F. Application Methods

All seeding equipment shall be free of invasive weeds, seeds, or plant propagules.

The Contractor shall not seed when wind, temperature, and/or other weather and/or ground conditions would hinder proper placement or growth.

The mulch shall be added to the slurry in the hydro-seeder after the proportionate amounts of seed, fertilizer, and lime have been added. The slurry shall then be mixed and applied in such a manner that the rate of application will result in an even distribution of all materials.

Hydroseeding equipment shall be capable of maintaining a continuous agitation so that a homogeneous mixture can be applied through a spray nozzle. The pump shall be capable of producing sufficient pressure to maintain a continuous, non-fluctuating spray capable of reaching the extremities of the seeding area with the pump unit located on roadways. Sufficient hose shall be provided to reach areas not practical to seed from a hydro-seeder operating from a roadway.

When bonded fiber matrix is specified as hydroseeding mulch, the slurry of seed, fertilizer, lime, mulch, and water shall be applied in two separate applications. The second slurry application shall be applied as soon as possible after the first, but with sufficient time between applications such that sloughing does not occur. The second slurry shall be applied in a different spraying direction than the first application.

2. Hand Broadcasting Methods - Hand broadcasting shall only be allowed for small areas and shall be subject to acceptance by Doyon Utilities’ Authorized Representative. Hand broadcasting shall be by means of portable hand operated mechanical spreaders. Application rates for seed, fertilizer, and lime
