• • • Rifle Soil Series Official Soil Series Description The Rifle series consists of very deep, very poorly drained soils formed in organic deposits more than 51 inches thick in bogs and depressional areas within ground moraines, end moraines, outwash plains, and lake plains. These soils have moderately rapid permeability. Slopes range from 0 to 2 percent. Mean annual precipitation is about 30 inches and the mean annual temperature is about 42 degrees F. TAXONOMIC CLASS: Euic, frigid Typic Haplohemists TYPICAL PEDON: Rifle mucky peat - undisturbed. (Colors are for moist soils.) Oil - -0 to 2 inches; yellowish brown (10YR 5/4) broken face and rubbed peat, light yellowish brown (10YR 6/4) pressed; 90 to 100 percent sphagnum moss rubbed; massive; neutral; clear smooth boundary. 0i2- -2 to 4 inches black (5YR 2/1) broken face, rubbed and pressed peat; about 90 percent fiber, 60 percent rubbed; massive; primarily sphagnum moss and some woody fragments; neutral; abrupt smooth boundary. Oel - -4 to 8 inches; black (5YR 2/1) broken face and rubbed mucky peat, dark reddish brown (5YR 2/2) pressed; about 30 percent fiber and 10 percent rubbed; weak fine granular structure; woody and herbaceous fibers; neutral; abrupt smooth boundary. 0e2 - -8 to 20 inches; dark reddish brown (5YR 2/2) broken face, rubbed and pressed mucky peat; about 65 percent fiber and 20 percent rubbed; weak thick platy structure; primarily herbaceous fibers few woody fragments; neutral; clear smooth boundary. 0e3 - -20 to 39 inches; dark reddish brown (5YR 2/2) broken face and rubbed mucky peat, dark reddish brown (5YR 3/3) pressed; about 80 percent fiber and 20 percent rubbed; weak thick platy structure; primarily herbaceous fibers; neutral; gradual smooth boundary. 0e4 - -39 to 60 inches; dark reddish brown (5YR 2/2) broken face, rubbed and pressed mucky peat; about 70 percent fiber, and 15 percent rubbed; weak thick platy structure; primarily herbaceous fibers; neutral. TYPICAL LOCATION: Delta County, Michigan; about 4 miles northeast of the town of Bark River 1700 feet south and 350 feet west of the northeast corner, sec. 13, T. 39 N., R. 24 W. RANGE OF CHARACTERISTICS: The thickness of the organic soil layers exceeds 51 inches. The organic material is estimated to be primarily herbaceous fibers, however, some pedons contain less than 15 percent by volume of woody fragments that cannot be crushed between the fingers. The layers in the subsurface tier typically have pH of 4.5 to 6.5 in O.O1M CaC12, but range from pH 5.6 to 7.3. The organic soil materials lack free carbonates in all parts of the control section. Some pedons contain surface layers composed of hemic or sapric material. The layers in the surface tier are quite variable in color depending upon the stage of decomposition. Hue ranges from 10YR to 5YR, value from 2 to 6, and chroma from 1 to 4. The fibers in these layers are primarily coarse granular or weak thick platy structure or the layers in the subsurface and bottom tier have hue of 10YR, 7.5YR or The Preserve Conservation Development - Restoration and Management Plan B -10
