2.6 IRRIGATION AND FERTILIZATION (CONY)
Dr. Ed Redeme at Colorado State University and Dr. Terry McLendon at the University of Texas at
EI Paso have conducted research in Colorado, Utah, Wyoming, Texas, and New Mexico on limiting
nitrogen to assist in accelerating secondary native plant succession and recovery. Their work has
shown that if native plant establishment and the reduction of weeds is the goal then available soil
nitrogen must be limited in the soil. Their recommendation for establishing native plants from
shrubs to grasses to grasses to fortis is to forgo the application of supplemental nitrogen, and in cases
where weed are a major or potential problem, tie-up the available soil nitrogen with an available
carbon source such as sugar.
OMLLC, therefore, does not propose any addition of supplemental nitrogen. Soil fertility analysis
may call for the addition of supplemental phosphorus. If supplemental phosphorus is called for
OMLLC will apply 50 to 751bs per acre of phosphorus fertilizer (I'z0~) to be incorporated to a depth
of 1-3 inches by mechanical means. This incorporation of the phosphate in the upper 3 inches of the
plant growth medium will assist with the establishment and the growth of the germinating species
during the critical early seedling development phases. There may be site-specific conditions (steep
slope areas for example) where the application of phosphorus may not be practical or possible for
safety, rockyorother site-specific reasons.
2.7 CONTROL OF WEEDS
This weed control plan is concerned with the control of a wide variety of noxious weeds, thistles, etc.
located on mine disturbance areas.
The Delta County Noxious Weed website and personnel have been consulted regarding a Noxious
Weed Program Disturbed areas, topsoil stockpiles and reclaimed/seeded areas could be invaded by
the following noxious weed species with control afforded bythe described techniques.
Musk, Scotch Thistles, Burdock, Houndstongue, Tamarisk, Puncturevine - Controlled by
Banvel/2,4-D mixture, Curtail or Redeem Herbicides and non-ionic surfactant applied in spring or
early sutrur~er.
