Higher traditional crop prices due to increased demand for corn from the ethanol industry has increased the relative advantage that row crops have over switchgrass. Results indicate that farmers will convert to switchgrass production only with significant conversion subsidies. To examine potential environmental consequences of conversion, we investigate three stylized landscape usage scenarios, one with an entire conversion of a watershed to switchgrass production, a second with the entire watershed planted to continuous corn under a 50% removal rate of the biomass, and a third scenario that places switchgrass on the most erodible land in the watershed and places continuous corn on the least erodible. For each of these illustrative scenarios, the watershed-scale Soil and Water Assessment Tool (SWAT) hydrological model (Arnold et al., 1998; Arnold and Forher, 2005) is used to evaluate the effect of these landscape uses on sediment and nutrient loadings in the Maquoketa Watershed in eastern Iowa. 530 $a Also available via the World Wide Web. 650 0 $a Alcohol as fuel $x Economic aspects $z United States. 650 0 $a Energy crops $x Economic aspects $z United States. 650 0 $a Panicum $x Economic aspects $x Economic aspects $z United States. 700 1 $a Babcock, Bruce A. $q (Bruce Alan) $9 60604 710 2 $a Iowa State University. $b Center for Agricultural and Rural Development. 830 0 $a CARD briefing paper ; $v 07-BP50. $9 59760 856 41 $u http://www.card.iastate.edu/publications/DBS/PDFFiles/07bp50.pdf 941 $a 3 952 $l IAOX771 $d 20240710101325.0 952 $l USUX851 $d 20180703061804.0 952 $l OVUX522 $d 20180104013547.0 956 $a http://locator.silo.lib.ia.us/search.cgi?index_0=id&term_0=BC835424493111E49277FB87DAD10320 994 $a C0 $b IOZInitiate Another SILO Locator Search
