About Us

SoDak Labs is your trusted seed testing partner located in Brookings, SD. With over 200 years of testing experience in the seed industry, SoDak Labs is an employee-owned business. We provide purity, germination, vigor, trait, ELISA, electrophoresis, and cultivar purity tests. Currently, our facility performs over 100,000 tests on 50 different species annually. SoDak Labs tests according to AOSA or ISTA rules. In addition, we provide training for ISTA sampling and issue both Orange & Blue Certificates.

Our philosophy is to provide quick, agronomically accurate service while continually improving our procedures and processes. Our laboratory processes are set up to have samples identified electronically. Electronic identification allows us to track methods specified by species, monitor equipment and testing conditions, and track/document the entire testing process. Evaluation for germination is conducted with a team approach, which allows for multiple checks within the system to verify results and ensure accuracy. Information is entered on an electronic tablet which decreases transcription errors and allows for reports to be available to customers quickly.

SoDak Labs has a highly trained staff that includes Agronomists, Seed Physiologists, Registered Genetic Technologists, and Registered Seed Technologists. Our staff evaluates all seed testing procedures and are available on-site to diagnose, explain causes, and answer any seed quality questions. Our laboratory has attained ISTA and ISO17025: 2005 laboratory accreditation. Both of these require validation and verification of processes, monitoring and measurement of procedures, training, and continual improvement of our processes for our customers. We believe in improving our customer's experience and want to be a partner in your business.

We believe it is important for seed producers and distributors to understand what seed testing means, which is why SoDak Labs is dedicated to training. Our Seed Academy offers seed biology online courses and seed quality on-site workshops throughout the year geared toward this initiative.
