Cover Crops in Midwestern Cropping Systems
Instructor: Mark Sulc, sulc.2@osu.edu

Meeting Day/Time: Mondays 2:00 PM - 4:00 PM
Location: Kottman 334 (Columbus) and Williams 123 (Wooster)
In this current topics course, the students will explore and discuss the peer-reviewed literature to identify what is known concerning the use of cover crops in agronomic cropping systems. The focus will be on grain crop systems in the Corn Belt region but examples from other regions will be considered that inform the potential of cover crop use in this region. We will answer such as questions as, what are the benefits of cover crops and what are the opportunities and challenges for using cover crops within our grain cropping systems? Possible topics to explore include: effects of diversifying cropping systems with cover crops (eg. environmental and subsequent crop effects), managing cover crops for weed, insect, and disease control within cropping systems, cover crop species selection, rotational strategies for cover crop incorporation into cropping systems, establishment and termination of cover crops, economic considerations of cover crop use, soil benefits of cover crops, and options for generating additional income from cover crops. The students will identify the gaps in our knowledge of cover crop use within Midwestern grain cropping systems. The exact outline of covered topics and scheduling of the course will be determined in a collaborative manner between the instructor and the students.
