About USCC STA Program

The US Composting Council’s Seal of Testing Assurance Program (‘STA’) is a compost testing, labeling and information disclosure program designed to give you the information you need to get the maximum benefit from the use of compost.

The program was created in 2000 and is the consensus of many of the leading compost research scientists in the United States. There was no other compost testing program available to compost producers or compost buyers that gives you this type of information. View the Biotown Ag certificate of STA testing below:
