Dr. Rudnick’s research focuses on improving irrigation management strategies for commonly grown crops and rotations found in the semi-​arid climate of west central Nebraska. His research team’s projects include:

  • Evaluation of deficit irrigation strategies for maize and soybean under center pivot and subsurface drip irrigation systems.
  • Integration of variable rate irrigation and nitrogen fertilizer management.
  • Assessment of the effects of residue removal across landscape zones on maize yield and crop water use.
  • Field and laboratory evaluation of soil water monitoring equipment.

On his participation with the Ogallala Water Coordinated agriculture project, Dr. Rudnick says: “I hope that the OWCAP project will better define current and upcoming methods to manage water across the Ogallala Aquifer region, provide producers with the necessary information and proper training to effectively implement technology, such as soil water monitoring equipment, into their operations, and advance our understanding on how to spatially and temporally manage water within a field using various sources of information and technology.”
