All seed has its own line number, printed on the side of the seed sack, and each line of seed has its own seed analysis certificate. The seed analysis certificate describes the quality of a line of seed, laboratory tested in a standard way.

The National Seed Laboratory, run by AsureQuality, produces a certificate for ALL certified seed. Certificates are available on all certified Barenbrug seed lines.

• Some ryegrass, red clover and brassica cultivars are tetraploids.
• Tetraploids have larger seeds than diploids, so they must be sown at higher rates.
• In perennial and hybrid ryegrass, tetraploids need different management for best performance

Sowing rates for individual situations vary.
