In addition, Yoast field and laboratory soil data will be used, in conjunction with current SCS <br />• Homographs, to quantitatively determine the "K" factor and "WEG"group number (class) of study <br />area soils. Correlation of site-specific soils with SCS soil series allows for comparison of these <br />site-specific "K" factors (used in water erosion hazard evaluations) and "WEG" group numbers <br />(wind erodibility class for wind erosion hazard evaluation), generated from the Yoast soil data <br />base, with established "K" factor and "WEG" numbers individually generated by SCS for each <br />official soil series. <br />3.4 Soil Laboratory Analysis <br />Samples collected in the field were analyzed in the laboratory in accordance with CDMG- <br />approved procedures for topsoil analyses as outlined in Table 1. The information presented in <br />this table is a synthesis of material from the approved scope-of-work and Colorado State <br />University's Soil Testing Laboratory standard procedures for soil analysis. <br />Parameters analyzed for this project include: <br />• pH (saturated paste) <br />• Electrical Conductivity (EC of saturated paste extract) <br />• Saturation Percent <br />• Texture (including very fine sand) <br />• Organic Matter Percent <br />• Rock Fragment Percent (field sieve# 10 determination) <br />Water Soluble Ca, Mg, Na (meq/I) <br />• Sodium Adsorption Ratio (SAR) <br />• Calcium Carbonate Equivalent Percent <br />Fertility assessments were not necessary at this time. During the reclamation phase (topsoiling), <br />fertility assessments may be requested by agency personnel. <br />• <br />13 <br />
