	As outlined in Sec 805, it is MoDOT’s intention to plant cool season and warm season grasses within the right-of-way. Cool season grasses provide a dense stand of grasses in a reduced time over warm season grasses. Cool season mixes grow better in the early spring and late fall when soil and air temperatures are cooler. Warm season grasses take a bit longer to establish growth, but they provide deep root systems that require less moisture, fertilizer, and pesticides.

	Job special provisions will no longer be required for seeding mixes.

	'''Cool Season Grasses –''' The preferred time to seed cool season grasses is outlined in Sec 805.3. Full seeding periods include the months of December through May, August, and September. During these months, all lime, fertilizer, seed, and mulch shall be applied. When seeding of cool season grasses occurs during the months of June, July, October, or November, partial fertilizer and seed shall be applied at the rates specified in Sec 805.3. Overseeding, to include the specified rates of seed and fertilizer, shall be applied during the months of August, September, December, January, or February. Lime will be applied at the full rate during the initial installation and will not require additional application at the time of overseeding. Likewise, additional mulch will not be required for overseeding, unless there are bare spots that require correction, as directed by the engineer. No additional payment for mulch will be made for any areas of correction.		'''Cool Season Grasses –''' The preferred time to seed cool season grasses is outlined in Sec 805.3.

	In addition to requirements of Missouri Seed Law, the specifications list minimum percentages of purity and germination, which govern unless otherwise permitted by the engineer. Intent of this specification is that seed will not be furnished with less than the percent purity and/ or germination required. However, requests may be received for permission to apply increased quantities of seed deficient in purity and/or germination to compensate for deficiency. In such cases, the resident engineer should consult with the Roadside Management Supervisor, Maintenance, (573) 751-8647, for approval and revised application rate. This procedure will not normally be allowed as it is intended that the contractor furnish seed of specified quality. If approval is granted, the revised rate will not give credit for any excess purity and/or germination that may exist. Seed may be accepted on the basis of label if the data conforms to contract requirements and registered seed technologists or the seed company, provides proper certification verifying in detail the analysis that appears on the label.
