We evaluated the biogeochemical cycling and relative greenhouse gas (GHG) mitigation potential of proposed biofuel feedstock crops by modeling growth dynamics of Miscanthus 9 giganteus Greef et Deuter (miscanthus), Panicum virgatum L. (switch-grass), Zea mays L. (corn), and a mixed prairie community under identical field conditions. DAY-CENT model(More)
The C4 perennial grasses Miscanthus × giganteus and Panicum virgatum (switchgrass) are emerging bioenergy crops. They are attractive because they are productive and recycle nutrients to the overwintering belowground rhizomes, before the dry shoots are harvested. They are therefore expected to require minimal fertilizer inputs, a desirable trait for any(More)
Traditional energy sources in Illinois include coal, oil, and nuclear power. There is presently, however, much interest in locally produced energy sources that can reduce reliance on energy that originates outside of Illinois. Wind, corn-based ethanol, and soybean-based biodiesel are all examples of locally produced alternative energy sources. Other(More)
Highlights • Giant Miscanthus (Miscanthus x giganteus) is a warm-season Asian grass showing great potential as a biomass crop in Illinois; at several Illinois sites, research plantings of Giant Miscanthus have produced greater yields than switchgrass. • Giant Miscanthus is sterile and is propagated by rhizome division. • To grow Giant Miscanthus, plant(More)
Poor first winter survival in Miscanthus × giganteus has been anecdotally attributed to incomplete first autumn senescence, but these assessments never paired first-year with older M. × giganteus in side-by-side trials to separate the effect of weather from stand age. Here CO2 assimilation rate (A), photosystem II efficiency (ΦPSII), and leaf N(More)
