It may flop in overly rich soils. In the East, it performs well on shallow and droughty soils. SWITCHGRASS Panicum virgatum L. Plant Symbol = PAVI2 Contributed by: USDA NRCS Plant Materials Program Uses Livestock: Switchgrass is noted for its heavy growth during late spring and early summer. “Witchgrass” switchgrass facts Switchgrass is one of many “energy crops”—plants that can be grown specifically to be harvested and converted into biofuel at a biorefinery. 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. Biomass, Erosion Control & Revegetation, Grasses & Grass-like Species, Uplands & Meadows, Wildlife Habitat & Food Plots Classification: Herbaceous Perennial Bloom Period: June to October Foliage Color: Green Height: Up to 4.5 Ft Minimum Root Depth: 12 in pH: 4.5 – 8.0 Indicator Regions (view map & key): Northcentral & Northeast: FAC Midwest: FAC It would have a high amount of biomass per acre and be able to produce a lot of ethanol. It makes a good substitute for some of the larger Miscanthus cultivars. Switchgrass silage benefitted most from addition of alfalfa, urea and plantain. Forage nutritive value was measured using near-infrared reflectance spectroscopy. Sudangrass Sudangrass averages 11.6 percent crude protein. 0000490378 00000 n It is drought tolerant and grows well on shallow rocky soils. The plant is found growing in black soil prairies, clay prairies, sand prairies, typical savannas, sandy savannas, open woodlands, rocky bluffs, sand dunes, edges of marshes, sandy pannes, banks of rivers and ponds, prairie restorations, areas along railroads, roadsides, ditches, abandoned fields, gravel bars, stream banks, open oak and pine woodlands, shores, riverbanks, and high brackish marshes along maritime forest.
