Much of the initial biofuel development has focused on the use of surplus grain based commodities and has generated concerns about impacts of grain production for fuel. There are many advantages of using grain: the crops are energy dense, there is an existing grain handling infrastructure, farmers and their advisors have experience with these crops and traditional crop subsidies are greatly reduced. As production of these crops for energy expand, the use of reduced tillage, winter cover crops, lower pesticide rates, varieties designed specifically for energy production and alternative grain crop species will need to continue to increase. This presentation will discuss examples of these management strategies being evaluated at Penn State.
