Tills sad is in capability subclass Ile and woodland sutaoddy group 2o. 153C—Santiago silt loam, 6 to 15 percent slopes. ihs gently rolling to hilly soil is well drained. It is on crests and sides of hills on ground moraines. Mapped areas are irregular in shape and are commonly 10 to 30 acres. Typically, the surface layer is very dark grayish brown nit 'oam about 6 inches thick. The subsurface layer is brown silt loam about 4 inches thick. The subsoil is about 30 inches thick. The upper part is brown and dark brawn silt loam. The lower part is reddish brown fine sanc'+ 'oam. The underlying material is reddish brown Andy loam, In some places the surface layer has eroded and the silty mantle is less than 15 inches thick. 35 In other places the silty mantle is more than 30 inches thick. Slope is less than 6 percent in some mapped areas. Included with this soil in mapping are small areas of moderately well drained Freeon soils and well drained Kingsley soils. The Kingsley soils formed entirely in sandy loam till, whereas the Santiago soil formed in loess and loamy till. Also included are somewhat poorly drained Freer soils and poorly drained Auburndale soils in small depressions. Permeability of the Santiago soil is moderately slow. Surface runoff is medium to rapid. The available water capacity is high. Natural fertility is medium, and the or- ganic matter content is moderate. Most areas of this soil are farmed. It has good poten- fiat for crops and for grass and legume hay and pasture. It has good potential for woodland. This soil has fair potential for most sanitary facilities and good potential for building site development. This soil is well suited to all crops commonly grown in the survey area. Most areas are used to grow corn and soybeans. The surface layer of this soil is easily eroded and tends to seal during rains and crust on drying. Ero- sion is a severe hazard. In some places contour strip - cropping can be used to control erosion, but most slopes are too short or too irregular for effective contour farm- ing. Minimum tillage can control erosion in most places, or a rotation can be used that includes forage crops. Fail plowing permits clods to be broken by freezing and thawing during the winter, which improves tilth. The use of this soil for pasture and hay is an effective means of controlling erosion. Proper stocking, rotation grazing, and weed control help to keep the pasture and soil in good condition. Planting pasture and hay may be desirable to improve plant species and potential yield. This soil is well suited to trees. Seedling mortality, equipment limitations, and the hazard of erosion are slight. Clearing, spraying, or other site preparation is needed to eliminate brush and reduce plant competition. This soil is well suited to building site development although slope is a limitation. Soil strength is low in the silty mantle but it is high in the underlying material. Be- cause sidehili seepage occurs where slope is more than 12 percent, tile should be installed around foundations to drain off accumulated water. This sail has fair suitability for septic tank absorption fields because of its moderately slow permeability and the hazard of side slope seepage. Lawns, trees, and shrubs are generally easy to establish. This soil is in capability subclass file and woodland suitability group 20. 1558—Chetek sandy loam, 0 to 6 percent slopes. This nearly level to undulating soil is somewhat exces- sively drained. It is on low hills and knolls on broad outwash plains. Delineations are commonly irregular in shape and range from 5 to 20 acres. Typically, the surface layer is dark grayish brown sandy loam about 8 inches thick, and the subsurface
