Many of our educational field days and workshops focus on manure regulatory issues. This program will include a regulatory update, but will help participants go beyond regulatory issues to look at emerging issues in manure management. This clinic will include a combination of classroom and field activities. Topics will include: pathogens and antibiotics concerns in manure, siting facilities, composting on-farm mortalities, no-till manure application issues, and trends in feed management.
