CM layer is brown loam about 6 inches thick. The subsoil is about 8 inches thick. The upper part is dark reddish brown gravelly sandy loam, and the lower part is brown gravelly coarse sand. The underlying material is brown and light brown gravelly sand and gravelly coarse sand. In some places the underlying material contains less than 15 percent coarse fragments. In places the sandy loam mantle is thicker than 20 inches. In other areas the slope is more than 6 percent. Included with this soil in mapping are small areas of Kingsley and Poskin soils. The Kingsley soils are well drained and formed entirely in loamy glacial till, whereas the Chetek soil formed in a loamy mantle and sandy outwash. The Poskin soils are somewhat poorly drained and have a thick silty surface mantle underlain by gravel- ly sand. They occupy depressions. The Chetek soil has moderately rapid permeability in the sandy loam mantle and rapid permeability in the gravelly sand underlying material. Surface runoff is slow. Natural fertility, available water capacity, and organic matter content are low. Most areas of this soil are woodland or cropland. It has fair to poor potential for cultivated crops, pasture, and hay, It has fair potential for woodland. This soil has poor potential for most sanitary facilities and good poten- tial as building sites. The Chetek soil has fair to poor suitability for crops. The main limitations are low available water capacity and the hazard of erosion. Minimum tillage, crop rotations that include forage crops, and returning crop residues to the soil reduce erosion and improve available water ca- pacity and fertility. This soil is well suited to irrigation. The production of hay crops is limited by low available water capacity. Conservation practices for hayland in- clude planting approved and adapted species, fertilizing, and timely harvesting. When the soil is pastured, proper stocking, rotation grazing, and weed control help to maintain an adequate vegetative cover. Supplemental pasture is usually needed during the dry summer months. This soil has fair suitability for trees. Tree seedlings survive and grow well if competing vegetation is con- trolled. Site preparation, spraying, or clearing are desir- able methods of controlling competing vegetation. This soil is well suited to building site development and is poorly suited to most sanitary facilities. Sidewalls of the underlying sand and gravel have poor stability and may cave in during excavation. This can be prevented with temporary retaining walls. Septic tank absorption fields function well in this soil. Because of the rapidly permeable underlying material, however, they must be specially designed to prevent the pollution of ground water supplies. Revegetating the landscape may be difficult, and additions of water and fertilizer are needed to keep lawns, trees, and shrubs growing vigorously. A loamy topdressing may be desir- able before establishing lawns. This soil is generally a good source of sand for construction. Consideration should be given to this resource before soil for other uses.
