Agricultural Biomass Sources
Biomass is a raw material that is renewable and an alternative to conventional energy sources. The revolutionary concept behind agricultural biomass is its availability is allied to the agricultural products we have produced and depended on for decades. Critics claim utilizing agricultural biomass will deplete our food supply but this biomass is actually the residual excess from the rural yield or above ground non-grain portion of crops. Agricultural biomass such as: corn stover, sorghum straw and wheat straw have potential in contributing to bioenergy and bioproducts in the near future.
Barley Straw: The above-ground plant material remaining after the barley grain is harvested, including leaves and stalks but not the roots of the plant. Barley (Hordeum L.) is an annual cereal plant that produces edible grain. Barley has an average residue ratio of 1.2 and an average bushel weight of 48lbs.
Corn stover: The above-ground plant material remaining after the corn grain is harvested, including leaves and stalks but not the roots of the plant. Corn (Zea mays L.), also known as Indian corn or maize, is an annual cereal plant grown in North America that produces edible grain. Corn has an average residue ratio of 1 and an average bushel weight of 70lbs.
Oat Straw: The above-ground plant material remaining after the oat grain is harvested, including leaves and stalks but not the roots of the plant. Oat (Avena L.) is an annual cereal plant that produces edible grain. Oat has an average residue ratio of 1.3 and an average bushel weight of 32lbs.
Sorghum Straw: The above-ground plant material remaining after the sorghum grain is harvested, including leaves and stalks but not the roots of the plant. Sorghum (Sorghum bicolor L.) is an annual cereal plant that produces edible grain. Barley has an average residue ratio of 1.4 and an average bushel weight of 56lbs.
Wheat Straw: The above-ground plant material remaining after the wheat grain is harvested, including leaves and stalks but not the roots of the plant. Wheat (Triticum aestivum L.) is an annual cereal plant that produces edible grain. Wheat has an average residue ratio of 1.5 and an average bushel weight of 60lbs. Some wheat crops are harvested in the winter and have a slightly higher residue ratio. Winter wheat has an average residue ratio of 1.7.
