STA Certified Compost
Buying high quality compost begins with knowing what you have. The STA Certified Compost Program is founded on highly researched compost testing methods, and careful lab oversight to give you confidence the test results are accurate
for the product you purchase through the STA Certified Compost Program.
The science behind the development of the STA Certified Compost Program is contained in the highly researched “Test Methods for the Examination of Composting & Compost” (TMECC). This publication gives a breakdown of the physical, chemical
and biological tests used as part of the program.
STA labs are held to high standards for implementing the compost test methods through the STA’s Compost Analysis Program (CAP). CAP tests the STA labs’ quality against the other labs in the program.
