Additionally, after a killing frost, the multidirectional arrangement of the switchgrass in the windrow was easier to bale than the linearly arranged windrow left by a sickle-bar head. Áì(Å,ÒfwÙ¾`A$X%GX¤ D² ³Á²Ö`[6HÎ|é»,¢ Farm-scale production cost of switchgrass for biomass. Grassland scientists have conducted research on switchgrass (Panicum virgatum) for more than 70 years, with initial research focusing on livestock and conservation. Switchgrass as a Bioenergy Crop. Generally, lowland plants have a later heading date and are taller with larger and thicker stems. Jones, and R.L. Each big round bale (Photo 4) represents 50 gallons of ethanol assuming 80 gallons per ton of switchgrass, with a farm gate cost of $0.75/gallon at $60/ton. Biomass and Bioenergy 32:18-21. 2001. Switchgrass (Panicum virgatum) is a native warm-season grass that is a leading biomass crop in the United States. 48:2159-2164. Illinois USA, Nebraska 28, Pathfinder, and Sunbur st) on associated weed growth. Large square bales can spoil from the top and bottom and can lose more than 25% of total dry matter in six months when stored outside in the open (top left), but covering the large square bales with hay tarps (top right) reduces dry matter loss to about 7% in six months. N rate and row spacing effect on C partitioning, Yield and quality parameters for 20 strains, Long-term yield under different management regimes, Fike et al., 2006a 1#/ac provides 3 seeds/ft2. Photo: Rob Mitchell. Implementing switchgrass-based bioenergy production systems will require converting marginal land from annual row crops to switchgrass and could exceed 10% in some regions depending on the yield potential of the switchgrass strains (Table 3). Switchgrass - Nebraska 28 (per pound) $11.00 / bag Switchgrass - Nebraska 28 (per pound) How much seed would you like to purchase? Phosphorus (P) recommendations for the western corn belt based on two common soil test levels (Anderson and Shapiro, 1990). This research from nearly 50 production environments indicates that growing switchgrass for cellulosic ethanol is economically feasible in the central and northern Great Plains. Successful stand establishment during the seeding year is mandatory for economically viable switchgrass bioenergy production systems (Perrin et al., 2008). 2008. This is really important to you! Grasses and legumes for cellulosic bioenergy. Switchgrass seed is naked, very small with about 325,000 to nearly 400,000 easy to drill seeds per pound. Herbaceous perennial energy crops may be used in conjunction with agriculture residues (corn stover and wheat straw), which likely would be harvested in autumn, and perennial grasses could be harvested in very early spring while they are dry, similar to when prairies are typically burned. De La Torre Ugarte, C.T. There is considerable variation in plant type. 2005. Liebig, M.A., M.R. 2002. Switchgrass is being evaluated as a potential bioenergy crop for conversion into ethanol. Most plot and field-scale switchgrass research has been conducted on forage-type cultivars selected for other livestock-based characteristics in addition to yield. Chromosome numbers of cultivars of switchgrass (Panicum virgatum L.), indiangrass (Sorghastrum nutans L.) and the tall bluestem complex of big bluestem (Andropogon gerardi Vitman.) Recommended P levels for the western corn belt are in Table 1. Brummer, K.J. Indiangrass cultivars âNebraska 54â, âOtoâ, âOsageâ, and âHoltâ were all tetraploids (2n = 40). However, seed viability was not significantly (P 0.05) different for the cultivated varieties of switchgrass and Northern populations; but was significantly lower for Southern Iowa populations in 2002. There are potential difficulties with large-scale switchgrass monocultures, but most are speculation at this point. Fertilizing grass pastures and haylands. 1998. The biology and agronomy of switchgrass for biofuels. âNebraska 28â Cultivar plant materials is a low growing plant from Nebraska and developed for â¦ West Virginia 40° 179 Summer upland Tetraploid South Nebraska 41° 114 Sunburst upland ? Weed competition is the major reason for switchgrass stand failure. A stable and consistent feedstock supply must be available year-round to the ethanol or power plant. In a study conducted on 12 farms in Nebraska, South Dakota, and North Dakota, switchgrass fields with a stand frequency of 40% or greater provided a successful stand (Schmer et al., 2006). It is most commonly found in prairie lowlands, but will grow under wide range of climatic conditions. Farrell, A.E., R.J. Plevin, B.T. 2005. Switchgrass is a native warm-season grass that has been used for hay, forage, and conservation purposes for decades and switchgrass research in Nebraska has been ongoing since 1936. Weed control is essential during establishment but with good management is typically not required again. Examples of grass cultivars developed by this procedure include 'Blackwell' and 'Nebraska 28' switchgrass (Hanson 1972). Assuming 25 miles is the maximum economically feasible distance feedstock can be transported, all of the feedstock must be grown within a 25-mile radius of the bio-refinery, an area containing about 1.26 million acres. Wolf. Table 1. Vogel, K.P., and R.B. Excellent results are obtained by planting after a soybean (Glycine max) crop using a properly calibrated no-till drill with depth bands that plant seeds 0.25 inch to 0.5 inch deep followed by press wheels (Figure 2). 2015-41595-24254 from the USDA National Institute of Food and Agriculture. Applying 8 oz of quinclorac plus 1 qt of atrazine per acre immediately after planting has provided effective grassy and broadleaf weed control for establishment. Results of a recent economic study based on the five-year average of 10 farms in Nebraska, South Dakota, and North Dakota indicated producers can grow switchgrass at a farm gate cost of $60/ton (Perrin et al., 2008). Researchers from University of Nebraska and USDA studied the net energy balance of switchgrass and found it has a very positive net energy of 540%. 2004. Thus, yield data comparing forage-type upland cultivars like Cave-In-Rock, Shawnee, Summer, and Trailblazer do not capture the full yield potential of switchgrass and are not fair comparisons. Reed. Switchgrass varieties for western Nevada. Schmer, M.R., K.P. Switchgrass is adapted to much of North America. of Nebraska-Lincoln Extension, IANR NebGuide G78-406-A. However, they noted that SOC increases varied across sites, and the variation in SOC change reiterated the importance of long-term environmental monitoring sites in major agro-ecoregions. Fales, eds. Nitrogen (N) fertilizer is not recommended during the planting year since N will encourage weed growth, increase competition for establishing seedlings, increase establishment cost, and increase economic risk associated with establishment if stands should fail (Mitchell et al., 2008). Kimble. 129 0 obj
There must be an available land base in the local agricultural landscape to produce feedstock. In the Great Plains and Midwest, maximum first-cut yields are attained by harvesting switchgrass when panicles are fully emerged to the post-anthesis stage (~1 August). Harvesting after switchgrass senescence in autumn but while cool-season grasses are growing, then applying glyphosate at 1 to 2 qt acre-1, is an effective method to reduce cool-season grasses. Switchgrass - Nebraska 28 (per pound) $11.00 / bag (943.0bags available) Switchgrass - Nebraska 28 (per pound). Removing 50% of the corn stover each year reduced subsequent corn grain yield, stover yield, and total biomass. and sand bluestem (Andropogon hallii Hack.) Vogel, R.B. Nebraska 28 (NE 28) was adapted in Nebraska, and performs well in sandy, well drained soils throughout the upper Midwest. Owens, and J.J. Doolittle. Sufficient regrowth may occur about one year out of four to warrant a second harvest after a killing frost. Perennial herbaceous energy crops provide several challenges. Cultivars such as Blackwell and Nebraska 28 were released in this manner. Round bales tend to have less storage losses than large square bales (>800 lb) when stored outside, but square bales tend to be easier to handle and load a truck for transport without road width restrictions (Figure 5). 2008. Concerns arise for potential disease and insect pests, and the escape of switchgrass as an invasive species with the production of millions of switchgrass acres, especially since little research has been conducted on these topics. In most agricultural fields, adequate levels of phosphorus (P) and potassium (K) will be in the soil profile. 3 Table 1. Impact of row spacing, nitrogen rate, and time on carbon portioning of switchgrass. 98:1518-1528. 20:1-27.
