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 /> Based on recommendations from the Natural Resources Conservation Service, the seed mixture
<br /> for the proposed permit area is similar to, but expanded from, the current permitted Connell Carr
<br /> Pit (M-2014-001) reclamation seed mix. The recommended seed mixture for lands in the region
<br /> of the proposed permit area is listed below.
<br /> Revegetation Seed Mix
<br /> Rate
<br /> Species (lbs PLS/acre)
<br /> Wheatgrass,Western 4.80
<br /> Grama, Sideoats 1.82
<br /> Grama, Blue 0.50
<br /> Green needlegrass 1.92
<br /> Buffalograss (bur) 1.65
<br /> TOTAL 10.69
<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, but may not be
<br /> limited to: Absinth wormwood, Black henbane, Bouncingbet, Bull thistle, Canada thistle,
<br /> Chinese clematis, Common tansy, Common teasel, Corn chamomile, Cutleaf teasel, Dalmatian
<br /> toadflax, Dame's rocket, Diffuse knapweed, Eurasian watermilfoil, Hoary cress, Houndstongue,
<br /> Jointed goatgrass, Leafy spurge, Mayweed chamomile, Moth mullein, Musk thistle, Oxeye daisy,
<br /> Perennial pepperweed, Plumeless thistle, Quackgrass, Russian knapweed, Russian-olive, Salt
<br /> cedar, Scentless chamomile, Scotch thistle, Spotted knapweed, Spurred anoda, Sulfur cinquefoil,
<br /> Venice mallow, Wild caraway, Yellow nutsedge, and Yellow toadflax.
