Clarity
Similar to a nutrition label, the STA Program’s Compost Technical Data Sheet (CTDS) includes test results, a list of ingredients, and recommended directions for use..
Consistency
The STA Program provides checks and balances within a network of compost producers and labs who test their product, to ensure proficiency and consistency with testing procedures and compliance. This provides apples to apples comparisons of compost properties.
Confidence
Similar to trusting a vehicle history report when purchasing a vehicle, the STA’s CTDS report provides consumers with confidence and knowledge of what is in the compost and how it was produced.
The program – created in 2000 – is the culmination of research and discussion by many of the leading compost research scientists in the United States. Currently this is the only compost testing program available providing this. Joe Lamp’l from PBS’s Growing a Greener World explains why he values the program in this video.
