Roth, Richard

Dr. Richard Roth is an Assistant Professor and Extension Soil fertility Specialist at Iowa State University.  He joined the Department of Agronomy and at Iowa State in September 2023. His primary responsibilities are nitrogen and sulfur management. Dr. Roth’s research and extension work focuses on engineering and optimizing nitrogen and sulfur management strategies to improve the efficiency and environmental sustainability of cropping systems in the Midwest. He is dedicated to enhancing the agronomic, economic, and environmental performance of these systems.

Wiedenhoeft, Mary

Currently, I am serving as the Associate Chair for Academics and the Director for the M.S. in Agronomy Program. Additionally, I am teaching several classes: AGRON1810 Introduction to Crop Science, AGRON3100 Professional Internship in Agronomy, and AGRON4960 Agricultural Systems of New Zealand.  I also advise undergraduate and graduate students.

My research interests include sustainable agriculture, the production and management of alternative cropping systems, and agronomic education. I am interested in cooperative learning where the classroom becomes a place to learn in a personal, non-competitive environment, to develop understandings and/or skills, and to celebrate learning.

Miguez, Fernando

Fernando Miguez was born in Buenos Aires, Argentina and before coming to Iowa State was a a post-doc at the Energy Bioscience Institute (University of Illinois) working on developing general mathematical models for biomass crops. He has received a M.S. and Ph.D. in Crop Sciences and a M.S. in Applied Statistics, all from the University of Illinois. The research is integrative, involving crop physiology, agronomy, soils, mathematical modeling, statistics and applied spatial analysis with the goal of producing reliable predictions of cropping systems’ productivity, stability and ecosystem services.

The ultimate objective of our lab is to enhance productivity, stability and sustainability of cropping systems for food, feed and fuel in an environmental, social and economic context.

Our approach is to:

  • create and analyze databases of crop performance,
  • integrate field experimentation with statistical and process-based crop models and
  • to produce spatial forecasts of productivity, stability and ecosystem services of cropping systems.

In our research we use a variety of methods:

  • meta-analysis,
  • linear, non-linear and generalized mixed models,
  • process-based crop models,
  • meteorological, soil and land-use databases,
  • parameter estimation,
  • spatial analysis.

Goggi, A. Susana

research interests: Seed physiologist Susana Goggi research interests are developing advanced strategies for minimizing the adverse effects of the production and storage environment on the quality of soybean and corn seeds and developing organic seed protectants as alternatives to chemical seed treatments.

Licht, Mark

Mark Licht is an Associate Professor and Extension Cropping Systems Specialist in the Department of Agronomy at Iowa State University. His extension, research and teaching program is focused on how to holistically manage Iowa cropping systems to achieve productivity, profitability and environmental goals. Research is centered around varied aspects of soybean, corn and cover crop management.

Archontoulis, Sotirios

Sotirios Archontoulis is a professor of integrated cropping systems at the Department of Agronomy. His research aims to predict impacts, explain causes (e.g. high/low yields) and design future strategies to improve crop productivity and environmental sustainability across spatial and temporal scales. His approach combines field experimentation and use of agricultural systems process-based models to explain Genotype x Environment x Management interactions and enable prediction and design at scale.
