10 pages, 1 figure, 1 table, 60 references.-- Trabajo publicado en la Section 2: Country Reports.-- El volumen consta de 202 páginas.-- Meeting at Soil Survey and Land Research Centre Cranfield University, Silsoe, UK., que tuvo lugar del 21-22, abril, 1998. ; Meetings of European Union Heads of Soil Survey Organisations were held in 1989 and 1994 respectively. Both were followed by publication of monographs describing the state-of-the-art in each of the member countries (Hodgson 1991; Le Bas & Jamagne 1996). Limited progress has been made in Spain since then, except for a proposal for an ambitious macroproject (PNCTA), the prospects for which now seem somewhat uncertain. Readers interested in historical aspects of Spanish pedology and/or soil mapping can refer to studies by Díaz Fierros (1979 and 1997) Mudarra (1989 and 1994); Sunyer (1996), Ibáñez el al. (1991, 1997), Boixadera and Ibáñez, (1996) and Guerra, (1997). This paper describes progress in soil survey from 1994 to 1998 and provides additional information on monitoring and soil databases developed in Spain. Nevertheless, some Spanish soil databases arising from some initiatives in Pan-European programmes are not included in the discussion here due to their particular scope. The Spanish contribution to the ICP Forest programme, recently published on a CD-ROM that holds morphological, taxonomic and analytical information corresponding to 453 soil profiles, is a case in point (Montoya & López-Arias, 1998). ; Peer reviewed

The possibility of using microbiological indicators of soil «health» to assess the soils. Th e fundamental possibility of quantitative characterization of the functional potential of the microbial system with the assessment of «ecological services» is shown. Thermodynamic criteria of natural microbial system (exergy and specific exergy) allow to carry out diagnostics of soil condition with direct estimation of degradation and damage. System characteristics of soil microbiota allow to approach the solution of many topical problems of functional soil science.

"This book introduces the concept of soil security and its five dimensions: Capability, Capital, Condition, Connectivity and Codification. These five dimensions make it possible to understand soil's role in delivering ecosystem services and to quantify soil resource by measuring, mapping, modeling and managing it. Each dimension refers to a specific aspect: contribution to global challenges (Capability), value of the soil (Capital), current state of the soil (Condition), how people are connected to the soil (Connectivity) and development of good policy (Codification). This book considers soil security as an integral part of meeting the ongoing challenge to maintain human health and secure our planet's sustainability. The concept of soil security helps to achieve the need to maintain and improve the world's soil for the purpose of producing food, fiber and freshwater, and contributing to energy and climate sustainability. At the same time it helps to maintain biodiversity and protects ecosystem goods and services"--Page 4 of cover

Few topics cut across the soil science discipline wider than research on soil carbon. This book contains 48 chapters that focus on novel and exciting aspects of soil carbon research from all over the world. It includes review papers by global leaders in soil carbon research, and the book ends with a list and discussion of global soil carbon research priorities.Chapters are loosely grouped in four sections: - Soil carbon in space and time - Soil carbon properties and processes - Soil use and carbon management - Soil carbon and the environment A wide variety of topics is included: soil carbon modelling, measurement, monitoring, microbial dynamics, soil carbon management and 12 chapters focus on national or regional soil carbon stock assessments. The book provides up-to-date information for researchers interested in soil carbon in relation to climate change and to researchers that are interested in soil carbon for the maintenance of soil quality and fertility. Papers in this book were presented at the IUSS Global Soil C Conference that was held at the University of Wisconsin-Madison, USA.

The agricultural world has changed significantly during the last years. The excessive use of heavy machinery, waste disposal, the use of agrochemicals and new soil cultivation means led to severe problems, which agricultural engineers have to cope with in order to prevent soil from permanent irreversible damage.This Soil Biology volume will update readers on several cutting-edge aspects of sustainable soil engineering including topics such as: soil compaction, soil density increases, soil disturbance and soil fragmentation; soil tillage machineries and optimization of tillage tools; soil traff

From the outside, soil may just look like a pile of dirt. Up close, however, it's a complex world of living creatures that helps us grow healthy plants. This guide to soil teaches readers the basics of this fundamental garden component, including microorganisms, nutrients, and soil health and care. The curriculum-driven text also brings in related subjects such as composting and worms to provide a comprehensive learning experience. The text's elementary science content is conveyed through age-appropriate text, diagrams, colorful photographs, and fact boxes

"Knowledge of the behavior of soil mechanics is essential for forecasting the internal displacements and actions of any construction. This book, although theoretical at first glance, also offers a more practical scope, giving readers adequate tools to plan geotechnical projects correctly."--

In the last decades, in some Mediterranean areas, pedodiversity decreased mainly due to pedotechnique application in large-scale farming that transformed original soils into Anthrosols. Supporting the consideration that soils can be considered as living systems, the original concept of 'soil genetic erosion' is re-proposed. Data, extrapolated and modeled from a Soil Information System in a study case representative of a Mediterranean landscape, predicted that most of the soil types would disappear in few years leading to a decrease of the soil diversity and originating soil genetic erosion. This circumstance is intentionally here told in form of a story where the fairy tale characters are some soils facing extinction in the landscape. Soil genetic erosion could result in a negative impact on the environment because it reduces the soil's security through a drastic reduction of the soil ecosystem services with a decrease of the immaterial benefit for the environment. The conviction that soils, as well as animals and plants, are living bodies, and pedodiversity is equally important as biodiversity in maintaining sustainability and ecosystem services, might truly attract the attention of the public opinion. Besides, focussing more on the soil economic dimension and strengthening the assignation of 'economic value' to the soil ecosystem services, also politicians and administrators could increase their interest in soil security.
