COMPETING SERIES: There are no other series in this family.
GEOGRAPHIC SETTING: Jollymill soils are on ridge tops and side slopes. Slopes are convex and range from 1 to 60 percent. These soils formed in cherty or silty colluvium and the underlying hillslope sediments and residuum from cherty limestone in upper Mississippian geology. Bedrock is dominantly Grand Falls Chert or other hard chert layers, but can be Tripoli, and is dominantly 2 to 6 feet thick. The mean annual temperature varies from 56 to 59 degrees F. The mean annual precipitation varies from 38 to 48 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bendavis, Crackerneck, Hailey, Goss, Noark, and Rueter soils. Bendavis soils are 20 to 40 inches to bedrock. Crackerneck, Hailey, Goss, Noark, and Rueter soils are greater than 60 inches to bedrock. Bendavis soils are on ridge tops and side slopes. Crackerneck soils are on ridge tops and high stream terraces. Hailey soils are on shoulder slopes and side slopes. Clarksville and Noark soils are on ridge tops. Goss and Rueter soils are on side slopes.
DRAINAGE AND PERMEABILITY: Moderately well drained, low to high runoff, moderately slow permeability. The saturated hydraulic conductivity is moderately high. A saturated zone is present at 1.5 to 3.0 feet for a month or more from fall to late spring in most years.
USE AND VEGETATION: These soils are cleared and used for pasture and hayland or remain forested. Native vegetation is mixed hardwoods and pine.
DISTRIBUTION AND EXTENT: The Ozark Highland (MLRA 116A) and Springfield Plain (MLRA 116B) regions of southwest Missouri. This series is of moderate extent, about 52,000 acres have been mapped to date.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Morgantown, West Virginia
SERIES ESTABLISHED: McDonald County, Missouri, 2004. The name is from a civil war era historical site.
REMARKS: These soils were formally included in the Nixa series in southwest Missouri and possibly northwest Arkansas and northeast Oklahoma. They fall on the break between mesic and thermic temperature regimes, and overlap into both.
Diagnostic horizons and features in this pedon include:
1) Ochric epipedon - the zone from 2 to 13 inches (A, and E horizons).
2) Argillic horizon - the zone from a depth of 13 to 51 inches (Bt1, Bt2, 2Bt3, and 3Bt4 horizons).
3) Oxyaquic feature - the zone from a depth of 32 to 57 inches (3Bt4 horizon).
