In a recent [Permaculture Forum (Upper Midwest)] post there was some
concern about the proposed harvesting of prairie biomass for energy,
suggested by the Minnesota studies of David Tillman's group. According to
their analysis, using a prairie plant mixture of up to 14 species "comes
out 6 to 16 times better than corn grain ethanol or biodeisel [sic] ."

Doesn't harvesting prairie plants for conversion to ethanol result in serious
organic matter and accompanying soil microflora depetion in those soils?
