Switchgrass is a high-yielding perennial grass harvested once during the winter months when the crop has dried down. As a perennial, it is planted once and will regrow year after year. The appeal of this native grass is that it can be densely planted and high yielding while requiring a minimal amount of inputs like fertilizer and weed control once it has been established. Yields will average 6 dry tons per acre per year. Material will be baled at harvest.
Switchgrass does well on lower quality soils, unmanaged pastureland, and fallow fields. It provides not only biomass, but also significant environmental and wildlife benefits as well.
Genera is contracting for both established acres of switchgrass as well as for growers to plant new acres. Initial switchgrass production agreements will be for a 5-year term.
High biomass sorghum is an annual crop that has been derived from grain sorghum to maximize biomass yields. Plants can grow to 15’ in height, and stalk diameter will be comparable to corn. Yields for biomass sorghum will average around 7 dry tons per acre and the crop can be grown on lower quality ag land.
Planting and management of biomass sorghum can be accomplished using existing equipment (standard planters, sprayers, etc). At harvest, the sorghum will be cut with a mower-conditioner or self-propelled windrower and baled. Biomass sorghum is typically harvested in late July through September. While still containing a high moisture content when mowed, sorghum can be dried in the field to below 20% moisture content prior to baling.
Biomass sorghum may provide some great opportunities to add value to under-utilized pasture acres or low productivity cropland.
