soil acidity has been one of the much researched domains in Soil Science. The book covers various management practices with practical application in the cultivation of these soils for diverse crops and cropping systems and plantation crops. Emphasis has been laid on amelioration of Acid soils and nutrient use in crops to improve the agricultural productivity. Problems and prospects of suitable soil amendments, their availability, quality and cost have been discussed in detail. s for the book have been written by scientists, who are engaged in this work for the past two to three decades. the “Way Forward” suggests the Technology and steps to be taken for managing such soils and the expected economic gain, so that the State Governments draw the needed Action Plan and implement them with all seriousness

Book Description
The majority of this book was written in 1983-84 while the senior author was a Visiting Scientist at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. We believe that the approach to the problem of acid deposition effects on soils and waters developed during this collaboration contains ele ments that are significantly different from most prior work in this area. Some of the material and the software used in the development of these concepts stem from earlier individual efforts of the authors. However, what we believe to be the more significant concepts concerning the processes by which alkalinity may be developed in acid soil solutions, and by which acid deposition may contrib ute to the loss of this alkalinity, were the result of this collaboration. The ultimate usefulness of these concepts in understanding and dealing with various aspects of the problems associated with acid deposition cannot be adequately gauged at the present time. They must first withstand tests of con sistency with available observation, and of direct experimentation. It is our hope that dissemination through this book will facilitate this process within the scientific community. The authors wish to thank the administration of the Environmental Science Division at ORNL, and the College of Agricultural Sciences at Colorado State University for their support in arranging this collaboration. We also wish to express our appreciation for the financial support provided by EPA. Personal thanks are due to Dr.
