  1. Regional Feedstock Partnership: 2009 Switchgrass Report Vance Owens South Dakota State University San Antonio, TX 23-24 February 2010 Field trial PIs: D. Bransby (AL), E. Heaton (IA), R. Farris (OK), R. Mitchell (NE), D. Viands (NY), J. Fike (VA),

  2. Establish and perform replicated field trials of diverse herbaceous biomass feedstocks at different locations for assessing potential expansion of these feedstocks as a bioenergy resource Overall Objective

  3. Herbaceous crops information

  4. Assess yield potential and quality parameters of switchgrass grown in different environments using standard agricultural practices Switchgrass objective

  5. Alabama – David Bransby New York – Don Viands Oklahoma – Rodney Farris South Dakota – Vance Owens (sustainability site – Tom Schumacher, Shannon Osborne, Dave Clay, Chang Oh Hong) Virginia – John Fike Iowa – Emily Heaton (added in 2009) Nebraska – Rob Mitchell (added in 2009) Group met in Brookings, SD in September 2009 Switchgrass field trial locations and PIs

  6. Switchgrass Trial Information

  7. Field scale (0.4 to 0.8 ha experimental units) Four replicates across landscape Nitrogen (0, 56, 112 kg ha-1) applied in 2009 to all sites established in 2008 Locally adapted cultivar at each location Experimental Design Planting at Ames, IA – 8 May 2009

  8. Initial soil characteristics utilizing minimum soil data set • Total organic carbon; soil pH; Total N; Bulk density; Soil-test P and K • Yield using standard equipment • Subsamples from plots for chemical characterization (samples are being stored at INL at this point) • Other Data collection

  9. 2009 N application and switchgrass harvest dates

  10. Switchgrass establishment based on frequency method of Vogel and Masters (2001) Spring of year after establishment in NY, OK, SD, VA and year of establishment in IA

  11. Stand frequency determination in South Dakota

  12. Switchgrass response to N at four locations in 2009 Switchgrass root biomass to 100 cm 1.73 Mg ha-1

  13. Average height of switchgrass at harvest at four locations

  14. Nebraska switchgrass yield (2006-09)

  15. Bristol, SD – 5 June 2009 (70 ft boom) Fertilizer application

  16. Switchgrass harvest Ithaca, NY – 22 October 2009 Bristol, SD – 28 October 2009

  17. Switchgrass baling and sampling Bristol, SD – 28 October 2009 Ithaca, NY – 22 October 2009

  18. Establishment • Alabama to replant, Oklahoma planted twice • Weeds • South Dakota and Virginia – thin stands (stand frequency less than 30% year after planting • Weather/field conditions • Economics Challenges thus far

  19. Stand establishment Bristol, SD – 8 October 2009 Virginia – Summer 2008

  20. Weather/field conditions Bristol, SD One of wettest Octobers on record One of warmest Novembers on record N Bristol, SD – 28 October 2009 My version of the “cinnamon role”

  21. Alabama will be replanting trial All other sites will apply treatments and harvest biomass May add another trial in IL 2010 Plans
