Native Seed Rate Chart
Notes:
1. List of native seeds vary from region to region. See your local county extension office for list of native seeds in your region.
2. Seeding rates vary greatly with variations in types of seeds being seeded. The seed rate chart above is based on a seed mix of
5.7# of pure live seed per 11.1# of bulk. The pure live seed mix was Big Blue -1.5#, Little Blue -.8#, Side Oats Grama -.6#,
Western Wheat Grass -1#, Switch Grass -.3#, and Indian Grass - 1.5#.
3. Factors which will affect seeding rates are: weight, size, relative humidity, and moisture content of the seed, ratio of inert material
to seed, different proportions of seed types affecting density, and ground preparation.
4. To help insure an accurate seeding rate, Great Plains recommends that you test and adjust your seeder per the seed rate
calibration procedures provided on page 52.
