• I planted seed and it didn’t come up. What happened? Seed

  Many people with seed germination issues wonder if there was a problem with the seed. However, that usually isn’t the cause. State seed laws require us to monitor seed lot germination by sending samples to certified seed labs to test and verify germination standards.

  There are many factors that can cause seeds to not grow, including:
  Seeds were planted when it was too hot or too cold
  Seeds were planted too deeply/not deep enough
  Seeds received too much water/not enough water
  Seeds were planted in compacted soil

• What is the difference between Pure Live Seed (PLS) and Bulk Seed? Seed

  Pure Live Seed (often referred to as PLS) refers to the percentage of live, viable seed in a bulk amount of seed. This percentage of seed is what is capable of developing into seedlings. PLS provides a standard of comparing the quality of lots of the same species that have different germination and purity. PLS is calculated by multiplying the percent of total germination and the percent of pure seed of a lot.

  Example: 98% purity and 90% germination
  98 x 90/100=88.2%
  Only 88.2 percent of that lot of seed is capable of growing. If you have a 50-pound bulk bag of seed that would give you 44.1 pounds of live seed.

• What is the difference in seeding rate for coated vs. uncoated seeds? Seed

  Most seeding rates are based on a set number of seeds over a certain area. When a coated seed is used, the seed size has been increased, so the rate should also be adjusted to accommodate the larger seed.

• What is the difference in seeding rate for drilling vs. broadcasting? Seed

  Due to the variability of broadcasting seed over the ability to calibrate a drill, seeding rates are often recommended to increase when using the broadcast method.

• How long can I store seed? Seed

  Seed should be stored in a cool (not freezing), dry place with low humidity. When properly stored some seeds can stay viable for years.

• What is seed coating, and what are its benefits? Seed

  Seed coating is a covering applied to seeds that may contain fertilizer, growth promoters or a seed treatment. Seed coating can also be used to increase the size and weight of the seed to aid in planting accuracy.
