Biofuels will help meet rising demands for energy and, ideally, limit climate change associated with carbon losses from the biosphere to atmosphere. Biofuel management must therefore maximize energy production and maintain ecosystem carbon stocks. Increasingly, there is interest in intercropping biofuels with other crops, partly because biofuel production on arable land might reduce availability and increase the price of food. One intercropping approach involves growing biofuel grasses in… Expand
Microbial nitrogen cycling response to forest-based bioenergy production.
TLDR
Findings indicate soil N cycling and availability has increased in pine beds of the pine-switchgrass treatment compared to those of thepine-native treatment, potentially alleviating any negative effects of N competition between pine and switchgrass. Expand

Concern over rising atmospheric CO2 due to fossil fuel combustion has intensified research into carbon-neutral energy and fuel production. Therefore, bioenergy production has expanded during the lastExpand
Indications of shifting microbial communities associated with growing biomass crops on marginal lands in Southern Ontario
Purpose-grown biomass is derived from herbaceous species such as switchgrass ( Panicum virgatum ), and miscanthus ( Miscanthus giganteus ) as well as woody species such as poplar ( Populus spp.) andExpand
The Influence of Switchgrass Establishment on Soil Organic Matter Pools in an Agricultural Landscape
Agricultural activities have significant impacts on global biogeochemical cycles, particularly carbon and nitrogen. Conventional row-crop agriculture accelerates the decomposition of soil organicExpand
Impacts on soil nitrogen availability of converting managed pine plantation into switchgrass monoculture for bioenergy.
TLDR
Investigation of the conversion of previously managed loblolly pine stand into SWITCH in eastern North Carolina, U.S.A. indicated that establishment of SWITCH on poorly drained lands previously under PINE is less likely to significantly impact total soil N availability and potentially has minimum N leaching losses since soil mineral N under this system will be dominated by ammonium-N.

Perennial Grass Bioenergy Cropping on Wet Marginal Land: Impacts on Soil Properties, Soil Organic Carbon, and Biomass During Initial Establishment
The control of soil moisture, vegetation type, and prior land use on soil health parameters of perennial grass cropping systems on marginal lands is not well known. A fallow wetness-prone marginalExpand
Impacts of forest-based bioenergy feedstock production on soil nitrogen cycling
Abstract We investigated impacts of simultaneous production of biomass for biofuel and quality timber on soil nitrogen (N) cycling in a poorly drained forest soil of eastern North Carolina, U.S.A.Expand
Soil and Aggregate-Associated Carbon in a Young Loblolly Pine Plantation: Influence of Bioenergy Intercropping
ABSTRACT In order to assess the carbon (C) footprint of forest-based bioenergy systems, it is necessary to quantify soil C storage. This study addressed effects of intercropping loblolly pine (PinusExpand
Capacity of biochar application and nitrogen fertilization to mitigate grass competition upon tree seedlings during stand regeneration.
TLDR
Competitive relationships amongst these species were altered by soil amendment-induced fertility, which suggests its competitive ability is increased on nitrogen-rich or fertilized sites. Expand
Biofuel Benefit or Bummer? A Review Comparing Environmental Effects, Economics, and Feasibility of North American Native Perennial Grass and Traditional Annual Row Crops When Used for Biofuel
While biofuels have been touted as a benefit for growers—with the ability to be planted on marginal lands, for improved wildlife habitat, to sustain soils, and to reduce runoff—there remains to be aExpand
