Short-rotation intensive culture for the production of energy feedstocks in the US: A review of experimental results and remaining obstacles to commercialization

Potential Soil Carbon Sequestration and CO2Offset by Dedicated Energy Crops in the USA

“…These management options are similar or the same as those typically applied in SRWC energy plantations with shorter harvesting cycles (e.g., Perlack et al, 1986;Hansen, 1993;Grigal and Berguson, 1998;Ulzen-Appiah et al, 2000;Adegbidi et al, 2001;Riemenschneider et al, 2001;Eaton, 2003). Findings related to forest management studies are a valuable basis for discussion and comparison to studies designed specifically for energy cropping in the U.S.A. Because of the positive growth responses to such long-term treatments, these practices are currently being considered by some researchers as a model for SRWC plantations for fiber and fuel production in the Southeast (Coleman et al, 2004).…”

“…a From Perlack et al (1986), Eaton (2003), and Coleman et al (2004). b The C 4 photosynthetic pathway (generally found in warm-season grasses) compared to the C 3 pathway (in cool-season species) differs in that C 4 photosynthesis: 1) can occur at higher temperatures, 2) operates at lower CO 2 concentrations, and 3) exhibits greater water use efficiency.…”

Biofuels: Putting Current Practices in Perspective

“…This island nation ranks 20th in the world in terms of per capita carbon dioxide emissions (5), and it serves as an ideal case study to demonstrate the potential of using cellulosic wastes to supply a city's energy demands and reduce its GHG emissions. Singapore's urban areas are home to about 1 million planted trees, which produce 50,000 to 156,000 tons of horticultural waste biomass (tree trunks, twigs, and leaves) each year (6). A recent study estimates that each ton of woody biomass feedstock can produce 288 to 371 liters of cellulosic ethanol (7).…”

Generalized Allometric Regression to Estimate Biomass of Populus in Short-rotation Coppice

“…Poplar species and their hybrids have been one of the most studied forest trees in short-rotation coppice. The expected annual production of poplar short rotation should be about 12-15 tonnes of dry matter per hectare (Perlack et al 1986, Auclair & Bouvarel 1992, Bouvet & Berthelot 1994, Hinckley 1997.…”
