eh <br />ESPEY, HUSTON 6 ASSOCIATES, INC. <br />• <br />Competing Series: These soils closely resemble the soils of the Thayne <br />series but differ in having hues redder than IOYR. They differ from the <br />Osmund series in having distinct ca horizons and in being calcareous at a <br />shallower depth. They differ from the Border series in lacking a textural <br />B2t horizon. They differ from the Woosley series in having redder hues, <br />in lacking a B2t horizon and in being more gravelly. <br />Typical Pedon: Redthayne soils consist of gravelly loam. <br />Al 0 to 5 inches; grayish brown (10YR5/2 dry) to very dazk greyish <br />brown (10YR3/2 moist) gravelly loam; strong very fine granulaz <br />structure; soft dry, very friable moist; approximately 30 percent of <br />the horizon is gravel; noncalcazeous, pH 7.4; lower boundazy cleaz <br />and smooth.
