Building Soil with Microbes: Compost as Biological Infrastructure
Keisha Ernst from the Catalyst Bio-Amendments and Compost Academy
In Person Location: ISB 221
In this talk, Keisha will explore how biologically focused compost production differs from conventional composting systems designed primarily for waste diversion. She will discuss how microbial communities influence soil structure, nutrient cycling, plant resilience, and water dynamics—and how managing compost as a living biological input can shift the way we approach soil fertility. The presentation will also highlight findings from a two-year field trial evaluating microbial applications in landscape and turf systems, including results showing measurable reductions in irrigation needs alongside improvements in soil performance. Designed for growers, land managers, researchers, and soil enthusiasts alike, this talk offers a practical look at how working with soil microbiology can reshape the future of agriculture and land stewardship. Keisha will also give a live demonstration showing different known types of microbiology!
