I I I I I I I I I I I I I I I I I I I Appendix II: Soil Descriptions Adapted from the Anoka County Soil Survey USDA SCS, 1977 Alluvial Land This land is nearly level and poorly drained and frequently flooded. It formed in mixed alluvial material that varies in texture and color. It is common along streams and rivers. The texture at the surface can be sandy, loamy, or mucky peat. The underlying material varies from sands, loams, and organic soil material. The permeability of this material varies and the available water is moderate to high. Natural fertility is moderate. Flooding is common in the spring with floodwater commonly at depths from one to four feet. This land is poorly suited for most uses because of the hazard of flooding and poor drainage. Anoka Series The Anoka series has nearly level to sloping, somewhat excessively drained soils formed in outwash sands on broad outwash plains. A typical profile consists of a dark grayish-brown loamy fine sand that is about eight inches thick. Below the surface horizon is dark brown and brown loose loamy fine sand and fine sand. The permeability is moderately rapid and the available water capacity is moderate. The organic matter content is low. The supply of available nitrogen and potassium are low and phosphorus is medium. Limitations occur because of the moderate available water capacity and the resulting hazards of drought and soil blowing. Braham Series The Braham series has undulating to hilly, somewhat excessively drained soils formed in a sandy mantle and the underlying loamy till. These soils are on the upland ground moraines. The representative profile has a surface layer is very dark grayish-brown loamy fine sand. Below a depth of about eighteen inches, there is a yellowish-brown sandy clay loam. The permeability is rapid in the upper eighteen inches of the soil and moderate in the lower part. The available water capacity is moderate. The organic matter content is low. The supply of nitrogen and potassium is low and phosphorus is medium. The main uses for Braham soils are for agriculture and urban development. The limitations of this soil are moderate available water capacity and the accompanying hazards of erosion and drought. Brickton Series This series consists of nearly level, poorly drained soils formed in glacial. lake sediment. They are usually in depressional areas. 35
