Apply the seed at a minimum rate of 40 pounds per acre. <br />2. Drilling Seeding - If the drill seeding method is used, the drill shall be regulated <br />to uniformly distribute the seed at the rate specified herein on the areas to be <br />seeded. Where possible to safely operate equipment, as approved by the <br />Engineer, drilling shall be down crosswise to the general slope.

Hand Broadcasting -Seed application may be performed by using any <br />approved hand broadcaster or by broadcasting the seed by hand from a <br />sack or other suitable container. Whichever means is used, the seed <br />shall be uniformly applied at the rates specified herein. Immediately <br />after broadcasting the seed and fertilizer, they shall be properly covered <br />with soil to the depths prescribed above by means of a hand rake or <br />float. Covering broadcast seed by dragging a log chain or similar devise <br />will not be permitted. <br />C. Fertilizer -The Contractor shall furnish and apply uniformly commercial fertilizer <br />at the minimum rate of 50 pounds per acre. Fertilizer may be applied prior to <br />seeding by suitable mechanical spreaders, blowers, or hydraulic equipment. <br />Fertilizer may also be applied when seeding as specified above.
