There has been much anecdotal evidence about the effects of aerated compost teas on soil, but there have been few peer-reviewed studies on the topic. In this episode of Science of Arboriculture, Dr. Bryant Scharenbroch, soil scientist at The Morton Arboretum, discusses his experiments with aerated compost tea. Topics in this lecture include what makes “good dirt” in the urban landscape, Dr. Scharenbroch’s process for making aerated compost tea, as well as his results in comparing aerated compost tea to other treatments.
