I think that's the point of using biosolids as the soil-enhancing agent..the project was overseen by a member of the National Academy of Science's committee on soil science from the University of Washington..among the findings: lower cost of production, and biosolids-amended soils had higher yields than unamended soils.achieved goal of creating recycling loop of biosolids-to-biodiesel Kendall Christiansen _____ From: Reindl, John [mailto:Reindl@no.address] Sent: Monday, February 04, 2008 2:11 PM To: Kendall Christiansen; GreenYes@no.address Subject: RE: [GreenYes] Compost-to-Switchgrass-to-Fuel? I would hope that the biofuels industry would pay more attention to what the soil scientists are reporting -- that biofuels change the carbon that should be recycled back to the land and instead put it into fuel tanks. At one of the conferences on biofuels that I attended, several soil scientists gave presentations on how the carbon level in soils is declining and that biofuels could make this situation much worse.
