matter ranges from 0.4-2.5$. The A horizon contains the highest amounts <br />of organic matter. Available phosphorus ranged from 1-40ppm. The <br />highest concentrations were found in the A horizon which will be used for <br />reclamation. The B horizon contains much smaller concentrations. <br />Available sodium was found to range from 0.14-0.32 meg/1. These con- <br />centrations are low and will not be any problem as far as revegetation is <br />concerned. Available calcium ranged from 0.82-4.44 meg/1. The highest <br />quantities of calcium are found in the A horizon of all three soil series. <br />Thus there appears to be more than enough plant available calcium for <br />reclamation. The magnesium content ranged from 0.21-0.93. The highest <br />concentrations are found in the A horizon. More than enough plant avail- <br />able magnesium seems to be present. The sodium adsorption ratio (SAR) <br />ranges from 0.11-0.49. These values are very low and won't pose any <br />problem in reclamation. The texture is variable through the profile. Most <br />of the soil profiles have day accumulations in the B horizon. The A <br />horizons appear to have been e]uviated. The texture in the A horizons <br />contain less clay and are more suitable for reclamation as far as physical <br />and chemical properties are concerned. <br />SUITABILITY OF SOIL HORIZONS FOR RECLAASATION <br />The soil test results for all the soil series indicate that the A horizon is <br />superior both physically and chemically as compared to the B horizon. The <br />major advantage of the A horizon is that it generally contains more organic <br />matter and phosphorus than the B horizon. Also the A horizon has better <br />soil structure than the B horizon. This structure is important to the. <br />percolation of water through the soil and thus influences the availability of <br />water to plants. <br />The quantity of topsoil at the site is sufficient for all reclaation needs. <br />The stripping depths are illustrated on the Soil Survey map located in the <br />appendix of this section. The Routt loam appears to be chemically and <br />physically superior when comparing soil series. The expected quantity of <br />topsoil available will be about 15 inches of high quality A horizon. The <br />resulting quality of redressed topsoil would have approximately the follow- <br />ing characteristics; it would be a dark brown silty clay loam with moderate <br />fine to medium subangular blocky structure. It would be slightly acid to <br />slightly alkaline, noncalcareous and have an organic matter content of <br />approximately 2-3$. <br />
