The upper 6-inches of soil has sufficient organic matter content to reduce consistency, structure, and compaction problems during topsoil handling. Therefore, a 6-inch soil salvage thickness is recommended.

All soil material below the mollic epipedon has unsuitable clay textures and very hard-very-f irm-very sticky-very plastic consistence. Suitable topsoil salvage is limited to the A and BA horizons. Therefore, a 9-inch soil salvage thickness is recommended.

The entire profile is suitable with no limiting factors. Therefore, the whole soil, until bedrock is encountered, is recommended for salvage. Therefore, a 48-inch topsoil salvage thickness is recommended. However, Coutis on slopes in excess of 45 percent (Map Unit 34F) is unsalvageable due to very steep slopes. • • •
