Pure Live Seed

Seed is provided in Pure Live Seed (PLS) unless otherwise stated.

Pure Live Seed (PLS) expresses the viable seed content of a seed lot using its purity and germination or viability test results. It helps you compare seed lots and calculate how much bulk seed is needed to meet a specified PLS planting rate.

PLS weight and bag weight

PLS weight is not the same as the total weight of seed in a bag. For example, a lot with 80% purity and 75% viability contains 60% PLS: 80 × 75 ÷ 100 = 60. Supplying 10 lb PLS from that lot requires about 16.67 lb of bulk seed.

Use the current seed test and the stated basis of the mix specification. Germination calculations may include applicable hard or dormant seed. Seed-count estimates also require the number of seeds per pound; PLS alone does not provide a seed count.

What to check when buying a mix

Check whether each rate is stated in PLS pounds, bulk pounds, or a combination. A mix with both bases should not be described as having an all-PLS total.

PLS does not remove weed seeds or guarantee establishment. Review the seed label and analysis for weed content, and match site preparation, planting conditions and follow-up management to your project.

Rates retain the stated bulk or Pure Live Seed (PLS) basis for each ingredient. If both appear, the total is not an all-PLS or all-bulk rate. Seed counts are catalog estimates; rounded rows may not sum exactly to the displayed total.

The class name and a catalog recipe do not by themselves certify project acceptance. Confirm the specification edition and any approved changes before ordering.
