Compost Analysis
Colorado Analytical Laboratory is certified by the U.S. Composting Council for their Seal of Testing Assurance program.  We are one of only a handful of labs in the country that have achieved this certification.  A complete STA package is offered for producers participating in this program.  We also offer packages for routine monitoring when a full STA package test is not required.
