STA analysis - STA logo

This STA analysis is an example of the laboratory report received each month for McGill SoilBuilder premium compost manufactured by McGill facilities in the U.S.

While feedstocks received and processed at all facilities are similar each month, they are not identical.  This may result in slight variations in lab results.  For a copy of the most recent report from the facility of origin for your next compost order, please contact compost sales.
