Getting energy from the land and practicing good conservation are not mutually exclusive. A federal ag deartment researcher says we can have both through using biomass.
USDA researcher Doug Karlen, who works at the Agricultural Research Service’s National Soil Tilth Lab in Ames, Iowa, told attendees of the recent USDA Outlook Forum that conservation and energy from biomass can be compatible if three things are considered.
“If we utilize multiple feedstock options, multiple conversion platforms and recognize that’s there’s no single solution.”
Karlen also told the group that you have to consider how land conditions vary. In addition, biomass cannot always be seen as just a waste waiting to be made useful. He points out that the trade-off for using biomass from fields for bioenergy is that there is no residue left over to renew the soil with nutrients, as well as losing the habitat for wildlife those crop leftovers provided. Karlen says that’s why it is so important to have a diversity of biomass products within a certain area.
