Ranae Dietzel

Since 1983.


I began as a biologist, took an interest in soils, and now think about how soils and plants interact at a molecular to field scale both during and after the life of the plant. Modeling helps me think -- I use APSIM and R.


My roots are in Iowa and I am passionate about reconciling differences in agricultural production, environmental quality, and rural quality of life in our state. My husband (mostly) and I are seeing if we can make a grass-based dairy operation work in Central Iowa.


I have a great husband and two amazing kids. Both sets of my grandparents and almost all of their kids/grandkids/great-grandkids live within 50 miles of me, which is nice. I used to have a lot of fun hobbies and I'm sure I will again someday.

What I Do

I am a post-doctoral research associate in Iowa State University's Department of Agronomy's Integrated Cropping Systems Lab.


We do not know enough about what goes on in temperate-region soil during the winter. As a NIFA-ELI Fellow, I am going to tackle this problem all the way to modeling spring-thaw nitrous oxide fluxes.

Soil C Dynamics

My PhD focused on differences in soil C dynamics between corn and prairie cropping systems. I am continuing this work by focusing on the effect of depth on C loss and/or stabilization in these two contrasting systems. I plan to use the soilR package for soil C model intercomparison.

Integrated Cropping Systems Lab

I am extremely fortunate to work in this great lab group! This link will take you to everything we do and some wonderful online tools. I highly recommend clicking here.

Data Stewardship Co-instructor

Data and R are a big part of my life. I want to help scientists like myself be better at what we do. In Fall 2016, I teamed up with a data skills master to teach soil-plant-atmosphere grad students how to deal with data.

Things I did (CV)

My BA at University of Minnesota-Morris, my Master's at Cornell, my PhD at Iowa State, and some really great jobs along the way. Plus publications!

Things I don't do

Clean my house. Exercise. Read fiction. Shop. USPS. Return borrowed items. Carry a wallet.
