Mitchell, R.N. In 1986, the Story County Conservation Board, the Department of Forestry at ISU, the Iowa DNR-Forestry Division and the Iowa National Heritage Foundation established a cooperative demonstration of growing wood for energy at Hickory Grove County Park in Colo, Iowa. Energy produced from renewable carbon sources is held to a different standard than energy produced from fossil fuels, in that renewable fuels must have highly positive energy values and low greenhouse gas emissions. Aside from those already mentioned, switchgrass is a perennial grass and is an easily established and maintained renewable resource. The U.S. Department of Energy (DOE) Bioenergy Feedstock Development Program selected switchgrass as the herbaceous model species for biomass energy. Most plot and field-scale switchgrass research has been conducted on forage-type cultivars selected for other livestock-based characteristics in addition to yield. Producing switchgrass pellets for use in decentralized home heating systems is well developed, and pellet stoves are briskly selling to individual homeowners as supplemental heating sources. • High yields – Switchgrass grown for forage can produce up to twice as much as tall fescue on an acre of land. Assuming 25 miles is the maximum economically feasible distance feedstock can be transported, all of the feedstock must be grown within a 25-mile radius of the bio-refinery, an area containing about 1.26 million acres. These modeled results were validated with actual inputs from multi-farm, field-scale research to predict energy output. Brummer, K.J. Vogel, and G. Sarath. Most of the general public first heard about switchgrass on January 31, 2006, when President George W. Bush in his State of the Union Address said, “We must also change how we power our automobiles. The capital investment requirements for both of these systems would be in excess of $4 per gallon of annual capacity. of Nebraska-Lincoln. Skip to Main Content However, make certain switchgrass is dormant when glyphosate is applied, or stands could be damaged. In addition to storage losses in weight, there can be significant reductions in biomass quality, and the biomass may not be in acceptable condition for a biorefinery. Mitchell, R.B. It was estimated that if established costs were pro-rated over nine production years, cost was reduced an additional $6/ton including land costs. Managing and enhancing switchgrass as a bioenergy feedstock. Hanson, J.D., and H. A. Johnson. Varvel, G.E., K.P. Mitchell, R.B., and B.E. An economic model, "Costs of Producing Switchgrass for Biomass in Southern Iowa," was published by Iowa State University. Partially Funded by USDA Rural Development. In: W.F. Acceptable switchgrass production can be delayed by one or more years by weed competition and poor stand establishment (Schmer et al., 2006). Agron. © 2020 Ag Marketing Resource Center. 2006. Sustainable biomass energy crops must be productive, protective of soil and water resources, and profitable for the producer. Sanderson, M.A., P.R. Adler, A.A. Boateng, M.D. Consequently, the forage-type cultivars in the Great Plains and Midwest are entirely represented by upland ecotypes which are inherently lower yielding than lowland ecotypes. Green Jr., M. Rasnake, and J. Reynolds. Fike. Additionally, switchgrass is well suited to co-generation fuel mixes where other biomass material or municipal wastes are used as additional fuel sources. There are four main cultivar types: southern lowland, southern upland, northern lowland and northern upland. In late May, producers Tony Brannon and Andy Holt planted 5-acre test plots of EG 1101 and EG 1102, switchgrass varieties from Ceres, Inc., a California-based developer and marketer of switchgrass and high-biomass sorghum. Prairie Lands also provides technical assistance for establishing and managing switchgrass stands; current information on product developments; opportunities to participate in new markets; regular updates about the Chariton Valley Biomass Project; and opportunities to participate in demonstrations and research activities. In comparison, wood has been reasoned as producing 19.8 GJ per MT and wheat straw at 19 GJ per MT. The switchgrass was pelletized for easier handling. Moore, N.E. More than 70 years of experience with switchgrass as a hay and forage crop suggest switchgrass will be productive and sustainable on rain-fed marginal land east of the 100th meridian. An ethanol plant requires a reliable and consistent feedstock supply. Switchgrass grows 3 to 10 feet tall, typically as a bunchgrass, but the short rhizomes can form a sod over time. N rate and row spacing effect on C partitioning, Yield and quality parameters for 20 strains, Long-term yield under different management regimes, Fike et al., 2006a
