applied before, or at the time of, seeding. If necessary, full fertilization will be applied after
<br />emergence. However, any fertilization done following seeding should be done using a method
<br />that does not cause large scale disturbance of the surface. Fertilizer mixtures will be based upon
<br />soil tests made on samples taken from re- soiled areas prior to seeding.
<br />The seed mixture for the proposed permit area is the same as for the current permitted Tucker Pit
<br />(M -1980 -002) site and is listed below.

<br />Rates are for drill seeding. If broadcast seeding is used, double
<br />seeding rates.
<br />If a significant invasion of noxious weeds occurs after seeding, the weeds will be mowed before
<br />they can go to seed. The areas will be mowed periodically for additional control as needed.
<br />Mechanical control will be used as a first priority. Chemical methods will only be used if no
<br />other alternative produces acceptable results.
<br />Periodic inspection for noxious weeds, at least once a year early in the season, will be done. The
<br />weed inspection will search for not only the expected species but also any new List A or B
<br />species introductions. It is likely that non - noxious and List C species will also be found. Non -
<br />noxious weeds, which are often native invaders, do not need to be controlled, but if the
<br />population of a List C species is controllable then it will be included in the control program.
<br />List C noxious species are problematic but are usually not as serious as List B species. List B
<br />species in Colorado and utilized for Weld County weed management include: Absinth
<br />wormwood, Black henbane, Bouncingbet, Bull thistle, Canada thistle, Chinese clematis,
<br />Common tansy, Common teasel, Corn chamomile, Cutleaf teasel, Dalmatian toadflax, Dame's
<br />rocket, Diffuse knapweed, Eurasian watermilfoil, Hoary cress, Houndstongue, Jointed goatgrass,
<br />Leafy spurge, Mayweed chamomile, Moth mullein, Musk thistle, Oxeye daisy, Perennial
<br />pepperweed, Plumeless thistle, Quackgrass, Russian knapweed, Russian - olive, Salt cedar,
<br />Scentless chamomile, Scotch thistle, Spotted knapweed, Spurred anoda, Sulfur cinquefoil,
<br />Venice mallow, Wild caraway, Yellow nutsedge, and Yellow toadflax.
<br />All List A species must be eradicated by law. These weeds include African rue, Bohemian
<br />knotweed, Camelthorn, Common crupina, Cypress spurge, Dyer's woad, Elongated mustard,
<br />Giant knotweed, Giant salvinia, Hydrilla, Japanese knotweed, meadow knapweed, Mediterranean
<br />sage, Medusahead, Myrtle spurge, Orange hawkweed, Purple loosestrife, Rush skeletonweed,
