2012 Manure Analysis Proficiency (MAP) Laboratories
Laboratories participating in the Manure Analysis Proficiency (MAP) Program receive unknown manure samples to
analyze at least twice a year. This is the only program of its type in North America. Their results are compared with
other laboratories in the program, and this helps all the laboratories improve their manure analysis methods and
brings the industry results closer together. Based on their results, some laboratories are invited to become certified
for manure testing.
The following laboratories, arranged by state or province, participate in the 2012 MAP Program:
