FLATTENED FIELDS: The decision about what to do with the wind-damaged crop will largely depend if the plants are bent over or snapped off.

Learn to manage downed corn

Sept. 2 webinar offers tips for managing unharvested corn and planning for 2021.

As farmers begin to evaluate the best management options for corn acres with severe derecho damage, Iowa State University Extension is providing a webinar on Sept. 2 that will address challenges and considerations for those acres that will remain unharvested.

The derecho that traveled through Iowa on Aug. 10 affected over 3.5 million acres of corn, creating management challenges not typical to Iowa crop fields, especially on such a large scale.

“Areas of the state worst affected by the derecho will have significant acreage where corn is not harvested,” says Mark Licht, assistant professor in agronomy and Extension cropping systems specialist at Iowa State.

Residue management challenge

“Unharvested corn plants create a significant crop residue management challenge in cornfields across the state,” says Matt Darr, professor in agricultural and biosystems engineering at Iowa State. “This webinar will address key considerations for managing these acres both this fall and next spring with the 2021 crop in mind.”

Attendees will be able to better understand the management options for unharvested fields, including best management practices for using different tillage implements to manage residue, and considerations for these acres going into 2021. Presenters will share information specifically on managing crop residue, cover crops and soil fertility and crop rotation.

Along with Darr and Licht, Prashant Jha, an ISU Extension weed scientist, will present on crop rotation and volunteer corn management.

Must register to view webinar

The webinar will run from 1 to 2 p.m. and is intended for row crop farmers in the derecho-affected area, ag service providers, and ag retailers and farm managers. Certified crop adviser credits will be available, pending approval. The program will be recorded and available on the Iowa State Crops Team YouTube channel afterward.
