14. The specific percentage of clay or sand will depend upon clay mineralogy, size of sand fraction, <br />• and saturation percentage. Abbreviations include s -sand, M-Cos -medium to coarse sand, s - <br />loamysand, Iayssandyloam, Iloam, si -silt, sil -silt loam, sicl -silty clay loerri, sic -silly day, <br />cl -clay loam, sc -sandy clay, c -clay. <br />15. Very similar to recommendations by Schafer (1979, 1980), USDI-OSMRE (1985a), USDA <br />(1983), WDEQ (1985), and USDA (1979). <br />16. Similar to USDI-OSMRE (1985a), USDA (1979) proposes greater than 60% clay. <br />17. Recommended by MDSL (1983), WDEO (1985), and USDI-OSMRE (1985a). Schafer (1979, <br />1980) proposes 8. The lower limit recommended by Barth et al. (1981). <br />18. The actual maximum acceptable molybdenum concentration will depend upon the plant species <br />proposed in the revegetation plan seed mix and their potential for molybdenum aocumulatan. The <br />depth of replaced topsoil must also be evaluated. <br />19. Reommended by MDSL (1983). Barth et al. (1981) and Sutton et al. (1981) recommend <br />2.0. <br />• 20. Presented by Peabody (1987)from data extrapolated from Neuman and Munshower (1983). Avalue <br />of 2 assumes 100% legumes with 2 feet of topsoil while a value of 8 assumes 100% grasses with 2 <br />feet of topsoil. An upper limit of t.0 is proposed by MDSL (1983) and WDEQ (1985). A limit of 0.85 <br />is proposed by Neuman and Munshower (1983) for a site with no topsoil. <br />21. Proposed by MDSL (1983) and WDEQ (1985). <br />22. Recommended by USDI-OSMRE (1985a); Schafer (1979, 1980) proposed 2.0. <br />23. Proposed by WDEQ (1985). The lower limit proposed by Sutton et al. (1981). <br />24. Recommended by Singleton and Barker (1980). <br />25. This value proposed by Barth et al. (1981). <br />26. This value is supported by WDEQ (1985), Smith (1974), and Sutton et al. (1981). Units are tons of <br />CaCO3 equivalenU1000 tons. <br />27. These values supported by Sutton et al. (1981) and Lindsay and Novel (1978). Schafer (1 980 ) <br />• proposes 60. <br />REVISED Auguat 2006 2.D4.6-32 <br />
