Miscanthus sinensis is a perennial grass native to Asia, but since its introduction to the United States in the late 19th century, it has become both a major ornamental crop and invasive species. In this case, the energy consumption advantage of the torrefaction chain versus the WWP chain almost doubles to 10,3%. Once the leaves are shed in winter, a suitable habitat is provided for yellowhammers. Vicente-Chandler et al. Mezclado en un 50%-50% con carbón, puede usarse en usinas convencionales de carbón, sin modificaciones. Denmark: Autumn harvest 17. Perennial crops such as Miscanthus and short‐rotation coppice (SRC) willow and poplar have low nitrogen input requirements (with benefits for N2O emissions and water quality), can sequester soil carbon due to reduced tillage and increased belowground biomass allocation, and can be economically viable on marginal and degraded land, thus minimizing competition with other agricultural activities and avoiding iLUC effects (Hudiburg et al., 2015; Carvalho et al., 2017). See page 47. These blends and mixtures can also include woody biomass. measured a napier yield of 75.6 tonnes per hectare per year the second year of growth under heavy fertilisation and with rainfall level 1000 mm annually. Giant miscanthus (Miscanthus x giganteus), an aptly named perennial warm-season grass, grows up to 13 feet tall. ", "Our work shows that crop establishment, yield and harvesting method affect the C. cost of Miscanthus solid fuel which for baled harvesting is 0.4 g CO2 eq. There are many cases where these criteria are satisfied. Austria: Autumn harvest 17–30. Major barriers to the breeding of miscanthus varieties are the high costs involved and the long breeding periods, necessary because most yield- and quality-relevant parameters are not quantifiable until after the establishment phase of 2–3 years. ", "This study distils a large body of literature into simple statements around the environmental costs and benefits of producing Miscanthus in the UK, and while there is scope for further research, particularly around hydrology at a commercial scale, biodiversity in older plantations or higher frequency sampling for N2O in land-use transitions to and from Miscanthus, clear indications of environmental sustainability do emerge. Consideration must be given to appropriateness of plantation size and location, whether there will be enough water to sustain its production and the environmental cost of transportation to end-users; its role as a long-term perennial crop in a landscape of rotational agriculture must be understood so as not to interfere with essential food production. Perennial agricultural systems, such as grassland, have time to replace their infrequent disturbance losses which can result in higher steady-state soil carbon contents (Gelfand et al., 2011; Zenone et al., 2013). [...] The assumption that annual cropland provides greater potential for soil carbon sequestration than grassland appears to be over‐simplistic, but there is an opportunity to improve predictions of soil carbon sequestration potential using information on the initial soil carbon stock as a stronger predictor of ∆C [change in carbon amount] than prior land use. Winter harvest 30. McIsaac et al. There are various boiler manufacturers and suppliers who claim they would be happy to utilise miscanthus in their boilers and will stand over the warranty with its use. There are no stable markets for miscanthus biomass and relevant applications are low-value. The authors found that Miscanthus offered a different ecological niche during each season; most of the frequently occurring species in the winter were woodland birds, whereas no woodland birds were found in the wheat; in summer, however, farmland birds were more numerous. One outstanding quality of this large grass is lending a tropical effect to any landscape. (2013) found Miscanthus energy production (from propagation to final conversion) to offer far higher potential GHG savings per unit land area when compared to other bioenergy systems. Low establishment costs", "Results show that new hybrid seed propagation significantly reduces establishment cost to below £900 ha, "C4 species characteristically demonstrate improved efficiency in nitrogen (N) and water-use [28,29]. ", "Tillage breaks apart soil aggregates which, among other functions, are thought to inhibit soil bacteria, fungi and other microbes from consuming and decomposing SOM (Grandy and Neff 2008). Giant Chinese Silver Grass, Miscanthus Floridulus ‘Giganteus’ This grass is somewhat experimental to see how it does in this climate – so far it looks very well adapted, as it’s fast growing and very tall. These deposits don't just reduce heat exchanger efficiency; they also play a major role in corrosion as these deposits can react with sulphur in the flue gas to form alkali sulphates releasing chlorine. Miscanthus might be a useful game cover crop and nursery for young pheasants and partridges. Miscanthus is also new to farmers and they have neither the knowledge nor the technical equipment to cultivate it. Benefits of a transition to 2G crops include increased farm‐scale biodiversity (Rowe et al., 2011), improved functional attributes such as predation (Rowe et al., 2013) and a net GHG mitigation benefit (Hillier et al., 2009). harvnb error: no target: CITEREFVicente-ChandlerSilvaFigarella1959 (, "The total water requirements are approximately 100 mm (4 inches) per month rainfall equivalent. ", "[...] [E]vidence does indicate that the use of low‐input perennial crops, such as SRC, Miscanthus and switchgrass, can provide significant GHG savings compared to fossil fuel alternatives provided that reasonable yields are obtained, low carbon soils are targeted (see sections 2 and 3 above), and the development context is one where tension with land use for food (and associated potential for iLUC emissions) is mitigated. Studies by Semere and Slater (2007b) have shown biodiversity in miscanthus to be higher than in other crop stands, but still lower than in open field margins. We have Miscanthus Giganteus available for the 2020 growing season. ", "In the combustion of miscanthus, the inorganic constituents remain as ash. The unprocessed Miscanthus has an HGI of zero which essentially implies under the test conditions, that no fuel would reach the desired 75 µm and thus, assuming co-milling, there would be either a greater energy requirement for milling to achieve 75 µm or the pulverised fuel particles would be greater than 75 µm in diameter. The authors used FAO's freely available yield prediction software, "Miscanthus grown on contaminated soils can contain higher shoot TE [trace elements; metals and metalloids] concentrations, but the TF [translocation factor], which is for the most part less than 1, indicates that root-to-shoot TE transfer is minimized (Table 3). Open areas between stools provide ideal habitat for birds such as skylarks and meadow pipits. ", "After centuries of burning wood for energy or processing forage into horse power, the first generation of bioenergy feedstocks were food crops, such as maize, oil seed rape, sugar cane, and oil palm, used to produce bioethanol and biodiesel. Miscanthus giganteus is a large perennial grass, growing 12-14 ft annually. (2009) stated how irrigation in the first 3 years after the establishment affected miscanthus belowground growth and size, and the same authors found good aboveground yields during the fourth and fifth years (around 27 and 18 Mg ha, This yield is a result of a computer simulation, it is not an actual measured yield. A biogas chain with 100% heat utilization and lower transportation distances would perform better. The main use of lignocellulosic biomass from perennial crops is as a solid fuel for heat and power generation—a comparatively low-value use, its profitability being ultimately determined by the price of fossil fuels. ", "Miscanthus can be harvested by cutting with a conditioner mower and baling in large Heston bales or round bales and then chipped out of the bales. Skylarks, meadow pipits and lapwings use miscanthus, as well as 37 other species of birds including wren, linnet and goldfinch that feed on the grass seeds. In: Climate Change and Land: an IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems", https://en.wikipedia.org/w/index.php?title=Miscanthus_x_giganteus&oldid=994491990, Creative Commons Attribution-ShareAlike License. 6, [...] the trendline suggests a net accumulation rate of 1.84 Mg C ha, Given the EU average peak yield of 22 tonnes dry matter per hectare per year (approximately 15 tonnes during spring harvest).

Miscanthus ‘Giganteus’. A high GHG- and fossil-energy-saving potential was also found for domestic heating on account of the short transportation distance. This grass is sterile triploid (three sets of chromosomes) formed by a natural cross of miscanthus sacchariflorus and miscanthus sinensis. Key transitions include; (i) shrinkage, which predominantly represents the decomposition of carbonates in hydrothermally derived chars, (ii) deformation temperature, essentially representing the onset point at which the powdery ash starts to agglomerate and starts to stick to surfaces, (iii) hemisphere, whereby ash is agglomerating and is sticky and (v) flow, whereby the ash melts. In other words, the "[...] K [potassium] release seems to be limited by the quantity of available Cl [chlorine]." Plant solo as an accent or specimen, or plant in masses in borders, cottage-style gardens, and meadows. This handy grass has been used for roof thatching, crafts, and paper products, and more recently, biofuels. Any agricultural production is primarily based on human demand, and there will always be a trade-off between nature and humanity or one benefit and another; however, the literature suggests that Miscanthus can provide a range of benefits while minimizing environmental harm. When soil aggregates are broken open with tillage in the conversion of native ecosystems to agriculture, microbial consumption of SOC and subsequent respiration of CO2 increase dramatically, reducing soil carbon stocks (Grandy and Robertson 2006; Grandy and Neff 2008).". At this point, potassium will instead fuse with silicates and aluminiosilicates at approximately 800 °C, and will be retained in the ash. See, "[...] [M]iscanthus had different chemical properties to that of ordinary wood pellets and requires specific boiler technologies to handle its alternative burning nature [...]. ", "Significant reductions in GHG emissions have been demonstrated in many LCA studies across a range of bioenergy technologies and scales (Thornley et al., 2009, 2015). As more studies began to include assessment of dLUC and iLUC impacts, the credibility of first‐generation bioenergy as an environmentally sustainable, renewable energy source was damaged. Additionally, Smil estimates that newly installed photovoltaic solar parks reaches 7–11 W/m, "Soil carbon stocks are a balance between the soil organic matter decomposition rate and the organic material input each year by vegetation, animal manure, or any other organic input.
