<br />GREEN RNBR OER7C FINE SANDY LOAM, DEEP OVER GRAVEL, G to 2 percent <br />elapse, Class IIe Land (Gm} <br />This soil occurs along the Gunnison and Colorado Rivera, but for the <br />most part at higher levels than the other Green River soils. Its <br />better poedtion makes it leas susceptible to flooding or ocoasioaal <br />high Water tables. It can be cropped suacesafully, especially after <br />it has been ditched to provide adequate underdrainage. <br />The surface soil, a pale-brown or light browni.ah-gray very fine sandy <br />loam, contains numerous small fragments of mica. Helow depths of <br />10 to 12 inches, the very fine sandy loam hoe a brighter pale-brown <br />or very pale-brown color, and at depths of 24 to 30 inches it grades <br />into s;m;larly textured soil materiel that shows light-gray and reddieh- <br />brown specks or very small spots. Below depths of 3 or 4 feet tex- <br />tural variations are common, but fine sandy loam is dominant. <br />When moist, this soil ie friable. Well~iaeeminated lime is present <br />from the surface downward, but the orgaaia-matter content ie Iow. <br />Workability and filth are exceptionally favorable for irrigation and <br />cultivation, but some places need ditches the.t will'lower the water <br />table. <br />Soil limitations are classified ae severe for local roads and streets <br />(aeaeonal high water tables, poor traffic-supporting capacity, sub- <br />~ect to frost heave), shallow excavations (seasonal high water table), <br />dwellings without basements (seasonal high water table), sanitary land <br />fill (seasonal high water table}, septic tank absorption fields <br />(seasonal high water table), and sewage lagoons (rapid permeability <br />below about 1 foot, seasonal high water tables. ) <br />I <br />
