Biography

Dr. Kovács born and raised in Hungary, where he grew up in a small town, in the country’s primary agricultural production area. Péter received his M.S. degree in agricultural engineering at the Szent István University. He participated in a double degree program through the Erasmus student exchange program to earn his M.S. degree in geographical information management at Cranfield University in the United Kingdom.

Dr. Kovács participated in farm exchange program sponsored by the Hungarian Department of Agriculture and Rural Development. He has worked on a family farm in west central Minnesota, and witnessed the adaptation of the use of precision agriculture tools in crop production.

During his Ph.D. studies at Purdue University he was also involved teaching labs for undergraduate courses, and was a graduate advisor for the Agronomy Club.

He is also actively involved in the reviewing process for several International Journals.

Dr. Kovács has joined South Dakota State University in 2016 with research and teaching appointment. His research focus is on precision agriculture cropping systems.

Areas of Research

  • Precision agriculture
  • Cropping systems
  • Plant nutrition
  • Tillage systems
  • Applied crop physiology

Goal of the research program to improve the production of crops relevant to South Dakota using precision agriculture techniques while keep environmental stewardship in focus. My research focus is to improve crop production and input (e.g. nutrient, seed, etc.) use efficiency through the understanding of genotype x environment x management practice interactions and incorporate precision agriculture and remote sensing techniques into crop management and (immediate or future) decision making process(es).
In addition, we address today’s agronomic challenges and evaluate upcoming production systems and resources.
