CBE Seminar: Making sense of the mess: The role of biofertilizers in sustainable agriculture
- Thursday, November 7, 2019 from 4:10pm to 5:00pm

Hannah Goemann is PhD student in MSU’s Department of Microbiology & Immunology, where she works for Dr. Brent Peyton studying nitrogen-fixing cyanobacterial biofertilizers (CBF). Hannah will discuss her work to determine the effects of CBF on microbial community dynamics using next generation sequencing in the context of a three-year field study of perennial grass production for bioenergy. Due to their high biodiversity, soil microbial communities are “messy” systems of complicated interactions between many organisms including bacteria, fungi, and microfauna that play vital roles in ecosystem function.
Interest in biofertilizers is increasing as they are less environmentally damaging than chemical fertilizers and have been shown to benefit microbial diversity and function. However, fundamental questions remain regarding crop specificity, efficacy during environmental variation, and the use of different biodiversity indices to predict soil nutrient cycling. Deep spatial and temporal sequencing in a field setting, complemented by controlled greenhouse studies, offers the potential to significantly advance our understanding of the short- and long-term effects of CBF on agricultural production, soil biodiversity and ecosystem function.
