Compost Testing

Store / Compost Testing
Not all compost tests are the same- TPS Lab offers two different tests for the essential qualities of compost:

Active Organic Matter - This measures the amount of organic matter that has been decomposed or digested by microbes into useable material by plants.

Loss On Ignition (LOI) - This measures the total organic matter content that is useful in determining how much raw organic matter is available for microbial food to digest into plant-available nutrients.

TPS Lab is the 11th approved US Composting Council Seal of Testing Assurance ( USCC STA ) laboratory for all participating STA composters in the United States and Canada! You can find us listed at http://compostingcouncil.org/labs/.
