Common-Site Yield Studies

Bryce Stokes

Senior Advisor

DOE Golden Field Office

  • Goal of Presentation:

  • Provide background and preliminary description of the concept

  • Initiate discussion among the teams

  • Start process of thinking about “how to make it work” -- leverage resources among ourselves and outside partners


Background and goals
Background and Goals

Background

  • Rational, scientific approach to provide quality data and to extent our research resources

  • Discussion point during program review

  • Need expressed by experts at herbaceous and woody crops high-yield scenario workshops

    Goals

  • Complement current Regional Partnership yield studies

  • Not “comparative yield studies,” but “comprehensive yield studies” for improved management options/decisions in landscape and feedstock diversity implementation

  • More systematic approach to modeling and validating America’s feedstock potential of energy crops with multiple options

  • Garner opportunity to enhance partnership


Barriers and opportunities

Barriers

Land – larger area: up to 20 ac per crop currently

Logistics – “gaggle” of PI’s, equipment, cultural practices, etc.

Experimental design – trees/crops mixed

Research issues – site control, data access, publications, etc

No additional Funds in FY10 or FY11?

Opportunities

Add smaller side plots to current sites

New small, test plot design

Potential in future large-scale studies

Similar cultural practices to build on

Use variety of research mgt models – multiple PIs or single PI with protocols

Extend current resources

Garner support and new partners

What s next
What’s Next?

  • At this time, nothing formal

  • Sufficient interest at DOE-HQ to promote informally for now and hopefully integrate into future programming and budgets

  • Encourage informal discussions and even collaboration as possible

  • If needed, provide mechanisms for planning and facilitating collaboration
