    Scholarships available! The Organics Recycling Association of Ohio is offering professional development grants for the Ohio Compost Operator Education Course. Deadline is March 1, 2017.    Grant application
  • ODA Certified Livestock Manager (CLM) Training. March 1-2, 2017, Reynoldsburg, Ohio. Learn about best management practices for handling and using manure. Designed for farmers or custom applicators who need to be licensed, but open to anyone interested.   Details and registration

Online training and resources:
  • ONLINE: Ohio Mortality Composting Certification Workshop. Composting dead animals is an environmentally friendly and cost effective disposal method, but Ohio livestock producers must attend a course for certification or complete the online training. Here’s how to sign up for the online course:

  • NEW!  Manure and Compost: Nitrogen Availability in Organic Production. OSU Extension factsheet discusses factors that influence the nitrogen content and is applicable to non-organic crop production too.

  • AVIAN INFLUENZA TOOLS. Composting on the farm is considered one of the best options for disposal of a large number of birds in the event of an AIN1 outbreak. These tools will help in planning:

The purpose of OCAMM is to research, develop and communicate sustainable strategies for the management of animal manure and nutrient inputs on Ohio farms. To achieve this purpose, strategies such as composting, land application, facility design, and feed management will be studied for their ability to recycle nutrients, reduce the need for chemical fertilizer and pesticide inputs, improve soil fertility, reduce odor emissions, and improve environmental stewardship. OCAMM program participants include livestock producers, livestock system consultants, equipment manufacturers, trade associations, compost users, and public agencies as well as faculty and staff at OSU.
