the chemistry of the patent material at this location, a c<~ndition • induced during the formation of the limestone itself. It must be pointed out that these tests were not of native soil of which virtually none exists, but was of a material essentially representative of the plant growth medium to be used in reclamation. In late 1979 the Lincoln DeVore Testing Laboratory surveyed the soils of the present site. The results of this survey are presented in the Soils and Bedrock Map of this exhibit and are explained in Tables 1, 2, and 3 of this exhibit. Most of the quarry is covered with a gravelly loam or gravelly sandy loam with about a 178 silt/clay content and about 50 to 608 less than 2 mm sized materials. Such a composition, although a bit droughty, should be capable of supporting the reclamation grasses as well as deep rooted plants which the coarse materials will favor to a large extent. • The eventual material to be used on the terraces will be a gravelly sandy loam a little coarser than the fill material, but still containing SO to 608 particles less than 2 mm in diameter. Silt/clay composition should be about 208. The pH of this medium will be between 8.0 and 8.5 and conductivity less than 1 mmoh/cm. Using this medium in reclamation should be fully capable of producing adequate plant growth. These materials are little different in their physical and chemical characteristics than the native soils derived from the limestone and forming the Paunsaugunt Series. The development of vegetation will no doubt be slow at first but should develop much more rapidly after the first few years of growth. This will also add organic matter to the soil and will make it even better. • Irrigation to equalize deficient precipitation would signi- ficantly affect the rate of development producing a more dense growth much faster. However, such growth would also require more nutrients, S-I-3
