Jha, Prashant

My research program is focused on improved understanding of weed biology and ecology to develop effective, integrated weed management strategies in corn and soybean production systems of Iowa and Midwest, optimization and stewardship of herbicide application technology and herbicide use, and understanding the evolution of herbicide resistance including genetic/molecular and physiological mechanisms, and other factors influencing weed population dynamics and management in agroecosystems. This includes emphasis on late-season weed seed bank management and reducing weed seed inputs at harvest. My research interest also includes UAV and ground-based hyperspectral imaging and machine learning of weed species in-crop for developing weed maps and for early detection of herbicide-resistant weed biotypes in the field. My statewide extension and outreach program is focused on current and emerging weed problems in Iowa and providing research-based information to growers on cost-effective, multi-tactic approaches for prevention and mitigation of herbicide-resistant weeds in agronomic crop production systems. I serve as the herbicide evaluation and demonstration program leader, with the ultimate aim to develop cost-effective and sustainable weed control recommendations for corn and soybean producers in Iowa. My programming supports extension, agribusiness, governmental agency programs, and other educational needs throughout Iowa.

My research interests include sustainable agriculture, the production and management of alternative cropping systems, and agronomic education. The majority of my responsibility is in 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. I teach AGRON181 Introduction to Crop Science, AGRON392 Systems Analysis in Crop and Soil Management, AGRON496 Agricultural Systems of New Zealand, AGRON497 Agroecosystems Field Course, and SusAg515 Integrated Crop and Livestock Production Systems. I also advise undergraduate and graduate students. I am currently serving as the Associate Chair for Academics and the Director for the M.S. in Agronomy Program.

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.

Licht, Mark

Mark Licht is an Assistant 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 an associate professor of integrated cropping systems at the Department of Agronomy. His research aims to predict impacts (e.g. climate change), explain causes (e.g. for high/low yields or nitrogen loss) and design future strategies to improve crop productivity and environmental sustainability across spatial and temporal scales. His approach combines field experimentation on soil-plant-atmospheric processes to fill knowledge gaps and use of agricultural systems process-based models to explain Genotype x Environment x Management interactions and enable prediction and design at scale.

Moore, Kenneth

Dr. Ken Moore is Charles F. Curtiss Distinguished Professor in Agriculture and Life Sciences and Pioneer Hi-Bred Agronomy Professor in Agronomy at Iowa State University where he has been a member of the faculty since 1993. He holds a B.S. (1979) degree from Arizona State University and M.S. (1981) and Ph.D. (1983) degrees in Agronomy from Purdue University. He held faculty positions at the University of Illinois (1983-87) and New Mexico State University (1987-89), and was a USDA/ARS Research Agronomist and adjunct faculty member at the University of Nebraska, Lincoln (1989-93). His research focuses on the development and improvement of biomass crops and cropping systems. He is Project Director for the USDA-NIFA-CAP project CenUSA: Sustainable Production and Distribution of Bioenergy for the Central USA (2011-19). He is the founding director and led the development of the Master of Science in Agronomy distance education program (1995-2017). He served two terms (2010-2017) on the ISU Graduate Council and was its Chair during the 2015-16 academic year. He teaches a graduate course on quantitative methods and the design and analysis of agronomic experiments (Agron 526). He has worked on collaborative research and education projects in Morocco, Costa Rica, and New Zealand where he was a Senior Research Fellow with AgResearch Grasslands in 1998. Dr. Moore served as President of the Crop Science Society of America (CSSA, 2004) and President of the American Society of Agronomy (ASA, 2008). He served on the editorial boards of Agronomy Journal and Crop Science, and was the founding editor of the e-journal Crop Management. He is co-editor of Forages Volume I: An Introduction to Grassland Agriculture (6th & 7th eds.) and Forages Volume II: The Science of Grassland Agriculture (6th and 7th eds.). Dr. Moore is a member of Gamma Sigma Delta, Phi Kappa Phi, and Sigma Xi and has been recognized with Outstanding Young Scientist and Merit Awards by the American Forage and Grassland Council, the Young Crop Scientist Award by CSSA, and the Agronomic Service Award and Distinguished Service Award by ASA. He is a Fellow of ASA, CSSA, and the American Association for the Advancement of Science (AAAS).
