CECs at 7.9 and 8.7 cmol/kg, respectively. Base saturation ranged from 39% to 100% and was<br />

similar <strong>for</strong> three <strong>of</strong> the six sites. While having one <strong>of</strong> the highest CECs, Parkersburg had the<br />

lowest base saturation and this is due to much <strong>of</strong> the original native topsoil being replaced on this<br />

site, which contained higher clay contents and was more acidic. Of the extractable bases, Na and<br />

K were similar <strong>for</strong> all sites, while Ca and Mg varied considerably among the different sites.<br />

Calcium ranged from 2.4 cmol/kg to 18.2 cmol/kg, and Mg ranged from 0.2 cmol/kg to 1.6<br />

cmol/kg. Elkins and <strong>West</strong>on had the highest Ca concentrations and Baker had the lowest.<br />

Parkersburg and <strong>West</strong>on had the highest Mg concentrations and Hazelton the lowest.<br />

All sites had substantial soil organic matter, and soil organic matter was significantly<br />

correlated with total plant cover. <strong>The</strong> <strong>West</strong>on and Buckhannon sites had the highest amount <strong>of</strong><br />

organic matter (>6%). This most likely reflects the age and productivity <strong>of</strong> these sites as they are<br />

the oldest and there<strong>for</strong>e have had more time to accumulate organic matter. Values obtained <strong>for</strong><br />

total carbon correlated with soil organic matter. <strong>The</strong> <strong>West</strong>on and Buckhannon sites had the<br />

highest total carbon concentrations and Baker the lowest. Total carbon showed a trend to<br />

increase total plant cover, while total percent nitrogen tended to increase seeded native plant<br />

cover. <strong>The</strong> Elkins site had a higher nitrogen concentration (0.22 %) compared to the other sites<br />

(three times higher than <strong>West</strong>on and seven times higher than Baker, Hazelton, Parkersburg, and<br />

Buckhannon) and this correlates to a significantly higher seeded native plant cover (10% versus<br />

0-3%). <strong>The</strong> higher nitrogen concentrations at this site could relate to the lack <strong>of</strong> total cover<br />

(fewer plants available to remove nitrogen from soil) and to the lack <strong>of</strong> leaching as evidenced by<br />

the increased EC. Phosphorus concentrations were low at all sites. <strong>The</strong> Baker and Parkersburg<br />

sites had concentrations three times higher than the other sites. Copper and manganese<br />

concentrations were sufficient <strong>for</strong> plant growth at all sites. Zinc concentrations ranged from 2.2<br />

to 12.5 mg/L and were significantly correlated to total plant cover but not to seeded native cover.<br />

Total bulk density (Table 24) was variable across sites, ranging from 1.2 to 1.9 g/cm 3 .<br />

Higher bulk densities were significantly correlated to decreased total cover but no correlation<br />

was found between bulk density and seeded native cover. Adjusted bulk density (
