  1. Production Cost Budgets for Perennial Grass Systems Agro-ecosystem Approach to Sustainable Biofuels Production via the Pyrolysis-Biochar Platform (USDA-NIFA AFRI CAP)

  2. Renewable Fuels Standard

  3. The Grand Vision

  4. Potential Energy Crops Switchgrass Miscanthus Poplar Energy Cane Sweet Sorghum

  5. ‘Liberty’ Switchgrass • Developed by CenUSA researchers with USDA-ARS in Lincoln, Nebraska • Introduced in 2013, with a number of field trials across 10 states • Is a high-yielding switchgrass specifically created from bioenergy use • Target of 6-7 tons of biomass per acre • Lifespan of 10+ years

  6. Miscanthus • Family of perennial grasses native to Africa and southern Asia • Giant Miscanthus is a sterile hybrid that has become a popular choice for bioenergy development • Target of 10-15 tons of biomass per acre • Lifespan of 15-30 years

  7. Pre-Establishment • Cost estimates based on conversion from pasture/hay/unimproved grass land • Basic land preparation is the same for either grass • Field preparation includes brush mowing, disking, and soil finishing • Rough cost are $70 per acre

  8. Pre-Establishment • For both types of grasses, best management practices point to planting the grasses after a crop of soybeans • Followed by a cover crop and/or herbicide application • Biggest concern going into establishment year is weed pressure • Rough cost are $300 per acre, and you have a crop to sell (soybeans)

  9. Establishment Year for Liberty Notes: No fertilizer in establishment year, can harvest half of expected crop (3 tons per acre) in establishment year

  10. Establishment Year for Miscanthus Notes: No harvest in establishment year

  11. Year 2 Costs for Liberty Notes: Full harvest of 6 tons per acre, 10% reseeding

  12. Year 2 Costs for Miscanthus Notes: Can harvest half of expected crop (5 tons per acre).

  13. Year 3+ Costs for Liberty Notes: Full harvest of 6 tons per acre

  14. Year 3+ Costs for Miscanthus Notes: Full harvest of 10 tons per acre

  15. Liberty – Long term Over a 10 year timeframe, the Liberty stand: • Would produce 57 tons of biomass per acre • For a total cost of $1,921.38 • Not including land cost • Breakeven price before land: $33.71 per ton • Given average land charge for improved pasture ($77 per acre), breakeven price with land: $47.22 per ton

  16. Miscanthus – Long term Over a 15 year timeframe, the Miscanthus stand: • Would produce 135 tons of biomass per acre • For a total cost of $5,368.99 • Not including land cost • Breakeven price before land: $39.77 per ton • Given average land charge for improved pasture ($77 per acre), breakeven price with land: $48.33 per ton
