Wednesday, 30 June DISCUSSION

29 Minutes of the 1st Meeting WG3 – Tune Landboskole, June 04 STSM Proposals for STSM Work on one field experiment (to be selected) and partners make a set of measurements of root & soil parameters Wednesday, 30 June DISCUSSION

30 Minutes of the 1st Meeting WG3 – Tune Landboskole, June 04 Homepage What to put on the homepage: minutes of WG3 meetings method list of blackboard a presentation of each participant in WG3 (short description of each p., publication list, working topic etc)..pdf files as reprints of publications upon request to the author responsible for WG3: Matthias Lutz Wednesday, 30 June DISCUSSION

31 Minutes of the 1st Meeting WG3 – Tune Landboskole, June 04 Possible types of workshops 1.Presentation workshops 2.Practical workshop learning and seeing new methods, do something together (learning by doing) evalutation of field tests etc. data discussion (refer to as « digging workshop ») 3.WG meetings, discussion and organising common activities 4.Mixtures Important is the way to organise a « presentation workshop », as a basis of discussion, it might not be necessary to show «perfect presentations » but to present methodology and results which allows questions and suggestions. Wednesday, 30 June DISCUSSION

32 Minutes of the 1st Meeting WG3 – Tune Landboskole, June 04 AGENDA Meeting at Witzenhausen to refine our discussions WG meeting: spring 2005 in Switzerland –« Contributions to genotype testing » –evtl. combined WG3 + WG5 workshop –evtl. postpone to do a practical workshop (digging) Establish -allert for WG3 or a discussion forum Wednesday, 30 June DISCUSSION

33 Minutes of the 1st Meeting WG3 – Tune Landboskole, June 04 Thanks a lot for the excellent discussions! Wednesday, 30 June
