University of Iowa Planting Miscanthus Demonstration Plot

05 May 2014

A 13-acre pilot field of Giant Miscanthus (Miscanthus x giganteus clone IL) will be planted Wednesday, May 7 at a field is just outside of Iowa City (south on Highway 1, 0.5 miles from Menards; map).

In 2013, the University of Iowa (UI) planted a 16-acre pilot Miscanthus field in Muscatine County. The UI has contracted with Repreve Renewables to supply the rhizomes and plant the 2014 field, which, along with the 2013 field, will used to better understand growing Miscanthus in southeast Iowa, as well as demonstrate planting and harvesting techniques to potential growers. The UI is planning to plant an additional 2,500 acres of Miscanthus by 2016 to produce up to 25,000 tons per year of biomass fuel.

Miscanthus is large, warm-season, perennial grass used for energy, bedding and building material. It is one of a portfolio of dedicated energy crops suitable for Iowa, and can produce large amounts of renewable energy while providing all the environmental benefits associated with perennial grasses. The crop is sterile and must be planted with rhizomes or small plants (‘plugs’).

As part of the Biomass Fuel Project, ISU is collaborating closely with UI to develop cropping systems and management for the Biomass Fuel Project.

University of Iowa Biomass Fuel Project

The UI has a sustainability goal to procure 40 percent of its energy from renewable sources by 2020. Biomass is cofired (mixed) with coal and burned in boilers, reducing the University’s fossil fuel usage.

Biomass from dedicated energy crops (miscanthus, switchgrass), timber stand improvement projects, opportunity wood (storm damage, emerald ash borer, etc.), and organic industrial byproducts (oat hulls, paper sludge, etc.) are being developed as part of the renewable fuel portfolio.
