Illinois Soil Testing Association
Certified Labs
The Illinois Soil Testing Association strives to ensure that member labs always provide
their clients with accurate, reliable and consistent data. This is accomplished through
lab participation in the ISTA – Lab Accreditation Program (LAP), which utilizes soil
analyses data developed through the Agricultural Lab Proficiency (ALP) Program, a
national testing program. Members submit their data to the ISTA – LAP program in three
four-month cycles each year.
Labs must meet certain qualification standards each cycle to remain certified. (The
rules of certification may be found by clicking on the “ISTA-LAP Rules” section on this
site’s header bar.) The following member labs have met the qualifications for
