<br /> <br />of some soils at the Pikeview Quarry. The samples were collected. in <br />• Tract C and Tract B and were of natural soils rather than spoils. The <br />analysis, done by the Soil Testing Laboratory at Colorado State <br />University, shows the soils were little different from the spoil samples <br />collected and analyzed by the Lincoln Devore Testing Laboratory. The <br />primary difference was a higher organic matter content in the soil. <br />Nutritionally, the CSU analysis recommended 20 lbs/acre of <br />nitrogen and 60 to 80 lbs/acre of phosphorous. Because these analyses <br />Caere done of soil and not spoil the nitrogen supplement to be used will <br />be like the other quarries, that is, 40 lbs/acre of nitrogen. This <br />will be done because the spoil is generally much less deficient in <br />nitrogen than the soils. The phosphorous addition will be at SO lbs/acre. <br />The resulting material will be a gravelly sandy loam with a pH <br />• of between 8.0 and 8.5 and a conductivity less than 1 mmoh/cm. It will <br />have about a 50 to 60~ content of less than 2 mm sized particles and a <br />silt/clay content of approximately 20~. This material will be moderately <br />permeable and the erosion hazard potential will be moderate to high <br />before erosion control measures are implemented. The material will be <br />fully capable of supporting grass growth of the species recommended and <br />where deeper soil exists will favor and support deep rocted plants. <br />The STS map unit is a soil derived from the Pikes Peak granite. <br />It is placed, by the S.C.S., in the Kutler-Broadmoor Complex and <br />characteristically supports conifer forests. <br />The series that form this complex are quite similar in most <br />respects and thereby are usually considered a complex. The only clear <br />distinction is that the R:utler usually supports grasses and shrubs and <br />• the Broadmoor sunports conifer forests. Typically they are up to about <br />P-I-3 <br />
