  • Manure Processing Technology (MPT) Assessment.  A decision strategy to help livestock farmers evaluate the feasibility of manure handling and processing products and systems.  Click on the title below to access:
    MPT Manual
      Provides information on using the MPT Excel Workbook, examples, questions for further evaluation, and information sheets on seven technologies. 
    MPT Excel Workbook
      Input livestock and crop production and the decision tool calculates nutrient balance and determines the feasibilty of six manure processing technologies.

  • 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:
    1)      Go to http://campus.extension.org/ and login if you have an account or create one
    2)      Click on “Agriculture & Animals” and scroll down to the course ‘Mortality Compost’  NOTE: The cost is $17 and can be paid with a credit card or PayPal account.The course consists of 8 presentations and takes about 3 hours, plus a 25 question exam.  It can be completed in 1 sitting or spread out over several days.

Recently held programs:
  • Ohio Mortality Composting Certification Workshop. January 22, 2014 at Planktown Market, Shiloh, Ohio.  Composting dead animals is an environmentally friendly and cost effective disposal method, but Ohio livestock producers must attend a certification course.  

  • Manure Science Review 2013.  Tuesday, August 6 at Hord Livestock, Bucyrus, Ohio. Learn how manure nutrients change as you pump and what to do about it.  See demonstrations, including the Subsurfer, a solid manure injector, and the Nutrient Boom, for application on standing corn!

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.
