Forage Focus: Fungal Growth in Stored Forages

In this edition of Forage focus host Christine Gelley, an Extension Educator with The Ohio State University Agriculture & Natural Resources in Noble County, visits Harrison County for an interview with Erika Lyon, OSU Extension Educator for Agriculture and Natural Resources in Jefferson & Harrison Counties. Erika and Christine address concerns about fungal growth in stored forages.
