“…The estimations of net returns of growing switchgrass for bioenergy purposes are also highly uncertain. At this time, observed data on large‐scale switchgrass production are not available and estimated biomass production costs vary substantially in the literature . Depending on the assumptions made on biomass price and production cost, estimated economic returns could be quite different.…”

Integrating conservation practices with bioenergy has been recommended as a promising strategy to improve bioeconomy and water quality but the literature on the economics of this strategy is limited. This study evaluated the value proposition of reducing nutrient loss from cropland by implementing switchgrass riparian buffers in the Lower Mississippi River Basin (LMRB). Nutrient loss was simulated by using the Soil and Water Assessment Tool. The value proposition of nutrient abatement was quantified by estimating (1) value of trapped nutrients as fertilizer and (2) potential net returns of harvesting switchgrass as bioenergy feedstock at different farm‐gate prices. Results suggest that switchgrass buffers may reduce mean annual total nitrogen and total phosphorus loads from cropland in the LMRB by 23% and 31%, respectively. The value of trapped nutrients is considerable (mean = $69 ha−1 year−1) but far less than the cost of implementing a switchgrass buffer (mean = $163 ha−1 year−1). At biomass prices of $20, $40, $60, and $80 per dry‐ton, mean net returns of switchgrass buffers (without considering land‐use change from cropland to buffers) were estimated to be around −$66, $199, $463, and $727 ha−1 year−1, respectively. Total net returns for the LMRB may be reduced by 20% if switchgrass is grown without the addition of commercial fertilizer. The results highlight the potential of switchgrass buffers for improving water sustainability of both agricultural and bioenergy production. The value proposition of switchgrass buffers is nevertheless sensitive to future feedstock price. The impact of fertilizer prices change and forgone income on benefit analysis is also presented. © 2018 The Authors.

“…However, because there is presently only one commercially available clone, Miscanthus x giganteus, it has some limitations such as a lack of winter hardiness during the establishment period [21]. Additionally M. x giganteus needs to be propagated vegetatively resulting in high plantation costs [3]. Contrary to this, switchgrass can be established via seeds and the lower production costs make it a more practical option among the energy crops [26].…”

“…Miscanthus produces about 250 percent more ethanol per acre than operations based on existing kernel-corn fields (Heaton, Dohleman, and Long 2008), and it has been estimated that new plantings could entirely replace existing corn-kernel production using 16 percent fewer acres (Mishra, Torn, and Fingerman 2013). It is not as well known or programmatically pushed a species as switchgrass, although in one very recent economic analysis densely planted Miscanthus yielded twice the latter in terms of dollar value per acre, and it can become an economically viable option as an ethanol source at prices that are about 10 percent lower than would be required for switchgrass bioethanol (Bansal et al 2013). Miscanthus is being aggressively targeted for trait improvement as a biofuel , particularly with regards to increasing the width and longevity of canopy growth .…”

With the goal of determining which plant materials-other than the edible portions of crops like corn, small grains, sugar cane, and vegetable oils-were being researched as alternative energy feedstocks, a search was performed on the topic of Biofuels within the Web of Science. An examination of article titles and keywords in the 50 most cited and 250 most recent biofuels articles disclosed 263 pertinent mentions of plants. Underutilized portions of crops already being grown for food or biofuels led, followed by inedible "energy" grasses. Residues from wood processing, inedible plant oils, and aquatic plants were less referenced.
