3. Fill out a separate form for each sample.

Please Note

You are responsible for the correct information getting to the lab. Be sure to check for:

• Include any and all test request worksheets requested for each sample.
• Include any special instructions for each of your samples.
• Include forms with your sample when you ship it.

Selecting Your Sample

Make certain the sample is representative of the entire seed lot. Improper sampling is the greatest source of error in seed testing. The Colorado Seed Laboratory takes every precaution to insure accuracy of tests, but the value of the test depends on the extent that the sample represents the seed lot. Please refer to the AOSA Rules for Testing Seeds for procedures.

Here are the basics for sample collection:

Package Your Sample for Shipping

1. Samples should be in closed containers that will not open during shipping. Cloth seed bags or double bagged zipper bags work best.
2. When shipping multiple samples together, be sure to clearly label each sample.
3. DO NOT SHIP LOOSE SEED IN SHIPPING BOX OR ENVELOPE
