• Do nutrients limit soil carbon sequestration?

In our fourth webinar of 2022, “Do nutrients limit soil carbon sequestration?,” our speakers, Dr. Adrienne Keller (University of Minnesota) and Dr. Stuart Grandy (University of New Hampshire) will address how nitrogen influences soil carbon dynamics potentially limiting the potential for carbon sequestration.

Time: May 17th 2022, 3:00 PM Eastern.

Adrienne Keller is a post-doctoral research scientist in Dr. Sarah Hobbie’s lab at the University of Minnesota. She is working with the Nutrient Network, a coordinated research network that includes more than 130 grassland sites worldwide, to examine the effects of nutrient pollution and altered grazing regimes on grassland plant and soil properties. Adrienne is also a researcher with the new Minneapolis-St Paul Metropolitan Area (MSP) urban Long-Term Ecological Research site, where she is working on a collaborative, interdisciplinary project examining how social and ecological factors influence canopy diversity and resilience across the MSP metro area. She completed her PhD in Ecology at Indiana University where she studied the effects of tree communities on soil carbon and nutrient cycling in temperate forests. Adrienne also holds a M.S. in Resource Conservation from the University of Montana and a dual B.A. in Biology and Geography from Macalester College.

Stuart Grandy is a Professor of Soil Fertility and Biogeochemistry and co-director of the UNH Center of Soil Biogeochemistry and Microbial Ecology (Soil BioME). His lab examines how agroecosystem management influences soil health as well as the microbial processes driving soil organic matter formation and nutrient cycling. The lab is currently focused on the processes regulating from where and how plants and microbes acquire bioavailable nitrogen.
