Compost analyses contain a wealth of information, but understanding and using that information can be a challenge, especially with all the other demands on a composter. Few people have done more compost analyses than Assaf Sadeh as manager at Soil Control Lab. Using the Seal of Testing Assurance Compost Technical Data Sheet as a guide, Assaf will review the major sections of the report that help answer the three important questions:

• Is this compost safe (pathogens and metals)?


• Is this compost done (stability and maturity)?


• What is this compost good for (nutrients, contaminants, and other analytes)?
