Clay 5% - 15% Sand 40% - 60% Silt 35% - 55% Organic Matter 2% - 4% pH Range 5.6 - 6.5

01035.11 Seed - Furnish seed meeting the following requirements:

(a) Label - Deliver all seed in standard, sealed containers. Label each container with the following:

Special Provisions - Job #900647 Page 13

• The kind and variety of each seed of 5 percent or more in a mixture, by weight. Be sure that seed mix labels include the words "mixture" or "mixed seed" when the seed is a mixture

• The country or state where the seed is grown

• The lot number or other lot identification

• The total percentage, by weight, of other crop seed

• The total percentage, by weight, of weed seed

• The total percentage, by weight, of inert matter

• Statement of "No Noxious (weed) Found"

• For each named seed:

• Percentage of germination

• Percentage of hard (non-living) seed, if more than 1 percent

• Percent of PLS for each kind of seed

• Percent and kind of other crop

• Month and year of seed test

• Net weight of contents

• Name and address of seed labeler or seller

• Origin for each seed (state or foreign country)

• If seed inoculant is used, the claimed date that inoculant effectiveness ends

• For treated seeds (if any):

• Statement that the seeds have been treated

• Name of all chemical used in the treatment

• Description process used in the treatment

• Warning statement for all residual chemicals used

• Net weight of each container

• For seeds listed as native, date and location of collection of source (first generation) seed

• For native seeds specified to be collected for direct use on a project, label containers with the date and location of collection sites for each seed species

(b) Quality - Furnish seed meeting the following requirements:

• The seed and labeling complies with Oregon Seed Law and Federal Seed Act.

• The seed has been tested within 18 months of the planting date.

• The seed is not sprouted, moldy, or showing evidence of having been wet or otherwise damaged.

• The seed is labeled as "Oregon Certified Seed" or the equivalent from another state when identified in the Special Provisions. Information about certified seed is available from County Extension Offices, Oregon State University, and the Oregon Department of Agriculture.

(c) Pure Live Seed - Obtain the amount of seed to apply by using the purity and germination percentages from the label on actual bags of seed to be used on the Project.

To calculate the amount of seed to be applied:

• Obtain the PLS factor - Multiply the seed label germination percentage times the seed label purity percentage.

• Divide the specified PLS rate by the PLS factor.

Example: A PLS seeding rate of 10 pounds per acre is specified. The seed label shows a purity of 80 percent and germination is 90 percent. After converting percentages to decimals, Special Provisions - Job #900647 Page 14

0.80 x 0.90 equals a factor of 0.72. The specified PLS rate, 10 pounds per acre, divided by the factor of 0.72 equals 13.88. In order to meet a PLS seeding rate of 10 pounds per acre, about 14 pounds of seed needs to be applied per acre. For a seed mix, make this calculation for every seed to obtain the total amount to be applied.

(d) Inspection - Each lot of seed is subject to inspection upon delivery to the Project. Seed that is not labeled or that does not conform to the Specifications will be rejected and shall be replaced at no additional cost to the Agency.
