Actual stover removal rates 03/20/2013 @ 2:39pm I work for POET-DSM Advanced Biofuels, which is building its first commercial cellulosic ethanol plant right now in Iowa. I just wanted to note that these removal rates are very far beyond what POET-DSM contracts with farmers. We contract for 1 ton of biomass per acre on average, which is 20-25% of the above-ground biomass in that area (vs taking more than half the stover as this research did). We have commissioned the U.S. Department of Agriculture and Iowa State University to conduct soil sustainability work for the last 5 years on our fields, and we share that data with the public. http://www.poet.com/resources/documents/IowaStateUniversity_Emmetsburg%20Soil%20Study_Report2011.pdf That research has demonstrated that at the lower removal rate, there are no erosion concerns. There is some minor nutrient replacement. This research is more a warning to those looking to strip the fields.
