The analysis you receive from our laboratory is indicative of the sample submitted. Therefore, to evaluate the true quality of a seed lot, certain considerations must be made in advance to ensure a representative sample is submitted.
Sampling Procedures:
When possible (regardless of the container size), use an appropriate probe to sample seed. Hand sampling is acceptable if the result is representative of the lot. Sub-samples of bulk seed should be taken in equal portions at several evenly distributed locations in the container. For bagged seed, a minimum of 5 bags plus 10% of the bags in the lot (not to exceed 30 bags) should be sampled. Once the sample is obtained it can be mixed and divided down to desired testing weight. For more information on sampling techniques and obtaining or using probes, please contact the lab.
Packaging Samples:
Please remember, when submitting a sample to the lab use either a Seed Service Lab envelope or submit in a leak proof container and accompanied with a completed Seed Test Submittal Form (RS-61-26-1109).
If you have questions regarding seed testing, prices or how to submit a sample, please contact our office.
The preferred packaging when submitting seed samples to the lab is to use a pre-printed seed sample envelope provided by the seed laboratory. This envelope is designed to minimize seed leakage during shipment. Additionally, this envelope has a form on the back that you simply complete before mailing the sample to us. Contact the seed program office to request envelopes.
Alternately, you can submit seed samples to the lab inside another suitable container. However, please be aware that envelopes and bags not designed as seed sample containers can easily leak and tear during transit, making your sample inappropriate for testing. If you choose to use another type of sample container for your seed, make sure it is securely sealed and durable enough to resist damage. Important! If you do not use the pre-printed envelope shown above, be sure to complete a Seed Sample Submittal Form for each sample submitted to the lab. A completed form should accompany each sample submitted.
Shipping Samples:
If you are not able to use a pre-printed sample envelope when submiting sample to the seed lab, be sure to use a durable and tightly sealed container. Plastic sealed zip bags are not recommended. Improperly packaged containers spill during shipment and cannot be tested.
When sending samples via the postal service or common carrier, please take time to make sure the sample is properly packed. Envelopes and small bags of seed should be packed tightly in a box using packing material like newspaper or styrofoam peanuts to prevent shifting during shipping. Bags that shift during shipment can be easily damaged, meaning the samples could get mixed and would not be meaningful to test.
