Biography

Gregg is an Associate Professor in the Department of Agronomy and Plant Genetics at the University of Minnesota. He specializes in annual and perennial cropping systems with a focus on maximizing productivity, efficiency, and ecosystem services. Gregg’s work emphasizes applied production strategies that are designed around multi-value outcomes.

Research

A primary goal of the SROC agronomy research and outreach program is to improve the efficiency, profitability, and resiliency of annual and perennial cropping systems. Our program explores applied production strategies that provide multi-value outcomes to improve the economic and environment value of agriculture.   

Our current projects investigate: 

  1. Cropping system resiliency and stability over time and locations
  2. Understanding trade-offs between control of late-emerging weed species and use of cover crops in MN
  3. Winter annual oilseed cover crop establishment and yield
  4. Cover crops to enhance soil properties and water quality
  5. Corn and soybean herbicide evaluations
  6. Minnesota Corn Performance Testing
