These <br />two soils are very pour sources of topsoil due mainly to the thin surface layer <br />and the large stones and fragmented material on the surface and in tlTe suhsoil. <br />The only available soils in the area that. I wouh~ recommend for saying as a <br />suitable plant medium would he from the Satanta Series. "Phis soil is located <br />on the terrace tops, the amount of suitable top soil decreases nearer the terrace <br />edges. <br />In determining the average depth of topsoil that could he used, 30" over the <br />Satanta Series area would be a realistic Figure to use in determining topsoil <br />yardages. <br />Si eercly~~ , <br />0 The Swl fnnvw valion Service <br />U + nn aqn n<Y nl IhP <br />Urnnrtmr..r o~ Pw enqurn <br />SCS-AS-1 <br />10~1A <br />
