  1. Biochar and Low Organic Matter Soils Duane Friend Extension Educator

  2. Acknowledgements • Funding for the study was through the Illinois Department of Agriculture Sustainable Ag Grant program • Additional assistance has been provided by the Illinois Sustainable Technology Center

  3. Field Study Details • Plots at 3 field sites with low inherent soil organic matter • Three replications of 0, 10 and 20 tons/acre (0, 24.7 tons/Ha, 49.4 tons/Ha) of biochar applied in 10 foot by 10 foot (305 by 305 cm) plots at each site • Each site planted to field corn, with normal agronomic operations • Examined soil changes, yield

  4. McCully Heritage (Calhoun County) • Site had been in alfalfa • Was plowed, with biochar then applied and tilled in • Site was hand seeded with Roundup Ready corn

  5. Central Illinois Irrigated Growers plot (Mason County) • Plot previously in field corn • Plot irrigated • Planted with Roundup Ready corn by farm operator

  6. Site M (Jim Edgar Conservation Area- Cass County) • Plot previously in soybeans • Plot part of strip till field • Planted to non Roundup Ready corn, by farm operator
