Manage weeds immediately, with mowing and herbicides, when seeding switchgrass grown for biomass. Some weeks after the explosion, three of the main characters fall victim to radiation sickness. [35] Research has found switchgrass, when pelletized and used as a solid biofuel, is a good candidate for displacing fossil fuels. Due to its height, switchgrass can form an effective wind erosion barrier. (Ed.) [19] Given that switchgrass contains approximately 18.8 GJ/ODT of biomass, the energy output-to-input ratio for the crop can be up to 20:1. 6/15: Aquatic Vegetation- Beneficial or Pest? [51] The grass's upright growth pattern places its growing point off the soil surface onto its stem, so leaving 25 cm of stubble is important for regrowth. Switchgrass has been researched as a renewable bioenergy crop since the mid-1980s, because it is a native perennial warm season grass with the ability to produce moderate to high yields on marginal farmlands. More specific recommendations for fertilization are available regionally in North America. Much of North America, especially the prairies of the Midwestern United States, was once prime habitat to vast swaths of native grasses, including switchgrass, indiangrass (Sorghastrum nutans), eastern gamagrass (Tripsacum dactyloides), big bluestem (Andropogon gerardi), little bluestem (Schizachyrium scoparium)[3] and others. Used as a specimen, switchgrass makes an excellent substitute for the non-native Miscanthus. Chemical weed control can be used in the fall prior to establishment, or before or after planting. Their models also suggested that the “human toxicity potential” and “eco-toxicity potential” were substantially greater for the high ethanol fuels (i.e., E85 and ethanol) than for gasoline and E10. Soil erosion, both from wind and water, is of great concern in regions where switchgrass grows. Switchgrass can be used as a feedstock for biomass energy production, as ground cover for soil conservation, and to control erosion, for forages and grazing, as game cover, and as feedstock for biodegradable plastics. Samson, R. et al. Used with permission. 1-13. [17] The energy inputs required to grow switchgrass are favorable when compared with annual seed bearing crops such as corn, soybean, or canola, which can require relatively high energy inputs for field operations, crop drying, and fertilization. Gatton Panic grass is widely naturalised in the tropics. Switchgrass has two distinct forms, or "cytotypes": the lowland cultivars, which tend to produce more biomass, and the upland cultivars, which are generally of more northern origin, more cold-tolerant, and therefore usually preferred in northern areas. This diversity, which presumably reflects evolution and adaptation to new environments as the species spread across the continent, provides a range of valuable traits for breeding programs. PLAY. You may use these photos, so long as you give credit to AquaPlant. Read More. Thermal energy applications for switchgrass appear to be closer to near-term scale-up than cellulosic ethanol for industrial or small-scale applications. 2008. [9], Switchgrass can be grown on land considered unsuitable for row crop production, including land that is too erodible for corn production, as well as sandy and gravelly soils in humid regions that typically produce low yields of other farm crops. 38 pages, "Samson et al., 2008": In regions where the. After aquatic plants die, their decomposition by bacteria and fungi provides food (called “detritus”) for many aquatic invertebrates. Additionally, switchgrass is grown as a drought-resistant ornamental grass in average to wet soils and in full sun to part shade. It is used primarily for soil conservation, forage production, game cover, as an ornamental grass, in phytoremediation 2005. Historically, most switchgrass seedings have been managed for the Conservation Reserve Program in the US. Int J Life Cycle Assess. ). Several key factors can increase the likelihood of success for establishing switchgrass. Others are weeds. The switchgrass ethanol industry energy balance is also considered to be substantially better than that of corn ethanol. The seeds are 3–6 mm long and up to 1.5 mm wide, and are developed from a single-flowered spikelet. Life cycle assessment of switchgrass-derived ethanol as transport fuel. Establishing and Managing Switchgrass as an Energy Crop, Forage and Grazinglands, 2008. This page was last edited on 3 December 2020, at 16:11. Its distribution spans south of latitude 55°N from Saskatchewan to Nova Scotia, south over most of the United States east of the Rocky Mountains, and further south into Mexico. Developing Energy Crops for Thermal Applications: Optimizing Fuel Quality, Energy Security and GHG Mitigation. 0.5g/50 Perennial borders, wild gardens, native plant gardens, prairies, meadows or naturalized areas. It is also slightly salt tolerant, withstands occasional flooding, and can be planted near black walnut trees. Springer Science, Berlin, Germany. When harvesting switchgrass for hay, the first cutting occurs at the late boot stage – around mid-June. [40] Life cycle analysis was used to make this assessment. This plant is resistant to deer grazing, drought, erosion, and air pollution. canted. Illustration courtesy of University of Florida/IFAS Center for Aquatic and Invasive Plants. See Important Quotations Explained Summary. Switchgrass is useful for soil conservation and amendment, particularly in the United States and Canada, where switchgrass is endemic. [52], Switchgrass is well known among wildlife conservationists as good forage and habitat for upland game bird species, such as pheasant, quail, grouse, and wild turkey, and song birds, with its plentiful small seeds and tall cover. Forest plants of the southeast and their wildlife uses. A somewhat similar species is Dichanthelium boreale (Northern Panic Grass), which is usually found in open ground and is overall smaller, with narrower leaves (up to ~½ inch), spikelets only about 2 mm long and the lower glume ¼ to 1/3 as long as the spikelet. The grass is tied around the head in order to bring relief from a headache [332 ]. It is now being considered for use in several bioenergy conversion processes, including cellulosic ethanol production, biogas, and direct combustion for thermal energy applications. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil. Used with permission. "Since that mention in the 2006, investment in switch grass has exploded, thanks in large part, experts say, to the President's speech. However, this will depend on whether the cost of constructing and operating cellulosic ethanol plants can be reduced considerably. Panic grass starts out tightly bundles then relaxes outward. A Tale of Three Foxtails. The crop can be established both by no-till and conventional tillage. 2018. [20] Thus, switchgrass cellulosic ethanol should give a higher yield of ethanol per hectare at lower cost. [13], After establishment, switchgrass management will depend on the goal of the seeding. Once established, a switchgrass stand can survive for ten years or longer. The PLANTS Database (http://plants.usda.gov, 28 March 2018). Control Weeds in Switchgrass (Panicum Virgatum L.) Grown for Biomass. [10] [50] Switchgrass becomes stemmy and unpalatable as it matures, but during the target grazing period, it is a favorable forage with a relative feed value (RFV) of 90-104. Both upland and lowland cultivars are deeply rooted (> 1.8 m, in favorable soils) and have short rhizomes. Science. Packing or firming the soil both before and after seeding. It can grow and even thrive in many weather conditions, lengths of growing seasons, soil types, and land conditions. [28] In contrast, corn ethanol yields about 1.28 units of energy per unit of energy input. Livestock and wildlife graze on beaked panic grass from early spring to late fall but should be deferred during the summer to improve plant vigor and density. Photo by Green Deane. In George W. Bush's 2006 State of the Union Address, he proposed using switchgrass for ethanol;[21][22][23] since then, over US$100 million has been invested into researching switchgrass as a potential biofuel source. Panicum grasses can be used to make brooms; bend the grass about 60 cm from the tip, and allow to dry out by hanging for about two weeks. This Agfact describes the species useful for livestock production and the most effective ways of using them. By returning switchgrass and other perennial prairie grasses as an agricultural crop, many marginal soils may benefit from increased levels of organic material, permeability, and fertility, due to the grass's deep root system. Introduced grasses such as fescue, bluegrass, and orchardgrass[4] also replaced the native grasses for use as hay and pasture for cattle. Researchers are continuing to learn more about the specific conditions under which switchgrass causes harm to these species, but until more is discovered, it is recommended switchgrass not be fed to them. Beaked panic grass is also commonly used for erosion control in … Biomass resources options: Creating a BIOHEAT supply for the Canadian greenhouse industry. Pasture type and use: Perennial grass, producing main growth in spring, summer and autumn. [1] Its flowers have a well-developed panicle, often up to 60 cm long, and it bears a good crop of seeds. [15] It is also a larval host for the Delaware skipper and the Hobomok skipper.[16]. Switchgrass can be harvested with the same field equipment used for hay production, and it is well-suited to baling or bulk field harvesting. Bailey Stamler, S., R. Samson and C. Ho Lem. talismanic. Grows 3-6′ tall with coarse stems growing from a dense crown of thick, short, bulbous rhizomes. [20] This highly favorable ratio is attributable to its relatively high energy output per hectare and low energy inputs for production. Accent, group or mass. Introduced perennial warm season bunch grass. Cut it back to the ground in late winter to early spring to maintain an attractive shape. Hiroshima Chapter 4: "Panic Grass and Feverfew". Volume Switchgrass as a Bioenergy Crop, ATTRA - National Sustainable Agricultural Information Service, 2006. The deep fibrous root systems of switchgrass left a deep rich layer of organic matter in the soils of the Midwest, making those mollisol soils some of the most productive in the world. 5/18: Water Quality for Fisheries Management. It can grow up to 2.7 m (8 ft 10 in) high, but is typically shorter than big bluestem grass or indiangrass. [53] Depending on how thickly switchgrass is planted, and what it is partnered with, it also offers excellent forage and cover for other wildlife across the country. With phonetic transcriptions, dictionarie tell you about the pronunciation of words, because the spelling of an English word does not tell you how you should pronounce it. Both glumes are present and well developed. Commons’s Panic-grass and other species of Dichanthelium, a technical manual must be used. [3], Switchgrass is a versatile and adaptable plant. Bai, Y., Luo, L, & van der Voe, E. (2010). When seeded as part of a diverse mixture, planting guidelines for warm-season grass mixtures for conservation plantings should be followed. Combustion studies have been undertaken and it appears to be well-suited as a commercial boiler fuel. In Biofuels, Solar and Wind as Renewable Energy Systems: Benefits and Risks. Upland switchgrass types are generally shorter (≤ 2.4 m, tall) and less coarse than lowland types. Panic grass is a warm weather crop. The plant is said to be diuretic, laxative and preventitive [269, 332 ]. Once established, switchgrass can take up to three years to reach its full production potential. Farrell, A.E. Switchgrass is an excellent forage for cattle; however, it has shown toxicity in horses, sheep, and goats[47][48][49] through chemical compounds known as saponins, which cause photosensitivity and liver damage in these animals. [18] Another study found that switchgrass uses 0.8 GJ/ODT of fossil energy compared to grain corn's 2.9 GJ/ODT. [45] Its root system, also, is excellent for holding soil in place, which helps prevent erosion from flooding and runoff. panicum bulbosum Native to the arid Southwest, including Texas, but adapted to gardens throughout the South. [19] As a greenhouse gas mitigation strategy, switchgrass pellets were found to be an effective means to use farmland to mitigate greenhouse gases on the order of 7.6-13 tonnes of CO2 per hectare. The lower part of the stems has large nodes and internodes with branches coming from the nodes. James H. Miller and Karl V. Miller. Generally, the crop requires modest application of nitrogen fertilizer, as it is not a heavy feeder. Panicum (panicgrass) is a large genus of about 450 species of grasses native throughout the tropical regions of the world, with a few species extending into the northern temperate zone. [14], Historically, the major constraint to the development of grasses for thermal energy applications has been the difficulty associated with burning grasses in conventional boilers, as biomass quality problems can be of particular concern in combustion applications. [11] Plantings that appear to have failed due to weed infestations are often wrongly assessed, as the failure is often more apparent than real. Alternate Names. A summary of switchgrass yields across 13 research trial sites in the United States found the top two cultivars in each trial to yield 9.4 to 22.9 t/ha, with an average yield of 14.6 ODT/ha. Increased attention is being placed on switchgrass management as an energy crop. This plant is used as a dune stabilizer along the southern NC coast. Volume 2. amphibians, reptiles, ducks, etc.). Grazing. 2007. Switchgrass is one of the dominant species of the central North American tallgrass prairie and can be found in remnant prairies, in native grass pastures, and naturalized along roadsides. Use switchgrass in meadows or native plant gardens, or place it in a row for a feathery screen or hedge. They took into account air and water emissions associated with growing, managing, processing and storing the switchgrass crop. Regional guidelines for growing and managing switchgrass for bioenergy or conservation plantings are available. ", "Switchgrass: Native American Powerhouse? (2010) conducted a study to analyze the environmental sustainability of using switchgrass plant material as a feedstock for ethanol production. It is a fibrous rooted annual summer grass that has a zigzag growth pattern. Other common names for switchgrass include tall panic grass, Wobsqua grass, blackbent, tall prairiegrass, wild redtop, thatchgrass, and Virginia switchgrass. Uses Megamax® 049 panic grass is an excellent option for high input, intensive grazing or hay cutting operations. [6], Switchgrass is a diverse species, with striking differences between plants. [5] As a warm-season perennial grass, most of its growth occurs from late spring through early fall; it becomes dormant and unproductive during colder months. Andrew_Wallace49TEACHER. Actually we all do — rice, wheat, oats, barley — but my local trail nibble is Guinea Grass, a relative to millet. Click for a hub of Extension resources related to the current COVID-19 situation. There are three common species of panic grass in North America. Click on the buttons to learn more about each species. One study cites it takes from 0.97 to 1.34 GJ to produce 1 tonne of switchgrass, compared with 1.99 to 2.66 GJ to produce 1 tonne of corn. Switchgrass is both a perennial and self-seeding crop, which means farmers do not have to plant and reseed after annual harvesting. Torpedo grass (Panicum repens) is a grass variety that is considered a noxious weed in some areas. It is a clumping grass and spreads by rhizomes. [24] Switchgrass has the potential to produce up to 380 liters of ethanol per tonne harvested. Also effective as a screen. Below is the phonetic transcription of panic grass: Submerged portions of all aquatic plants provide habitats for many micro and macro invertebrates. Pros and Cons of Panic Grass Submerged portions of all aquatic plants provide habitats for many micro and macro invertebrates. Panicum virgatum, commonly known as switchgrass, is a perennial warm season bunchgrass native to North America, where it occurs naturally from 55°N latitude in Canada southwards into the United States and Mexico. Wildlife: Deer will graze beaked panicgrass. Bai et al. For cattle, however, it can be fed as hay, or grazed. Switchgrass is one of the dominant species of the central North American tallgrass prairie and can be found in remnant prairies, in native grass pastures, and naturalized along roadsides. Grazing switchgrass calls for watchful management practices to ensure survival of the stand. Stands of switchgrass should be harvested no more than twice per year, and one cutting often provides as much biomass as two. It includes information on: There are 21 known species, both introduced and native. Wang, M., Wu, M., & Huo, H. Life-cycle energy and greenhouse gas emission impacts of different corn ethanol plant types. Uses. ... a cost-effective method to control broadleaf weeds is to apply 2,4-D at 1 to 2 quarts per acre * after grass seedlings have tillered and have about four leaves. [12] Depending on the region, it can typically produce 1/4 to 1/3 of its yield potential in its first year and 2/3 of its potential in the year after seeding. Projections in the early 1990s for commercialization of cellulosic ethanol by the year 2000[31] have not been met. They compared efficiency of E10, E85, and ethanol with gasoline. Roger Samson (Online reprint), USDA Studies Switchgrass for Ethanol and Energy Production, Switchgrass as an Alternative Energy crop, "Switchgrass for Bioethanol and Other Value-Added Applications: A Review", "Grass Makes Better Ethanol than Corn Does", https://en.wikipedia.org/w/index.php?title=Panicum_virgatum&oldid=992116810, Native grasses of the Great Plains region, Articles with dead external links from March 2011, Creative Commons Attribution-ShareAlike License. Typical nitrogen (N) content of senescent material in the fall is 0.5% N. Fertilizer nitrogen applications of about 5 kg N/hectare (ha) applied for each tonne of biomass removed is a general guideline. [17] However, these yields were recorded on small plot trials, and commercial field sites could be expected to be at least 20% lower than these results. [26] In contrast, corn ethanol yields about 400 liters per tonne.[27]. Panic grasses are widespread in New South Wales. Fall harvested grasses likely have more application for larger commercial and industrial boilers. Contributed by: USDA NRCS East Texas Plant Materials Center. The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin alphabet. It is effective as an accent plant in a native or water garden. Venture capitalists have poured over $100 million into private companies that are exploring the technology necessary to convert switchgrass into fuel, and large publicly owned companies are also directing their research dollars into biofuels.". The reductions in global warming potential by using E10 and E85 were 5 and 65%, respectively. ©Ted Bodner. Lowland cultivars may grow to ≥ 2.7 m, in favorable environments. [2] Unlike corn, switchgrass can grow on marginal lands and requires relatively modest levels of chemical fertilizers. Leaves abundant, 7-12″ long and flat with a heavy midrib on the lower side. Panic grass definition is - any of various grasses (Panicum and related genera) including some important forage and cereal grasses. beaked panicum, spreading panicum. Some highway departments (for example, KDOT) have used switchgrass in their seed mixes when re-establishing growth along roadways. [8], Switchgrass’ suitability for cultivation in the Gran Chaco is being studied by Argentina's Instituto Nacional de Tecnología Agropecuaria (INTA). This should allow for a second cutting in mid-August, leaving enough regrowth to survive the winter. It turned out to be a revolutionary finding. They have been selected to provide a mix of different plant sizes and growing conditions. 15 (15), 468-477. It can be used by cattle farmers for hay and pasture and as a substitute for wheat straw in many applications, including livestock bedding, straw bale housing, and as a substrate for growing mushrooms. Panicum maximum and then some. Panicum sonorum. These technical problems now appear to have been largely resolved through crop management practices such as fall mowing and spring harvesting that allow for leaching to occur, which leads to fewer aerosol-forming compounds (such as K and Cl) and N in the grass. Ethanol Can Contribute to Energy and Environmental Goals. Prevent erosion by planting en masse on slopes and ridges. Sap from the crushed fresh plant is used as a cicatrisant on wounds and sores [332 ]. Gatton is a highly palatable plant with good forage quality when green. Considerable effort is being expended in developing switchgrass as a cellulosic ethanol crop in the USA. Weeds should be mowed just above the height of the growing switchgrass. Mass plant this grass in the back of a border, or use as a screen. National Plant Data Team, Greensboro, NC 27401-4901 USA. It is ideal in borders where it provides texture, color and contrast. In some warm humid southern zones, such as Alabama, it has the ability to produce up to 25 oven-dry tonnes per hectare (ODT/ha). It is used primarily for soil conservation, forage production, game cover, as an ornamental grass, in phytoremediation projects, fiber, electricity, heat production, for biosequestration of atmospheric carbon dioxide, and more recently as a biomass crop for ethanol and butanol. Herbicides are not often used on switchgrass after the seeding year, as the crop is generally quite competitive with weeds. Generally speaking, the direct firing of switchgrass for thermal applications can provide the highest net energy gain and energy output-to-input ratio of all switchgrass bioconversion processes. Page 1 Page 2 The bomb had not only left the underground organs of the plants intact; it had stimulated them. In contrast, switchgrass cellulosic ethanol and corn ethanol were found to mitigate 5.2 and 1.5 tonnes of CO2 per hectare, respectively. Switchgrass is a hardy, deep-rooted, perennial rhizomatous grass that begins growth in late spring. Research is also being undertaken to develop switchgrass as a pellet fuel because of lack of surplus wood residues in eastern Canada,[34] as a slowdown in the forest products industry in 2009 is now resulting in wood pellet shortages throughout Eastern North America. [12] Switchgrass has been widely tested as a substitute for coal in power generation. Panicum flower in the summer either with tiny inflorescences or silky tassels. Livestock: Beaked panicgrass is grazed by cattle and is of good value for grazing. The … They also factored in the transportation of the stored switchgrass to the ethanol plant where they assumed the distance was 20 km. Moderately palatable, shade-tolerant, moderate drought resistance. No single method of establishing switchgrass can be suggested for all situations. In the United States, switchgrass yields appear to be highest in warm humid regions with long growing seasons such as the US Southeast and lowest in the dry short season areas of the Northern Great Plains. If its biology is properly taken into consideration, switchgrass can offer great potential as an energy crop.[10][14]. I eat grass. [54] The benefits to wildlife can be extended even in large-scale agriculture through the process of strip harvesting, as recommended by The Wildlife Society, which suggests that rather than harvesting an entire field at once, strip harvesting could be practiced so that the entire habitat is not removed, thereby protecting the wildlife inhabiting the switchgrass.[55].
