Studying Soil Health on Green Roofs
Green roofs are being increasingly utilized on urban buildings for their ability to retain storm water, insulate buildings, and cool urban heat islands. Strong soil health is required for such services, yet few studies have examined the soil biodiversity and functioning in green roofs. Mycorrhizal fungi are an important indicator of soil health, forming symbioses with plant roots, enabling nutrient and water absorption a contributing to below ground carbon sequestration. Faculty and students are studying the abundance of mycorrhizal fungi on Loyola University Chicago’s green roofs as indicators of soil health.
