Researching the Effects of Biochar on Urban Trees

Arborists in Chicago are studying the results of biochar on trees growing in urban soils that are typically hostile to trees. This research is part of a larger urban-soils study that includes applications of biochar in greenhouse and field plot settings at The Morton Arboretum. The Bartlett Tree Research Laboratories have also been testing adding biochar to the soil mix when planting trees. More information and media coverage of this study about biochar and urban tree care can be found on the Bartlett Tree Experts web site.
