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. There is no other compost testing program available to compost producers or compost buyers that give you this type of information. STA program certification help you sell more compost through consistent national lab standards, increased attention to the characteristics of your product, marketing tools, and ultimately increased customer confidence.
