Abstract:
... The deployment of dedicated energy crops and the related land-use change are topical issues, particularly in relation to carbon storage and climate change mitigation effects. In order to maximize their mitigation potential and to fully supply new biorefineries, perennial energy crops may be established, not only on former idle and grazing lands, but also on the least remunerative cropland, as indi ...

Abstract:
... Switchgrass (Panicum virgatum L.) is a native perennial grass identified as a promising biofuel crop for production on marginal agricultural lands. As such, research into switchgrass fertility and the switchgrass rhizosphere microbiome has been ongoing in an effort to increase production sustainability. We examined the effects of cultivar and phosphorus (P) fertilization on biomass yield, P remova ...

Abstract:
... Large scale industrial biomass efforts, whether in pursuit of cellulosic bioethanol, or combustion, will require amounts of feedstock in excess of available crop residues, leading to considerations of purpose grown agricultural biomass. This study determines the yields and break-even prices of perennial grass biomass crops in the state of North Dakota using bioeconomic GIS-based simulation modelli ...

Abstract:
... Switchgrass (Panicum virgatum L.) is a native, perennial C₄ grass found across North America that was first used as a forage for grazing livestock and, later, as food and shelter for wildlife and for soil conservation. More recently, breeding efforts have focused on utilizing switchgrass as an herbaceous energy crop (HEC). In June 2017, a rusty brown powdery spore mass was observed to be associate ...

Abstract:
... In order to develop sustainable biomass production, bioenergy crops should have both high biomass productivity and good combustion quality. In this study, we investigated the effects of different N fertilization rates (0, 100, 150, and 200 kg ha–¹y–¹) and harvest times (autumn and winter) on the chemical compositions of 4 promising bioenergy crops (miscanthus, switchgrass, giant reed, and bulbous ...

Abstract:
... Perennial grasses can assimilate nitrogen (N) fixed by non-nodulating bacteria living in the rhizosphere and the plant's own tissues, but many details of associative N fixation (ANF) remain unknown, including ANF's contribution to grass N nutrition, the exact location of fixation, and composition of the associated microbial community. We examined ANF in switchgrass (Panicum virgatum L.), a North A ...

Abstract:
... Switchgrass (Panicum virgatum) is a perennial grass highly valued as an energy crop resource for the production of bioethanol due to its high carbohydrate content, fast growth, and ability to grow in lands that cannot support crop or food production. In the present study, this biomass was submitted to steam explosion pretreatment in a semi-continuous pre-pilot reactor with the aim of obtaining a p ...

Abstract:
... Global expansion of high-input annual grain crops and associated nitrogen (N) fertilizer use can have negative consequences for the environment and human health. Nitrate nitrogen (NO₃-N) leaching from fertilized annual crops can contaminate groundwater and pollute natural aquatic ecosystems and rural drinking water sources. Intermediate wheatgrass (IWG; Thinopyrum intermedium) is a perennial grass ...

Abstract:
... Advanced biofuel production requires feedstock with specific composition in terms of quantity and quality. Decisions about the harvest time of perennial energy grasses have important implications for bioconversion process as well as for the life-span of the plant stand. Four-year data from long term-field trials were used to identify the optimal crop-specific harvest date (autumn vs. winter), in r ...
