Christian Valentin and Mike Kirkby

The number of people attending the sessions was 26-40 (average 31). There was a wide ranging discussion which will, it is hoped, lead to more collaboration between the areas of soil erosion, soil organic matter and soil biology. Provisional plans were made to hold a follow-up meeting to explore possible areas of active joint research, in approximately two years time. The Editor of the Journal Agricultural Ecosystems and Environment (Martin Carter) has been informally approached about publishing a special issue based on the presentations, and most presenters have indicated a willingness to take part in this publication. A provisional manuscript deadline has been set for March ’00, with probable publication in Jun-Aug ’01.
