SOIL SURVEY OF BARTON COUNTY MISSOURI

3. Barco-Collinsville association
Shallow to moderately deep, well-drained^ gently sloping to moderately steep soils of the uplands; formed under grass in sandstone residuum

This association borders most of the larger streams and many upland drainageways in the county, except Dry Wood Creek and its tributaries. The landscape is characterized by somewhat broken, gently sloping, rounded divides that have gently sloping to moderately steep sides and are adjacent to flood plains (fig. 4). The broad and narrow bottoms of the North Fork of the Spring Eiver and its tributaries are examples of the kind and extent of bottom lands included in this association. Barco and Collinsville soils are well drained, and both formed mainly in sandstone residuum. The association occupies about 26 percent of the county.
Barco soils make up about 56 percent of the association; Collinsville soils, 19 percent; Hepler, Radley, Verdigris, and Cleora soils, 15 percent; and Parsons and Barden soils, the remaining 10 percent. Figure 4.-The major soils in the Barco-Collinsville and the Hector-Bolivar associations, showing their
general location on the landscape and the material in which they formed.

    Barco soils are gently sloping, and in places the slopes are broken. These soils occupy rounded divides, side slopes, and foot slopes. The surface layer of Barco soils is very dark brown loam about 11 inches thick. The subsoil grades from dark-brownish, friable loam to mottled, brownish sandy clay loam. Depth to bedded sandstone is 20 to 40 inches.
    Collinsville soils are gently sloping to moderately steep, and in many places the slopes are broken. Narrow ridgetops and points, side slopes, breaks, and knobs are all common landscape features. About one-fourth of the acreage of these soils is stony. Bedrock outcrops are common in some areas of both the nonstony and the stony Collinsville soils. The surface layer is dark-brown fine sandy loam about 10 inches thick. A thin, dark yellowish-brown subsoil is present in some places. Depth to bedded sandstone is less than 20 inches.
    Hepler, Radley, Verdigris, and Cleora soils are on bottom lands. The moderately well drained Radley and Verdigris soils and the well drained Cleora soils occupy narrow, low positions near stream channels. The somewhat poorly drained Hepler soils occupy the higher and wider flood plains.
    Parsons and Barden soils are on uplands. These deep, nearly level or gently sloping soils occupy divides and benches.
    About 65 percent of this association is used for pasture or hay. Stony areas of Collinsville soils are idle or are used for pasture. Wheat, grain sorghums, grasses, and legumes arc grown on a large part of the acreage. Corn and soybeans also are grown. General livestock and grain farming are the main enterprises in this association.
    Soils of the uplands and bottom lands are mostly low or medium in fertility. The bottom lands are subject to occasional or frequent overflow. Droughtiness and erosion in the uplands and wetness on the bottom lands are major limitations to the use of this association
