CERTIFIED LABS

The following member labs have met the qualifications for certification by ALTA as of Oct 2023.  

The Agricultural Laboratory Testing Association (ALTA) strives to ensure that member labs always provide their clients with accurate, reliable and consistent data.  This is accomplished through lab participation in the ALTA-Lab Accreditation Program (LAP), which utilizes soil analyses data developed through the Agricultural Laboratory Proficiency (ALP) Program, an international testing program.  Members submit data to the ALTA-LAP program and it is evaluated every four months.

Labs must meet certain qualification standards each cycle to remain certified.  The rules of certification may be found by clicking on the “Soil Analysis” section on this site’s header bar.
