Manure Sampling Procedure

Instructions and information.

Sampling and Mailing Procedure

The sample should be representative of the entire material sampled. This may require multiple samples if the consistency of the manure varies significantly within the storage. Often the best and most convenient time to collect a manure sample is when the manure is being removed from the storage and spread.

  • Collect small amounts of manure in a clean bucket from many places within the manure or sample periodically as the storage is emptied. This large composite sample should then be thoroughly mixed and a small subsample sent to the lab for analysis.
  • Liquid storages must be agitated before sampling.
  • Solid manure samples should include both manure and bedding.
  • Fill the sample bottle, leaving ½ inch of air space, label the bottle and fill out the sample information form completely and accurately.
  • Include a check or money order for the appropriate amount payable to The Pennsylvania State University. Or print the credit card authorization form and attached it to the submission form.
  • Be sure the sample bottle is securely closed and pack it, the sample information sheet, and your check in the mailer.
  • Attach proper postage and mail directly to the lab as rapidly as possible.

Important Note on Penn State's Manure Management Program

This program is being conducted as part of Penn State’s educational and extension program for developing improved manure management systems in Pennsylvania. A copy of your results will be sent to your county agent who will be better able to answer questions and assist you with your manure management program. The results of the analyses will also be entered into a state-wide database for summarization. No individual results will be released outside of Penn State without prior permission.

Your comments on any part of this program would be welcome. Please send them to the Pennsylvania State University, 111 Ag Analytical Srvcs Lab, University Park, PA 16802, tel: 814-863-0841.
