Seed samples sent for testing must be representative of the seed lot. See below for procedures and follow the instructions precisely for the best testing results. Please submit samples for testing as soon as possible after they are collected.

Sampling Bulk Seed

  • equal portions should be collected from evenly distributed areas. 
  • bins need to be probed from the entire depth with probes being taken in different parts of the bin
  • it is convenient to sample the seed as it goes into or out of a bin or during conditioning

Sampling from Bags

  • follow different paths for each probe or take handfuls from well-separated points.
  • in lots of 6 bags or less, sample all bags.
  • in lots of more than 6 bags, sample a minimum of 5 bags plus 10% of the number of bags in the lot.
  • Do not sample more than 30 bags
