This publication contains the proceedings of the Brazilian Agricultural Research Corporation (EMBRAPA)/FAO International Technical Workshop on Biological Management of Soil Ecosystems for Sustainable Agriculture, which was held at EMBRAPA-Soybean headquarters in Londrina, Brazil, from 24 to 27 June 2002. The report includes a review of current understanding and knowledge of the biological management of soil ecosystems through a set of case studies from different production systems and socio-economic conditions, in the areas of indicators and assessment of soil health, adaptive management and innovative technologies. A general discussion and review of lessons learned leading to the main recommendations and further steps for the implementation of an International Soil Biodiversity Initiative are also presented. The financial support was provided through the agricultural biodiversity component of the FAO-Netherlands Partnership Programme.

It is becoming more relevant to explore soil biological processes in terms of their contribution to soil fertility. This book presents a comprehensive scientific overview of the components and processes that underpin the biological characteristics of soil fertility. It highlights the enormous diversity of life in soil and the resulting effects that management of land can have on the contribution of this diverse community to soil fertility in an agricultural context.

Global agriculture is now at the crossroads. The Green Revolution of the last century is losing momentum. Rates of growth in food production are now declining, with land and water resources becoming scarcer, while world population continues to grow. We need to continue to identify and share the knowledge that will support successful and sustainable

Plant-parasitic nematodes are one of multiple causes of soil-related sub-optimal crop performance. This book integrates soil health and sustainable agriculture with nematode ecology and suppressive services provided by the soil food web to provide holistic solutions. Biological control is an important component of all nematode management programmes, and with a particular focus on integrated soil biology management, this book describes tools available to farmers to enhance the activity of natural enemies, and utilize soil biological processes to reduce losses from nematodes.

Taking a sustainable approach, this volume explores the various soil management techniques. It begins with an overview of the elementary concepts of soil management and then delves into new research and novel soil management tools and techniques. Topics include: • Clays as a critical component in sustainable agriculture with respect to carbon sequestration in conjunction with its interaction with soil enzymes • The potential utilization of microbes to mitigate crop stress • Resource conservation technologies and prospective carbon management strategies • The use of smart tools for monitoring soils • Effective nutrient management approaches • Nanotechnological interventions for soil management • Techniques for the remediation of soils contaminated by metals and pesticides
