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 give you this type of information.
The science behind the development of the STA Program and the various tests that are used is contained in ‘Test Methods for the Examination of Composting & Compost’ (‘TMECC’). This publication includes a suite of physical, chemical and biological tests. These were selected to help both compost producer and purchaser to determine if the compost they are considering is suitable for the use that they are planning, and to help them compare various compost products using a testing program that can be performed by a group of independent, certified labs across the country and in Canada.
