Cover crop dos and don’ts: lessons learned about cover crops, corn growth, diseases and pests

Iowa State University professors and extension specialists Mark Licht and Alison Robertson.

AMES, Iowa — Iowa Learning Farms, in partnership with the Iowa Nutrient Research Center and Conservation Learning Group, will present a virtual cover crop field day at 1 p.m. CST Dec. 16.

The event will feature live conversation with Alison Robertson, professor and extension field pathologist in agronomy at Iowa State University, and Mark Licht, assistant professor and extension cropping systems specialist in agronomy at Iowa State University.

The field day will explore the potential benefits and impacts of planting corn into a living winter cereal rye cover crop. While the field day will primarily focus on the Iowa trial, the research project has replicated sites located in 15 states across the country. Building on existing research trials, the team is examining different termination dates, both before and after the planting of corn, to determine the impact on diseases, weeds and both pest and beneficial insects.

Participants in Iowa Learning Farms virtual field days are encouraged to ask questions of the presenters. People from all backgrounds and areas of interest are encouraged to join.
