Other Information

Larry Purcell grew up in the foothills of the Appalachian mountains in Gainesville, Georgia. He is married to Rebecca Zorn Purcell and they have two sons, Jacob and Carlin, and a daughter, Corrie.

Research Emphasis

Larry C. Purcell is a Crop Physiologist, and his research focuses on genetic differences in the efficiency with which crops use essential resources, particularly water and nitrogen, and how these resources can be managed effectively for crop production. Dr. Purcell is recognized as an authority in soybean on the response of nitrogen fixation to drought and for collaborative research developing agronomic drought tolerance.

Dr. Purcell has published 106 peer-reviewed manuscripts, 20 book chapters (including two chapters for ASA/CSSA monographs), and over 150 abstracts. He also has been awarded three patents.

Dr. Purcell served on the Crop Science Editorial Board for 6 years as an associate editor and for 3 years as a technical editor. He served 3 years on the Crop Science Society of America Board of Directors representing the Crop Physiology and Metabolism Division, and he is currently an associate editor for the Journal of Plant Production. Dr. Purcell teaches both graduate and undergraduate classes and works closely with graduate students.

Courses Taught

  • CSES 5033 - Plant Nutrition and Soil Fertility, (Spring, even years, co-taught with Dr. Richard Norman)
    A discussion oriented course for graduate students and undergraduate students (with permission) on the importance of plant nutrition in crop physiology and metabolism and the importance of chemical, biological and physical processes in soil that influence nutrient availability.  Topics for discussion concerning plant nutrition include: nutrient uptake mechanisms and kinetics, active and passive uptake, water uptake, nutrient transport in xylem and phloem, carbon and nitrogen metabolism and regulation, source/sink relationships and macro- and micro-nutrient roles in enzymatic/metabolic processes.  Topics of discussion concerning soil fertility will concentrate on how elemental forms, chemical mechanisms and biological and physical factors in the soil affect nutrient availability and nutrient management as well as research techniques used in soil fertility.
  • CSES 462V - Crop, Soil, and Environmental Sciences Internship (Fall and Summer, co-taught with Dr. Kris Brye and Dr. Jason Norsworthy)
    CSES Internship provides a professional work experience in the general areas of crop management and science, water and environmental sciences, and pest management. Students work closely with their sponsors to develop an appropriate project for approval. Credit varies from 1 to not more than 3 hours.


  • Ph.D from University of Florida in Agronomy in 1992
  • M.S. in Agronomy (Crop Physiology) from the University of Georgia in 1984.
  • B.S. in Agronomy from the University of Georgia in 1981
