Leopold Center for Sustainable Agriculture

Biochar and Organic Tomatoes

November 2012

Applying carbon-rich biochar to farmland improves soil health, but questions still remain about how biochar will influence yields and interact with mycorrhizae, important soil fungi. Erich Sneller, ISU Environmental Sciences student, describes an experiment at TableTop Farm that applies biochar, with or without mycorrhizae, to organic tomatoes. This experiment is part of a larger effort to study biochar in natural ecosystems. Filmed September 2012.
