~~ Fourteen soil sapplas wars taken Tram the area to ba disturbed by • the Sanborn Creek Mine on November 2, 1990, and subjected to chemical and physical analyses. Twalva o! the samples ware taken from 4 pits which ware dug on the site for soil eamplinq (9 from various horizons which wars distinctive in the pits, and 7 as composites o! depths ieyths-pi.~ts), and 1 wara.takan from adjacent areas to the pits (sae'~xhibiz s-010). The arse o! most soil available !or'revegetation and plant growth is a small alluvial plain formed under cliffs which rim the area. The area is composed o! ltancos shale topped by various thicknesses o! sandstone with small deposits o! granite and gneiss, possibly washed in from higher terrain. The small alluvial plain was occupied by several houses at one time. Other leaser areas o! soil may be found in the area, but era so rock- strewn that recovery of soil from them would not ba practical. The soil horizons era thickest in the western most region of the plain area, and grade to thinner in the eastern region (su table 1). In general, an average depth of soil in the pits is about 1 Teat. ~ The soil is o! axcallsnt quality (tables 2 and 1), although the fertility with respect to nitrogen and phosphorus is low. Potassium and the micronutriants era present in sufficient quantities to support adequate plant growth. Thera is soma salinity present, but not in quantities so as to limit plant growth. The sodium adsorption ratios era approximately the value of 4.0 which would indicate a low sodium hazard in Chia soil. pH's o! the soil era around neutrality, an inherent feature of most soils of this altitude; this is a desireable value. The organic matter content o! the soils is quits high which may ba due to the abundance of coal in the immediate vicinity. RECOIQSIIfDATZONS r The soil should be stockpiled from the alluvial plain area and used !or ravegetation purposes as Headed. adjacent areas o! the disturbed area are too rocky for proper revegatation use; hovaver, theta should be sufficient soil in the alluvial area for use. The horizons below the designated horizons era too rocky !or use also. Tha soil overlies sandstone and Mancos shale. J1n addition o! fertilizer may be helpful in establishing new vegetative growth. Therefore, the following fertilizer additions are recommended: Phosphorus: 40 pounds per acre. This may be added as 0-45-0 (4S= phosphate, Calcium phosphate) at the rata o! 90 pounds par acre. • 2.04 - 67~
