VEGETATIVE SPECIFICATION

275. SEEDING

This work consists of furnishing seed, labor, equipment, and planting seed on designated areas.

2. MATERIALS

All seed shall meet the requirements of the specifications found in the Oklahoma Seed Law which specifies the kind and amount of weed seed permitted, the requirements for a current analysis report, labeling of all seed to show its purity, germination, date of last germination test, and weed seed content.

For seed shipped across state lines, the germination test is valid for 5 months after the end of the month the test was made.

For seed purchased during the valid period of the germination test, the analysis report may be considered current for the full seeding period in effect at the time of purchase. If the seed is to be planted during a later seeding season, a new germination test should be obtained.

All seed shall have a Pure Live Seed (PLS) determination. PLS is computed by adding the percent germination to the percent hard seed, multiplying by the percent purity and dividing by 100.

The seed shall be uniformly applied at the rate and dates specified in Section 6, Construction

Details.

Inoculants shall be the appropriate commercial culture of nitrogen-fixing bacteria prepared specifically for the legume to be inoculated. The inoculants shall be used prior to the expiration date stamped on the package and stored in a cool place until used.

3. SITE PREPARATION

Unless otherwise specified in Section 6, Construction Details, a smooth, firm seedbed, free of competing vegetation, shall be prepared to a minimum depth of 4 inches, deeper if needed to break up a restrictive compacted layer of soil. The site shall be suitable for maintenance with farm equipment. A tractor or truck shall be used to hold equipment on 3:1 slopes or steeper.

4. PLANTING

The seed shall be drilled and firmly anchored into mineral soil. Seed shall be planted 1/4 to 3/4 inch deep and drilled on the approximate contour. Packing shall not be required where hay mulch is to be applied and anchored immediately following seeding. Small areas not accessible to the grass drill can be seeded by hand or other suitable equipment as long as the soil is firmed over the seed.

NRCS-1/06 275-1

5. MEASUREMENT AND PAYMENT

For items of work for which specific unit prices are established in the contract, seeding will be measured to the nearest one-tenth acre. Payment for seeding will be made at the contract unit price.

Such payment will constitute full compensation for all labor, materials, equipment and all other items necessary and incidental to the performance of the work.

Compensation for any item of work described in the contract but not listed in the bid schedule will be included in the payment for the item of work to which it is made subsidiary. Such items and the items to which they are made subsidiary are identified in Section 6 of this specification.
