“…In previous studies in SD, the mean yield of different prairie cordgrass populations was 8.3 Mg ha -1 [9] while average yield of "Red River" and "Atkins" prairie cordgrass in Kansas was 9.5 Mg ha -1 [11]. We observed yields lower than, similar to, or higher than these at the four locations used in this study (Fig.…”

“…Prairie cordgrass is a facultative wetland species, predominantly found in low floodplains and wetlands [13] where it occupies soils too wet and inadequately aerated for other species such as big bluestem (Andropogon gerardii Vitman) and switchgrass [12]. Studies have documented its potential for biomass production in short-season areas in Europe [14], southwestern Quebec [15], eastern South Dakota [9], and Kansas [11]. On agricultural soils in Minnesota, prairie cordgrass had consistently greater long-term yields than miscanthus (Miscanthus × giganteus), switchgrass, or big bluestem [16].…”

Optimizing nitrogen (N) management is an important factor for sustainable perennial biomass systems. However, N application is costly, both financially and environmentally. Our objectives were to determine: (1) N rate and plant spacing effects on yield and yield components of prairie cordgrass swards and (2) fertilizer N replacement value (FNRV) of kura clover in prairie cordgrass-kura clover binary mixtures. Plots were established in Illinois, Minnesota, South Dakota, and Wisconsin, USA, in 2010. Kura clover was transplanted on 30-cm centers in all treatments in which it was a component; prairie cordgrass seedlings were transplanted within the kura clover on 60- and 90-cm centers. Monoculture prairie cordgrass stands were established at the same population densities of mixed stands and fertilized with 0, 75, 150, or 225 kg N ha-1. Biomass was harvested in the autumn from 2011 to 2013. N (urea), year, plant spacing, and year × plant spacing affected prairie cordgrass production at all locations. Prairie cordgrass yield increased with N application, but the response varied by location. N application tended to increase prairie cordgrass tiller density and consistently increased tiller mass. Prairie cordgrass yield with 0 N was equal to or less than the yield of prairie cordgrass/kura clover mixtures at all locations in 2011 and 2012; however, kura clover provided a FNRV of 25–82 kg N ha-1 to prairie cordgrass in 2013. Kura clover has potential to provide N to prairie cordgrass in binary mixtures of these two species and on land that may not be easily farmed due to wetness.

“…[77] Higher lignin yield (up to 80 %) could be obtained from prairie cordgrass (PCG) and switchgrass (SWG). [78] Generally speaking, there is still much room for development in the fractionation of lignocellulosic biomass and the extraction of lignin using DESs. Homogeneous molecular weight lignin could be obtained using DESs including benzyltrimethylammonium chloride (BTMAC)/lactic acid (LA) in a short time (2 h) at 140°C.…”

Biomass Fractionation and Lignin Fractionation towards Lignin Valorization

Lignin, as the most abundant aromatic biopolymer in nature, has attracted great attention due to the complexity and richness of its functional groups for value‐added applications. The yield of production of lignin and the reactivity of prepared lignin are very important to guarantee the study and development of lignin‐based chemicals and materials. Various fractionation techniques have been developed to obtain high yield and relatively high‐purity lignin as well as carbohydrates (hemicelluloses and celluloses) and to reduce the condensed and degraded nature of conventional biorefinery lignin. Herein, novel and efficient biomass fractionation and lignin fractionation towards lignin valorization are summarized and discussed.

Intercropping kura clover (Trifolium ambiguum) (KC) with prairie cordgrass (Spartina pectinata) (PCG) has great potential for biofuel feedstock on marginal lands. This study evaluated the impacts of 10‐year PCG‐KC intercropping and PCG monoculture fertilized with different nitrogen (N) rates of granular urea (five treatments: PCG‐KC, PCG‐0N, PCG‐75N, PCG‐150N, and PCG‐225N) on soil biogeochemical properties: (i) in the surface soil (0‐ to 10‐cm depth) at three different sampling times during the crop growing season: spring (April, pre‐emergence), summer (June, active growth), and fall (November, post‐harvest); and (ii) at different soil depths (0–5, 5–15, 15–30, 30–45, and 45–60 cm) (only total carbon (C) and N) in fall 2021. All soil biogeochemical parameters were higher during summer as compared to spring and/or fall, except urease activity, ammonium‐N, microbial biomass C and N, and fluorescein diacetate (FDA). On average over the sampling times, PCG‐KC had significantly higher β‐glucosidase activity and hot‐water extractable organic N than PCG‐0N; but no significant difference between PCG‐KC and N‐fertilized PCG. Cold‐water extractable organic N was significantly lower than the highest N rate, but not significantly different from PCG‐0N and lower N rate treatments. Urease activity under PCG‐KC treatment was double that of PCG‐0N and PCG‐75N; FDA was higher in PCG‐KC than all monocultures. No treatment effect was found on soil total C and N, except that they decreased with depth. Overall, intercropping PCG‐KC showed some benefits in terms of promoting soil biogeochemical properties during crop growth periods, having lower residual reactive N in the soil, and maintaining biomass yield and quality on marginal lands.
