Available in PDF, EPUB and Kindle. Book excerpt: Knowledge in the field of acidic deposition is expanding rapidly, and both ex perts and non-experts are challenged to keep up with the latest information. We designed our assessment to include both the basic foundation needed by non experts and the detailed information needed by experts. Our assessment in cludes background information on acidic deposition (Chapter 1), an in-depth discussion of the nature of soil acidity and ecosystem H+ budgets (Chapter 2), and a summary of rates of deposition in the Southeastern U.S. (Chapter 3). A discussion of the nature of forest soils in the region (Chapter 4) is followed by an overview of previous assessments of soil sensitivity to acidification (Chapter 5). The potential impacts of acidic deposition on forest nutrition are described in the context of the degree of current nutrient limitation on forest productivity (Chap ter 6). The results of simulations with the MAGIC model provided evaluations of the likely sensitivity of a variety of soils representative of forest soils in the South (Chapter 7), as well as a test of soil sensitivity criteria. Our synthesis and recommendations for research (Chapter 8) also serve as an executive summary. A complementary volume in the Springer-Verlag Ecological Studies series should be consulted for information on European forests. This volume, Acidic Deposition and Forest Decline in the Fictelgebirge, edited by E.-D. Schultze and O.L. Lange, also provides greater detail on the physiologic responses of trees than we present in our regional assessment.
Download or read book Soil Acidity and Plant Growth written by A Robson and published by Elsevier. This book was released on 2012-12-02 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Crop Production in Acidic Environment written by Dharmendra Singh and published by . This book was released on 2016 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil acidity is one of the major problems for crop production in many parts of the world. Poor crop productivity and soil fertility in acid soils are mainly due to a combination of aluminum and manganese toxicities and nutrient deficiencies (mainly deficiencies in P, Ca, Mg and K). Among these problems, aluminum toxicity is one of the major factors limiting crop production in acidic soils. Aluminum, the third most abundant metal in the earth's crust, poses a serious threat to crop productivity in acidic soils. It covers approximately 40 per cent area of the earth's arable land (Ma et al. 2011). Aluminum exists in nature as mononuclear, polynuclear and also as low molecular weight complexes. However, mononuclear is considered as highly toxic as compared to other forms (Taylor 1991, Kinraide 1993). When the soil pH drops below 5.0, aluminum is solubilized as the phytotoxic Al3+ species from non-toxic aluminum silicates and oxides (Lindsay 1979). The mobility of aluminum increases sharply with the reduction in the availability of exchangeable cations such as Ca2+, Mg2+ and K+ (Parker et al. 1989). The high mobility of aluminum is seen in Kaolinite rich soils at pH levels as high as 5.5 (Alam and Adams 1979, Foy 1974. Roy et al. 1988). The toxicity will be acute at pH 4.1 in soils than at pH 4.5. However, in nutrient solutions, aluminum toxicity is more severe at pH 4.5 than at 4.0 due to the formation of A1(OH)2+ ions, which are more toxic than A13+ itself (Moore 1974).

Download or read book Plant Soil Interactions at Low pH Principles and Management written by R.A. Date and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: The understanding of plant-soil interactions in acid soils is important for improved food production in many parts of the world. The context of the book touches on basic and applied aspects of the physics, chemistry and biology of acid soils and their effect on growth of plants. It contains a large section on management of acid soils for plant (food) production and on socioeconomic aspects of management of acid soils. This is important because a large portion of the world's acid soils occurs in less developed countries. Plant-Soil Interactions at Low pH: Principles and Management contains a substantial number of papers, including nine invited reviews, presented at the Third International Symposium of Plant-Soil Interactions at Low pH. The major themes include chemistry and physics of acid soils, microbial and faunal activity in acid soils, mechanisms of acid tolerance of plants, selection and breeding of acid-tolerant plants, diagnosis and correction of acid soil infertility, socioeconomic aspects of acid soil management and management systems for agriculture, horticulture and forestry on acid soils.

This book was released on 2018-04-30 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.
