Compost Testing

Compost testing is important for characterizing the beneficial physical and chemical properties of a compost, as well as, for identifying potential problems with compost use.

 

 

 

Basic Compost Tests

These tests include analyses for percent solids, organic matter, soluble salts, and carbon:nitrogen ratio. Compost Tests 1B and 1C include additional tests for nutrients. Test 1A is recommended as an initial test for feedstocks to help determine appropriate mixing ratios. This test may also be used as a basic test for finished compost although nutrient testing (Compost Tests 1B or 1C) on finished composts is recommended.
