Additional irrigation's after July can be at the <br />discretion of the party responsible for reclamation. During the second <br />growing season, enough supplemental water should be applied so that <br />when combined with natural precipitation, two inches of moisture is <br />received per month during May, June and July.

All tillage, seeding, and crimping operations should be performed <br />across the slope when practical. <br />The area should be protected from grazing and trampling until the <br />seeding is well established. Normally at least two years of protection <br />is needed. <br />During seedling establishment, weeds may be controlled either by <br />mowing or by using an approved herbicide. Refer to the current <br />Colorado Pesticide Guide, Field Crops section, for herbicide <br />recommendations to control weeds in the grass seeding. <br />In addition to the above recommendations, the following information and guidelines <br />are available from the Natural Resources Conservation Service office: <br />- Colorado SCS Spec. #544: "Land Reconstruction, Currently Mined Land" <br />- Colorado SCS Spec. #484: "Mulching" <br />- Colorado SCS Spec. #342: "Critical Area Planting" <br />- Colorado SCS Spec. #572: "Spoil bank Spreading" <br />- Agronomy Technical Note #48: "Seeding Rates" <br />Marcus Clark <br />~CGLGLC ~~r~//C <br />Soil Conservationist <br />
