269 Biochar Use for Improving Environmental Quality: I

Oral Session
A05 Environmental Quality
Adding biochar to soils has been shown to increase crop yields for tropical soils. It is anticipated to do the same for temperate regions. Amending soils with biochar may improve soil quality because biochar can act as a liming agent, reduce bulk density, and improve soil nutrient status. Soil properties and processes influenced by biochar addition will be explored.
