1999 Soil Sampling: Seneca Mine, Hayden Colorado <br /> Phosphorous <br />• Nitrous Nitrogen <br /> Potassium <br />' Zinc <br /> Iron <br /> Manganese <br /> Copper <br /> Sodium Adsorption Ratio <br />' Organic Matter <br /> pH <br /> Electrical conductivity <br />' Percent Saturation <br />Vegetation- Vegetation was observed qualitatively for vigor, color, growth form, and <br />overall vegetative appearance both above and below ground. Above ground plants <br />were observed for ground cover density, basal area, growth form vigor, color and <br />' height. Below ground plant roots were observed for vigor, abundance, size, <br />distribution, and depth of penetration. A general site photo was taken at each <br />sample location along with 2 photos of the ground taken from a height of 6 feet at a <br />' 60 degree angle to the ground. <br />Results <br />' ~ Results for the Seneca II and Seneca II-W follow: <br />' Seneca II <br /> 2 sites were sampled on approximately 50 acres of land, Field descriptions are <br /> located in Appendix IV and lab data is located in Appendix II. <br />t Topsoil- Topsoil in both sample pits classifies as suitable topsoil (Appendix III, <br />The results follow: <br />Table-2) <br /> . <br /> Depth- The average depth of topsoil is 11 inches (.9 feet). Depth of topsoil <br />' ranges 10 to 12 inches (.8 to 1.0 feet). The topsoil in both sample pits <br /> consisted of two horizons. The upper horizon averages 5 inches of thickness <br /> and ranges in depth from 5 to 5 inches in thickness. The lower topsoil horizon <br />' averages 6 inches in thickness and ranges from 5 to 7 inches in thickness. <br /> The difference in horizons is due to structure and dry and moist consistence <br />' discussed below. All other characteristics between horizons are the same. <br /> Textures- Textures are looms. Clay content averages 25 percent and ranges <br /> 22 to 27 percent, sand content averages 40 percent and ranges 39 to 40 <br />' percent. Silt content averages 35 percent and ranges 34 to 38 percent. <br /> <br /> <br /> Page 5 of 11 <br />' 09/23/99 , <br />
