Dr. Kelsey Griesheim is Assistant Professor of Soil Fertility at North Dakota State University. She completed her PhD at the University of Illinois, where she worked under Dr. Richard Mulvaney conducting field evaluations to measure fertilizer uptake efficiency of various application types. Monte and Dr. Griesheim take a deep dive into her studies of nitrogen.

She gives us a lot to think about like when we apply nitrogen, we’re fertilizing our crops, but we are also fertilizing the microorganisms. And that, Dr. Griesheim points out, is why nitrogen management is so difficult, because we have to take into account the fact that that nitrogen is not just being used by the plants, it's also being used by microorganisms in the soil. And they’re often, a lot better at scavenging nitrogen than the crop is.

Kelsey Griesheim grew up in Mt. Pulaski, Illinois and completed her BS, MS, and PhD from the University of Illinois in Urbana, Champaign. She was hired as assistant professor of soil fertility at North Dakota State University (NDSU) in February of 2023. While at Illinois, she worked under Dr. Richard Mulvaney conducting field evaluations to measure fertilizer uptake efficiency of various application types using 15N as a tracer. She is currently building a research program at NDSU to tackle the same issues for North Dakota producers.
