Table 8. Seeding rates based on pure live seeds (PLS) and bulk pounds per acre for mixed-grass prairie grasses on silty range site-Major Land Resource Area 55B.

Seed quality**
Species Optimum lb/acre PLS* Percent full seeding Amount of PLS (lb/acre) Purity Germination Factor*** Bulk seed (lb/acre)
Western wheatgrass 11.9 0.15 1.79**** 85 80 1.45 2.6*****
Thickspike wheatgrass 8.5 0.05 0.43 95 85 1.25 0.5

Switchgrass 4.5 0.025 0.11 95 80 1.3 0.1
Totals 8.69 16.4


* Seeding rate ia adjusted for species differences in seedling vigor and
rate of establishment. Refer to Table 4 for actual rate, PLS per square
foot.

** Percent purity and germination are shown as minimum standards for good
quality seed. Use actual purity and germination of seed lot to calculate
bulk pounds.

*** Converaion factor, Table 3 (Conversion factors to determine pounds of
bulk seed needed for 1 pound of pure live seed).

**** Optimum lb/acre PLS x Percent of full seeding = Amount of PLS.

***** Amount of PLS x Seed quality factor = Bulk seed.
