Practice Standards and Specifications 6.10

Definition: Planting rapid-growing annual grasses, small grains, or legumes to
provide initial, temporary cover for erosion control on disturbed areas.
Purpose: To temporarily stabilize denuded areas that will not be brought to final
grade for a period of more than 21 calendar days.
Temporary seeding controls runoff and erosion until permanent
vegetation or other erosion control measures can be established.
Planning Considerations: Temporary seeding provides protection for no more than 1 year, during
which time permanent stabilization should be initiated.

Specifications: Complete grading before preparing seedbeds, and install all necessary erosion
control practices. If soils become compacted during grading, loosen them to a
depth of 6-8 inches.
SEEDBED PREPARATION
Good seedbed preparation is essential to successful plant establishment. A good
seedbed is well pulverized, loose, and uniform.
Liming—Apply lime according to soil test recommendations. Apply limestone
uniformly and incorporate into the top 4-6 inches of soil. Soils with a pH of 6 or
higher need not be limed.
Fertilizer—Base application rates on soil tests. Incorporate into the top 4-6
inches of soil. If a hydraulic seeder is used, do not mix seed and fertilizer more
than 30 minutes before application.
Surface Roughening—Groove or furrow slopes steeper than 3:1 on the contour
before seeding.
PLANT SELECTION
Select an appropriate species or species mixture for seeding in late winter and
early spring.
SEEDING
Evenly apply seed using a cyclone seeder (broadcast), drill, cultipacker seeder,
or hydroseeder. Hand broadcasting is not recommended because of the
difficulty in achieving a uniform distribution. Small grains should be planted no
more than 1 inch deep, and grasses and legumes no more than 1/2 inch.
MULCHING
The use of an appropriate mulch will help ensure establishment under normal
conditions, and is essential to seeding success under harsh site conditions. If the
area being mulched is subject to concentrated waterflow, as in channels,
anchor mulch with netting.

Maintenance: Reseed and mulch areas where seedling emergence is poor, or where
erosion occurs, as soon as possible. Do not mow. Protect from traffic as
much as possible.
