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:
– Bulk seed:
Hand sample or use a probe so that all areas of the seed lot are represented. If the seed is in a bin, sample it from the top, center, sides, and bottom. It might be more appropriate to collect subsamples as the seed is being transferred from a truck or bin.
– Bagged seed:
For seed lots of one to six bags, sample each bag. For lots of more than six bags, sample five bags plus 10% of the number of bags in the lot. Regardless of lot size, it is not necessary to sample more than 30 bags.
