TABLE 2.04.9-2 <br />CRITERIA FOR EVALUATING SOIL SUITABILITY <br />PARAMETER-UNITS <br />PH <br />Conductivity (mmhos/cm) <br />Saturation percentage (%) <br />Sodium adsorption ratio3 <br />Calcium carbonate percentage <br />Selenium (ppm) <br />Particle size" <br />Coarse fragments (%) <br /> <br />THRESHOLD SUITABILITY LEVEL' <br /><6.1->7.8 <br />4.02 <br />>80% <br /><25% <br />>4 <br />>15% <br />>2 PPm <br />All soil textures except: <br />s, Is, sc, sic, c <br />15%5 <br />' The threshold levels are to be used as a guide in evaluating the suitability of a soil material for <br />reclamation. An evaluation should take into account the "total system". Interactive parameters <br />may either nullify or verify the significance of a potential problem. <br />2 The actual maximum acceptable salt level will depend on the plant species proposed in the <br />revegetation plan and the potential for upward salt movement. <br />3 Specific level depends upon clay mineralogy, soil texture, and saturation percentage according <br />to Dollhopf et al., 1983. <br />"The specific percentage of clay or sand allowed will depend upon clay mineralogy, organic <br />matter content, consistence, soil lift, spoil characteristics, and size of sand fraction. <br />• (REVISEDZ00) 2.04.9-t0 <br />
