I � . <br /> PALMS SERIES � <br /> The Palms scries consist of very deep,very poorly drained soils formed in herbaceous organic material l6 i <br /> to 5( inches thick and the underlying loamy deposits in closed depressions on moraines, lake plains, till <br /> plains,outwash plains,and hitlside seep areas,and on backswamps of tlood plains. Permeability is <br /> moderateiy slow to moder�tely rapid in the organic material,and moderate or moderately slow in the loamy <br /> material.Slope ranges from 0 to 6 percent.Mean annual precipitation is Ahout 35 inches,and mean annual <br /> tamperature is about 50 degrees F. <br /> TAXON4MIC CLASS: Loamy, mixed, euic, mesic Terric HapIosaprists ; <br /> TYPICAL PEDON: Palms muck, on 1 percent slope under marsh vegetation at an <br /> elevation of G48 feet. (Colors are for moist soii uniess otherwise stated.) <br /> Oa1--0 to 14 inches; black (lOYR 2/1) broken face and i-ubbed muck(sapric materialj; <br /> ahout S percent fiber, less than 5 percent rubbed; moderate medium granular structure; <br /> slightiy sticky; about 20 to 25 percent mineral material; slightly acid (pH 6.5 in water); <br /> abrupt smooth boundary. <br /> Oa2--14 to 28 inches; black (lOYR 2/1)broken face and rubbed muck(sapric r�aterial); <br /> abaut S percent fiber, less than 5 percent rubbed; massive parting to weak coarse <br /> � subanguiar blocky structure; slightly sticky; 10 to 20 percent mineral material; strongly <br /> acid(pH 5.5 in water); clear smooth boundary. <br /> . Oa3--28 to 35 inches; black (N 2.5/0)rubbed muck(sapric material); about 5 percent <br /> fiber, less than 5 percent rubbed; massive; slightly sticky; 10 to 20 percent mineral <br /> material; moderately acid (pH 6.0 in water}; abrapt smooth boundary.(Combined <br /> - thickness of the Oa horizon�is lb to 51 inches.) <br /> Cg-'-35 to 80 inches; gray (lOYR 5/1) elay loam; massive; friable; common medium <br /> � distinct dark yellowish brown (lOYR 4/4) masses of iron oxide accumulation in the <br /> matrix; neutrai (pH 6.8 in water) in upper part; slightly effervescent, moderately alkaline <br /> in lower part. <br /> ,..

The organic material is derived primarily from herbaceovs plants,but some <br /> layers contain as much as 15 peccent woody materiai. Reaction of the organic material � <br /> ranges from strongly acid to slightly alkaline. Some organic Iayers contain carbonates. <br /> The.surface tier has hue of lOYR to SYR, or is neutral; value of 2, 2.5, or 3, and chroma <br /> � of 0 to 2. It is dominantly sapric material; �owever, some pedons have hemic material. <br /> \ The subsurface and bottom tiers have hue of lOYR to SYR, or are neutrai; value of 2 to 4, <br /> and chroma of 4 to 3. Thin layers, iess than 10 inches thick, of hemic material are in <br />
