Table 6-1-3 (Cont.) <br /> Footnotes: <br /> 9 <br /> Specific level depends upon clay mineralogy, soil texture, and saturation percentage <br /> according to Dollhopf et al . (1985) and MDSL (1983). <br /> 10 <br /> These values are similar to those recommended by Barrett et al . (1980), MDSL (1983), <br /> WDEQ (1985), USDA (1983), USDI-OSMRE (1985a), Schafer (1979, 1980), and USDI-BLM <br /> (1977). <br /> 11 <br /> Proposed by USDI-OSMRE (1985a). <br /> 12 These values are similar to those recommended by Barrett et al . (1980), MDSL (1983), <br /> Schafer (1979, 1980), USDI-OSMRE (1985a), and USDI-BLM (1977). USDA (1979) proposes <br /> 12. <br /> 13 <br /> Proposed by USDI-OSMRE (1985a). <br /> 14 The specific percentage of clay or sand will depend upon clay mineralogy, size of sand <br /> fraction, and saturation percentage. Abbreviations includes - sand, M-Co s - medium <br /> to coarse sand, is - loamy sand, sl - sandy loam, 1 - loam, si - silt, sil - silt <br /> loam, sicl - silty clay loam, sic - silty clay, cl - clay loam, sc - sandy clay, c - <br /> clay. <br /> 15 <br /> Very similar to recommendations by Schafer (1979, 1980), USDI-OSMRE (1985a), USDA <br /> (1983), WDEQ (1985), and USDA (1979). <br /> 16 <br /> Similar to USDI-OSMRE (1985a), USDA (1979) proposes greater than 60% clay. <br /> 17 Recommended by MDSL (1983), WDEQ (1985), and USDI-OSMRE (1985a). Schafer (1979, 1980) <br /> proposes 8. The lower limit recommended by Barth et al . (1981). <br /> 18 <br /> The actual maximum acceptable molybdenum concentration will depend upon the plant <br /> species proposed in the revegetation plan seed mix and their potential for molybdenum <br /> accumulation. The depth of replaced topsoil must also be evaluated. <br /> 19 <br /> Recommended by MDSL (1983). Barth et al . (1981) and Sutton et al . (1981) recommend <br /> 2.0. <br /> 20 <br /> Presented by Peabody (1987) from data extrapolated from Neuman and Munshower (1983). <br /> A value of 2 assumes 100% legumes with 2 feet of topsoil while a value of 8 assumes <br /> 100% grasses with 2 feet of topsoil. An upper limit of 1.0 is proposed by MDSL (1983) <br /> and WDEQ (1985). A limit of 0.85 is proposed by Neuman and Munshower (1983) for a <br /> site with no topsoil. <br /> 21 <br /> Proposed by MDSL (1983) and WDEQ (1985). <br /> 22 <br /> Recommended by USDI-OSMRE (1985a); Schafer (1979, 1980) proposed 2.0. <br /> 23 <br /> Proposed by WDEQ (1985). The lower limit proposed by Sutton et al . (1981). <br /> 24 <br /> Recommended by Singleton and Barker (1980). <br /> 6-1-29 Revised 04/11/88 <br />
