  1. The Regional Feedstock Partnership: Herbaceous Energy Crops and CRP Land for Biomass Production Across Environmental GradientsCRP Management Joe Castro, University of Illinois Species lead: D.K. Lee University of Illinois at Urbana-Champaign PIs: E. Aberle (ND), K. Harmoney (KS), C. Chen (MT) C. Jordan (GA), R. Kallenbach (MO), G. Kakani (OK)

  2. U.S. Conservation Reserve Program (CRP) The CRP program encourages farmers to convert highly erodible cropland or other environmentally sensitive acreage to vegetative cover. A cost-share and rental payment program under the USDA Reduce soil erosion, enhance water supplies, improve water quality. Increase wildlife habitat, and reduce damages caused by floods and other natural disasters Native grasses, wildlife planting, trees, filter strips

  3. U.S. CRP- Current Status Source: USDA FSA • Current enrollment (Jan. 2010): 31.19 mil. ac • Change in enrollment since 2007: down 5.58 mil.ac • Major resource change (2007 to 2010) • Existing grasses and legumes: 15.3 to 11.6 mil. ac • New native grasses: 7.2 to 6.2 mil. ac • New introduced grasses and legumes: 3.4 to 2.5 mil. ac • Permanent wildlife habitat: 2.6 to 2.0 mil. ac • Expiration schedule • 2009: 3.9 mil. ac • 2010: 4.5 mil. ac • 2011: 4.4 mil. ac • 2012: 6.5 mil. ac

  4. Objective • Assessing potential of CRP land as a sustainable bioenergy feedstock resource • Replicated field trials • Relatively large experimental unit (about 0.5 ha) • Effects of N fertilization and Harvest timing on biomass yield and species composition changes Montana, June 27, 2009
