Fertilizer shall be incorporated into the soil if <br />possible. Incorporation may be as part of the seedbed p~p~ration <br />or as part of the seeding operation. <br /> <br />The fertilizer shall contain a minimum of 16% nitrogen, 20% <br />available phosphoric acid, 0% water soluble potash and 15% sulfur. <br />It shall be uniform in composition, dry and free flowing, pelleted <br />or granular. <br /> <br />All fertilizer shall be delivered in unbroken or unopened <br />containers, labeled in accordance with the applicable state <br />regulations, and bearing the warranty of the producer for the <br />grade furnished. <br /> <br />Ce <br /> <br />Mulch.

Seed shall not remain in the slurry longer <br />than 30 minutes. The slurry shall contain the required fertilizer and <br />shall also contain wood fiber to the applied at the rate of 2,000 pounds <br />of wood fiber per acre. <br /> <br />The water used shall be potable water. <br /> <br />The slurry shall be continuously mixed and shall be mixed for at least 5 <br />minutes after the last addition before application starts.
