| In the United States, biomass is the largest source of renewable energy accounting for over 3 percent of the energy consumed domestically and is currently the only source for liquid, renewable, transportation fuels. Continued development of biomass as a renewable energy source is being driven in large part by the Energy Independence and Security Act of 2007, which mandates that by 2022 at least 36 billion gallons of fuel ethanol be produced, with at least 16 billion gallons being derived from cellulose, hemi-cellulose, or lignin. However, the market for cellulosic biofuels is still under development. As such, little is known about producer response to feedstock prices paid for dedicated energy crops. While there have been some studies done on factors that... |

| Switchgrass, a warm-season perennial grass, native to the region, has received considerable interest for its potential role as a dedicated feedstock for cellulosic-based bio-fuels. This research examined the farm-gate price needed for switchgrass to provide per-acre net returns equal to those obtained from traditional crops in south central North Dakota. Future production costs for switchgrass and net returns from traditional crops were estimated for three soil productivity classes and also were developed to reflect the historical revenue and cost patterns associated with producers who are typically more or less profitable (i.e., average net return per acre) than regional averages. Prices were calculated using an annualized equivalent analysis of... |

| Analysis of the potential to supply 25% of projected 2025 U.S. transportation fuels indicates sufficient biomass resources are available to meet increased demand while simultaneously meeting food, feed, and export needs. Corn and soybeans continue to be important feedstocks for ethanol and biodiesel production, but cellulose feedstocks (agricultural crop residues, energy crops such as switchgrass, and forestry residues) will play a major role. Farm income increases, mostly because of higher crop prices. Increased crop prices increase the cost of producing biofuels. |

| Arkansas cropping pattern changes at the county level were estimated under various scenarios involving a likely decline in water availability, the development of a biomass market for renewable energy production, and the potential of a widely used carbon offset market. These scenarios are analyzed separately and jointly to determine which of the three scenarios is expected to have the largest impact on net (emissions – sequestration) greenhouse gas (GHG) emissions, renewable fuels feedstock supply, and producer net returns. Land use choices included conventional crops of rice, cotton, soybean, corn, grain sorghum, pasture, and hay. Specialty crops of loblolly pine and switchgrass were modeled for their respective potential to sequester carbon and provide... |

| As the hunt for renewable energy sources from agriculture intensifies, many agricultural producers are contemplating what crops to grow in the foreseeable future. On the one hand, there are traditional food crops, such as soybean, corn, and wheat, which have recently enjoyed a spike in prices, primarily because of the seemingly ever-growing demands of the corn to ethanol industry. On the other hand, there are the lesser-known perennial energy crops, such as switchgrass. Although much information on various aspects of switchgrass production exists, this paper discusses the adaptation of existing production and processing information to Arkansas conditions as a potential alternative to crop production. |

| There is limited information available explaining the agronomic and economic relationships between yield and nitrogen and phosphorus applications to growing switchgrass produced in phosphorus-deficient soils. The objective of this study was to determine the effects of nitrogen and phosphorus fertilizers on feedstock yield and measures of expected total cost, gross revenue, net return, and breakeven price of feedstock produced in phosphorus-deficient soils in the southern Great Plains. Data were collected from a three-year, two-location agronomic field study conducted in south-central Oklahoma. Two discrete nitrogen treatments (0 and 134 kg ha-1) and four discrete phosphorus treatments (0, 30, 60 and 90 kg ha-1) were randomly assigned to small plots... |
