The System Performance team focuses on providing detailed analyzes of feedstock production options. The team also creates models to assist policymakers, farmers, and the bioenergy industry to make informed decisions about which bioenergy feedstocks to grow, where to produce them, what environmental impacts they will have, and how biomass production systems are likely to respond to and contribute to climate change or other environmental shifts.
Our System Performance team members have produced an extensive resource library with material for everyone interested perennial grasses and their role in the larger landscape.

System Performance team research shows water quality benefits when biofuels are produced from perennial grasses; provides guidance for policymakers, farmers, and the bioenergy industry.
- AgSolver, an Iowa-based company, helps producers shift to perennial grass production using software tools that assess crop potential and profitability.
- Keri Jacobs (Economics, Iowa State University explains that farmers value the conservation and environmental benefits of switchgrass grown for biofuels but also consider profit, alternative land uses, and public policy incentives when making production decisions.
- Virginia L. Jin (Research Soil Scientist, USDA-Agricultural Research Service) explains how residue management and tillage can reduce greenhouse gas emissions from soils during production of corn stover for biofuel.
- William F. Lazarus (Professor & Extension Economist, University of Minnesota) explains the use of this nitrogen reduction planting tool.
The Economics of Switchgrass for Biofuel (Jul. 2014)
- William F. Lazarus (Professor & Extension Economist, University of Minnesota) explains that the profitable production of switchgrass for biofuel today depends primarily on the price of oil, as well as the Renewable Fuel Standard (RFS).
