Box 316 <br />Pueblo, CO 81002 <br />Dear Mr. Zeeb: <br />In response to our telephone conservation May 11, 1981, I am enclosing the <br />following information on the soils tested at the Maxwell and Allen mines. <br />The soil type at the Allen mine was determined to be Table Mountain loam. <br />The soil type at the Maxwell mine was determined to be Noden. These soils <br />do not have any restrictions of plant growth. <br />In the previous tests at the Allen mine (4 sample sites), I stated that the <br />soil had two horizons that should be stockpiled separately. The A and B <br />horizons were both high in organic matter and ranged from 20 to d0 inches <br />thick. They do not require separation. The C horizon was low in organic <br />matter and slightly calcareous. Both horizons are good growth mediums having <br />_ Low SAR, Electrical conductivity, and calcium carbonate equivalents. The <br />A and B horizons are better growth mediums due to the high organic matter <br />content. <br />The sample taken at the Maxwell mine had two distinct horizons, A and B, <br />~.vhich need to be separated. The A horizon was high in organic matter, had <br />a neutral ph, and was low in solvable salts (SAR). IC is an excellent soil <br />for reestablishing vegetation. The B horizon is slightly alkaline and non- <br />saline. It does not have the high organic matter content so would not be <br />quite as good a growth medium. Other than low organic matter content, there <br />are not any other problems associated with this soil, i.e., it has low salt <br />content and low electrical conductivity. tJith proper fertilization, the C <br />horizon would be productive with almost any type of vegetation. <br />In response to your request for soils information in Apache Canyon, I am <br />sorry to say that it is not available at this time and cannot be determined <br />unt_1 the later part of July due to a 6-8 week work detail at Salida I oust <br />attend. I will determine the soil at that tine. It has been ny exper:enca <br />h o~:ie ver, 'that the soils in that area, do not have any problems ~sith salt er <br />carbonates. The only hazards the soils .right have are steepness of slope <br />and shallow depth to bedrock in areas away from the canyon floor. <br />If you have any questions or need further information please let me know. <br />Sincerely, <br />Lee A.
