“…In the scenario analysis, perennial grasses were planted on May 15, 1992, and harvested on November 15th of each year to maximize biomass potential (Griffith et al, 2014;Hudiburg et al, 2015). The annual biomass sorghum was planted on June 1st and harvested on October 31st of each year (Hao et al, 2014) (Table S1).…”

Hydrological responses of land use change from cotton (Gossypium hirsutum L.) to cellulosic bioenergy crops in the Southern High Plains of Texas,USA

The Southern High Plains (SHP) region of Texas in the United States, where cotton is grown in a vast acreage, has the potential to grow cellulosic bioenergy crops such as perennial grasses and biomass sorghum (Sorghum bicolor). Evaluation of hydrological responses and biofuel production potential of hypothetical land use change from cotton (Gossypium hirsutum L.) to cellulosic bioenergy crops enables better understanding of the associated key agroecosystem processes and provides for the feasibility assessment of the targeted land use change in the SHP. The Soil and Water Assessment Tool (SWAT) was used to assess the impacts of replacing cotton with perennial Alamo switchgrass (Panicum virgatum L.), Miscanthus 9 giganteus (Miscanthus sinensis Anderss. [Poaceae]), big bluestem (Andropogon gerardii) and annual biomass sorghum on water balances, water use efficiency and biofuel production potential in the Double Mountain Fork Brazos watershed. Under perennial grass scenarios, the average (1994-2009) annual surface runoff from the entire watershed decreased by 6-8% relative to the baseline cotton scenario. In contrast, surface runoff increased by about 5% under the biomass sorghum scenario. Perennial grass land use change scenarios suggested an increase in average annual percolation within a range of 3-22% and maintenance of a higher soil water content during August to April compared to the baseline cotton scenario. About 19.1, 11.1, 3.2 and 8.8 Mg ha À1 of biomass could potentially be produced if cotton area in the watershed would hypothetically be replaced by Miscanthus, switchgrass, big bluestem and biomass sorghum, respectively. Finally, Miscanthus and switchgrass were found to be ideal bioenergy crops for the dryland and irrigated systems, respectively, in the study watershed due to their higher water use efficiency, better water conservation effects, greater biomass and biofuel production potential, and minimum crop management requirements.

“…The high biomass production potential of switchgrass with low inputs makes it an excellent choice as a sustainable bioenergy crop (Sharma et al 2003;Sadeghpour et al 2014). In addition, switchgrass has a large root system and adapts to a wide range of ecosystems as well as marginal lands (Calles Torrez et al 2013;Hardin et al 2013;Griffith et al 2014;Sarkar et al 2014). It has been reported that switchgrass has the ability to accumulate some heavy metals.…”

Morph‐physiological responses of two switchgrass (Panicum virgatum L.) cultivars to cadmium stress

et al. 2016

Two cultivars of switchgrass, ‘Alamo’ (lowland type) and ‘Cave‐in‐Rock’ (upland type), were used to examine the morph‐physiological responses of plants to different cadmium (Cd) levels under hydroponic condition treated with 0, 10, 20 and 40 μmol L−1 CdCl2 for 2 weeks. The main results showed that both seedlings of ‘Alamo’ and ‘Cave‐in‐Rock’ can survive even in 40 μmol L−1 CdCl2 treatment. However, the growth of the two cultivars was significantly (at least P < 0.05) inhibited by Cd stress. The plant biomass, water content, photosynthetic pigments content, total root length (RL), root surface area (RA), root volume (RV) and number of root tips of two tested cultivars were significantly decreased after treatment with Cd. ‘Alamo’ showed higher capability of Cd translocation from root to shoot than ‘Cave‐in‐Rock’, but ‘Cave‐in‐Rock’ had higher capability of Cd uptake and accumulation than ‘Alamo’. ‘Cave‐in‐Rock’ accumulated higher Cd in root than ‘Alamo’, the root average diameter, RL, RA and RV at the root segment in 0.3–0.9 mm diameter in ‘Cave‐in‐Rock’ were dramatically higher than those of ‘Alamo’, which indicates that a well‐developed root system may contribute to higher Cd accumulation in ‘Cave‐in‐Rock’. Above all, both ‘Alamo’ and ‘Cave‐in‐Rock’ could be cultivated in Cd polluted area. At the same time, they have bioremediation function, especially, this function of seedling in ‘Cave‐in‐Rock’ should be greater than ‘Alamo’, since the amount of Cd absorption and accumulation in ‘Cave‐in‐Rock’ was significant higher than ‘Alamo’.

The objective of this study was to examine the hydrothermal liquefaction of sugarcane bagasse using ethanol and black liquor (BL) in a pilot scale. Combinations of co-solvents (ethanol/ water, ethanol/BL) were studied at various concentrations and reaction conditions. The maximum oil yield of 61% was achieved with a reaction temperature of 300 °C for 30 min and using pure BL as a solvent, while the highest higher heating value (HHV) was obtained from a 50:50 ethanol-BL mixture. The oils contained alcohols, esters, phenolic compounds, aromatics, and heterocyclics. The O/C and H/C ratios of the oil were comparable with traditional biodiesel and commercial diesel. Although this study showed there are some improvements to be made to improve the chemical composition, the approach has potential for large-scale production of a substitute for fossil-fuel-based diesel.
