Provide a European forum for the dissemination and exchange of knowledge and ideas about contaminated land arising from industrial and commercial activities;

Identify research needs and promote collaborative research that will enable European industry to identify, assess and manage contaminated sites more efficiently and cost-effectively; and

Collaborate with other international networks inside and outside Europe and encompass the views of a wide a range of interest groups and stakeholders (for example, land developers, local/regional regulators and the insurance/financial investment community). More: www.nicole.org

Anthropogenic Soils in Soil Taxonomy

ICOMANTH (International Committee for Anthropogenic Soils) has drafted a 7th Circular Letter to introduce classes to recognize human-altered or transported soils. If you have interest, your constructive feedback is welcome. We have posted this Circular at http://clic.cses.vt.edu/soils/~ICOMANTH  The main proposals concern how to recognize and classify deposits of human-transported material 50 cm or more thick. These changes are referenced to pages in the 11th Ed. of the Keys to Soil Taxonomy found online. Please response to john.galbraith@vt.edu  

Universal Soil Classification

At the recent World Congress, the International Union of Soil Sciences leadership unanimously supported the formation of a Working Group to research the potential of developing a Universal Soil Classification System.  The Working Group is chaired by Jon Hempel, USDA-NRCS Jon.hempel@lin.usda.gov  in Lincoln, NE and vice chaired by Erika Micheli, Head Department of Soil Science and Agricultural Chemistry, Szent Istvan University Godollo, Hungary Micheli.Erika@mkk.szie.hu   It is the vision for the Working Group to consist of any and all Pedologists that have an interest in this important topic.  A small core group of Pedologists geographically representing the International Soil Science Community has been assembled and is scheduled to meet in the spring of 2011 to begin the discussion. The following link provides  background information relating to the Universal Soil Classification and the  Working Group: ftp://ftp-fc.sc.egov.usda.gov/NSSC/Universal_Soil_Classification_Background/

Soil organic carbon (SOC) dynamics at different spatial scales. Convener: Bas van Wesemael. Co-Conveners: Kristof Van Oost, Jens Leifeld. Soils are one of the largest carbon pools and a small change in SOC content could therefore substantially intensify, or mitigate, current atmospheric CO2 increase. The discrepancies in CO2 fluxes from studies using different techniques also emerge. A crucial problem is therefore the linkage between the scale at which we understand processes and develop models (profile scale, short term) and larger scale observations at longer time scales: the spatial aggregation of current approaches induces averaging out of soil conditions and therefore does not allow to incorporate effects of past land management, lateral fluxes of water and/or carbon within the spatial units for which the models are run or the SOC values are averaged. Such landscape processes will need to be reflected in both regional SOC inventories and modeling. For more details http://meetingorganizer.copernicus.org/EGU2011/session/7745

The book discusses the assessment of the natural/background content of trace elements in soil, bioindication of the chemical status of environmental compartments, soil remediation, and hyperaccumulation and phytoextraction of trace metals from the soil. The table of contents reflects the IUPAC's recommendation for numbering element groups, giving the new edition an updated organizational flow.
 
Growth and Mineral Nutrition of Field Crops, Third Edition, by Nand Kumar Fageria, EMBRAPA, San Antonio de Goias, GO, Brazil; Virupax, Baligar, USDA/ARS SPCL, Beltsville, MD, USA; Charles Allan Jones, Texas A&M University, Dallas, USA. CRC Press. ISBN:  9781439816950. By the year 2050, the world's population is expected to reach nine billion. To feed and sustain this projected population, world food production must increase by at least 50 percent on much of the same land that we farm today. To meet this staggering challenge, scientists must develop the technology required to achieve an "evergreen" revolution, one that increases crop productivity without degrading natural resources. With 30 percent new material, the updated and revised third edition of Growth and Mineral Nutrition of Field Crops covers all aspects of crop growth and mineral nutrition that contribute to sustainable, high-yield agriculture. Bringing together international scientific knowledge of crop production and the impacts of agriculture on the environment, this book: Includes two new chapters on remediation of heavy-metal contaminated soils and cover crops; Covers theoretical and practical aspects of mineral nutrition of field crops; Provides recommendations for judicious use of fertilizers, which will reduce cost of crop production and enhance high crop yields without risking environmental pollution; Provides growth patterns for annual crops and forages; Includes a handful of color pictures of nutrient deficiencies for easy diagnostic purposes. To make the book as practical as possible, each chapter is supported by experimental results and extensive references. A large number of figures and tables are also included to save readers time when researching. The overall emphasis of this reference is on the soil's ability to sustain high crop yields and a healthy human population.

Facts About Global Warming. Rational or Emotional Issue? By Kut?lek, Miroslav and Nielsen, Donald R., 2010, 227 pp. Essays in GeoEcology, Catena Verlag GMBH, Reiskirchen, Germany. ISBN 978-3-923381-58-6, US ISBN 1-59326-242-0. Price 45.00  + mailing costs. The book is an essay about a politically abused problem which is not only a subject of climatologists but of utmost interest for researchers in the fields of Soil Science, Hydrology and Environmental Science dealing with the principles of sustaining life on our planet. In an easily understandable presentation the authors discuss comprehensive reports and peer-reviewed scientific publications on global warming, and how temperature of earlier time is estimated when thermometers did not exist. The underestimation of temperature of the Medieval Warm Period in many climatologic studies is critically reported. Stating that greenhouse effect is not the dominant cause of the recent climate change, the authors explain the role of eight factors acting upon the climate in the geological history of planet Earth. They show that climate change was important in man's evolution and in the development and crisis of civilizations. They do not consider the recent magnitude and speed of warming as a signal of an approaching catastrophe. Their analyses of analogical warming oscillations in the Holocene are found not to be dangerous for life, but quite the opposite. The catastrophic scenarios of approaching disasters caused by global warming are rationally rejected at the end.

Soil Enzymology. Series: Soil Biology, Vol. 22. Shukla, Girish; Varma, Ajit (Eds.) 1st Edition., 2011, XVI, 385 p., Hardcover. ISBN: 978-3-642-14224-6. Soil enzymes are one of the vital key mediators involved in nutrient recycling and the decomposition of organic matter and thereby in maintaining soil quality and fertility. This Soil Biology volume covers the various facets of soil enzymes, such as their functions, biochemical and microbiological properties and the factors affecting their activities. Enzymes in the rhizosphere, in forest soils, and in volcanic ash-derived soils are described. Soil enzymes covered include phosphohydrolases, lignocellulose-degrading enzymes, phenol oxidases, fungal oxidoreductases, keratinases, pectinases, xylanases, lipases and pectinases. Several chapters treat the soil enzymatic activities in the bioremediation of soils contaminated with pesticides and pollutants such as oil, chlorinated compounds, synthetic dyes and aromatic hydrocarbons. The role of soil enzymes as bioindicators is a further important topic addressed.
