Temporary seeding establishes temporary cover on disturbed areas by planting appropriate rapidly growing annual grasses or small grains. Temporary seeding provides erosion control on areas in between construction operations. Grasses, which are quick growing, are seeded and mulched to provide immediate, temporary soil stabilization. It effectively minimizes the space of a construction site prone to erosion and should be used everywhere the sequence of construction operations allows vegetation to be established.
Temporary seeding should be applied to exposed soil where additional work (grading, etc.) is not scheduled for more than 21 days. Permanent seeding should be applied if the areas will be idle for more than one year.
