2.04.9 • RESPONSE continued important since the organic matter supplies most of the nitrogen available to vegetation. The A horizon contains the highest amount of organic matter. Concentrations of organic matter range from 1.4-8.6$. The B horizon contains 2-4$ less organic matter than the A horizons. Available phosphorus ranges from 4-34 ppm. The highest concentrations are in the A horizons and generally get progressively less down through the profile. Available potassium ranges from 110-220 ppm. There isn't any pattern to the distribution of the potassium in any of the soil profiles. The saturation ranges from 46.9-63.2$ depending on the texture. Generally, the higher the amount of clay the higher the percentage of saturation. The sodium adsorption ratio (SAR) ranges from 0.8-2.6. These values indicate that sodium will not be a potential problem. • The results from soil samples taken on the north side of County Road 53 are shown in Table 4 and the soil descriptions are located in the appendix. The pH ranged from 5.8-7.3. The slightly acid soils are located in the B horizon of several Routt series soils. The lower pH indicates a possible leaching out of carbonates. This does not pose any problems to reclamation since sufficient high quality A horizon is present for use in reclamation. The electrical conductivity ranges from 0.14-0.66. These values are very low and wouldn't affect even the most sensitive plants. The organic matter ranges from 0.4-2.5$. The A horizon contains the highest amounts of organic matter. Available phosphorus ranged from 1-40 ppm. The highest con- centrations were found in the A horizon which will be used for reclamation. The B horizon contains much smaller concen- trations . Available sodium was found to range from 0.14-0.32 meg/1. These concentrations are low and will not be any problem as far as revegetation is concerned. Available calcium ranged from
