Wednesday, 30 June INTRODUCTION

Wednesday 30 June 2004

  • Division into two groups: (1) roots/nutrients and (2) microbial ecology
  • Each group discusses and documents:
    • the indicators to provide
    • the discussion and planning of common experiments
    • proposals for STSMs
  • Presentations of the outcome of each group
  • STSMs, homepage, next workshops
  • Establishment of an AGENDA
  • Closing the WG3 meeting

Minutes of the 1st Meeting WG3 – Tune Landboskole, 28-30 June 04

task 1

Wednesday, 30 June DISCUSSION

Task 1
  • Make more N + P available at the right time (standpoint plant AND soil)

How to intervene

  • Study root development
  • Study root associated microbes
  • Study plant growth and development habit
  • Nutrient allocation and timing

Minutes of the 1st Meeting WG3 – Tune Landboskole, 28-30 June 04

providing indicators

Wednesday, 30 June DISCUSSION

Providing indicators
  • Aboveground (sequential sampling) - biomass, N, P, leaf area, grain and straw measurements at harvest
  • Belowground - top 40cm, biomass, root length, root hairs, architecture, “Bertholdsson test”. (Possible additions - root interactions in mixtures, AMF (mycorrhiza))
  • Soil basic data - extractable P, K, total N, texture, density, pH, loss on ignition, CEC

Minutes of the 1st Meeting WG3 – Tune Landboskole, 28-30 June 04

slide23

Wednesday, 30 June DISCUSSION

Considerations

  • Emphasis on existing experiments, use of common techniques where possible
  • modelling techniques likely to be important
  • use existing data where possible
  • work on mixed and arable systems
  • grain yield is not the only consideration (eg biomass production may be important)
  • emphasise importance of root measurements to breeders and obtaining model varieties

Minutes of the 1st Meeting WG3 – Tune Landboskole, 28-30 June 04

task 2

Wednesday, 30 June DISCUSSION

Task 2

a common activity within wg3

Wednesday, 30 June DISCUSSION

A common activity within WG3

Question: Find varieties that optimise nutrient extraction from soil

We collaborate in:

Root development and physiology

Root – shoot allocation

Microbes colonization and efficiency

Modelling nutrient uptake

We need:

Input from WG6 and WG1 for varieties to study and ongoing field trial sites

Wednesday, 30 June DISCUSSION

STSM

Proposals for STSM

  • Work on one field experiment (to be selected) and partners make a set of measurements of root & soil parameters

Minutes of the 1st Meeting WG3 – Tune Landboskole, 28-30 June 04

homepage

Wednesday, 30 June DISCUSSION

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

Minutes of the 1st Meeting WG3 – Tune Landboskole, 28-30 June 04

possible types of workshops

Wednesday, 30 June DISCUSSION

Possible types of workshops
  • Presentation workshops
  • 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 »)
  • WG meetings, discussion and organising common activities
  • 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.

Minutes of the 1st Meeting WG3 – Tune Landboskole, 28-30 June 04

agenda

Wednesday, 30 June DISCUSSION

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 email-allert for WG3 or a discussion forum
