Establishment of Seeded Grasslands for Wildlife Habitat in the Prairie Pothole Region


Tables


Table 9. Seeding rates based on pure lioe seed (PLS) and bulk pounds per acre for introduced cool-season grasses and legume stands in all Major Land Resource Areas in the area of guidelines applicability.

Seed quality**
Species Optimum lb/acre PLS* Percent of full seeding Amount of PLS (lb/acre) Purity Germination Factor*** Bulk seed (lb/acre)
Tall wheatgrass 11.0 0.40 4.5**** 95 85 1.25 5.6*****
Intermediate wheatgrass 10.0 0.38 4.0 95 85 1.25 5.0
Alfalfa 4.4 0.22 1.0 95 90 1.2 1.2
Sweetclover 3.4 0.15 0.5 95 90 1.2 0.6
Totals 10.0 12.4


   
* Based on recommended full seeding rate of 20 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.

*** Conversion 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.
