availability of phosphorous to plants. Additionally, it will be difficult <br />• to properly incorporate applied phosphorus into the soil over much <br />of the reclaimed sites. Seed mixes are comprised of mostly native <br />species. These native species and the few introduced species are <br />adapted to low fertility environments. <br />If at any time fertilization of a site is deemed necessary, the type <br />and rate of application will be based on fertility tests. Tests will <br />use an ammonium bicarbonate - DTPA extract method for pH, <br />electrical conductivity, nitrate-nitrogen, phosphorus, iron, <br />potassium, manganese, zinc and copper and a water extract for <br />sodium, calcium and magnesium. <br />(viii) The North Decline was graded in the spring of 1992 and seeded <br />with the final seed mix in the fall of 1992. Visual inspections of <br />the site during 1993 through 1995 indicated poor revegetation <br />success for grasses and fortis and a major invasion of cheat <br />grass. The shrubs did well on portions of the site. There is no <br />hurry for bond release on the site and the current vegetative cover <br />is adequate for erosion control, therefore, control of cheatgrass is <br />not an immediate concern. Control of cheatgrass and reseeding <br />will be done according to plans approved by the Division at some <br />later date. Approximately 2.5 acres was ripped on 2' intervals to <br />a depth of 18" in the fall of 1996 and broadcast seeded on the <br />rough ripped surtace. This treatment will be evaluated as a <br />possible treatment for the entire site. <br />Regrading and Stabilization of Rills and Gullies <br />Reclaimed areas will be monitored for rills and gullies in the spring <br />14-27 (Rev. 12/16/96) <br />
