ll4 Loamy Plains MLRA 49 6 70 associated with Percent Slope? Baca silt loam Capulin loam Torreon silt loam MAJOR USES AND INTERPRETATIONS FOR: This site provides excellent forage for cattle and horses at any time during the year but is especially good during the growing season. It also provides good forage for sheep and antelope and small mammals. The animal forage preference changes as the growing season progresses. Western wheatgrass is very nutritious during the early spring. It is important that planned deferment and rotation be scheduled so western wheatgrass is not grazed out and replaced by less desirable plants. Other grasses that need spring deferment are the needle grasses, Indian ricegrass and bottlebrush squirreltail. The warm season grasses such as blue grama and sideoats grama will be benefitted by deferment from grazing during the late spring and early summer months and maintain their nutritious value well after maturing and therefore make excellent winter forage. Vegetative palatability will influence proper use considerations. The season of use, kind of grazing animal, past grazing use and the plant composition will directly influence the animal preference and performance. This site has a fair potential for wildlife habitat. It supports a good population of antelope and jackrabbit. Watershed (Hydrologic Interpretation) Soils in this site are grouped into "B" and "C" hydrologic groups, as outlined in the "Soils of Colorado Loss Factors and Erodibility Hydrologic Groupings 1979" handbook. Field investigations are needed to determine hydrological cover conditions and hydrologic curve numbers. The hydrologic curve number for_ group B soils are about 61 and group Cis about 74, when the hydrologic conditions a good, as shown in "Peak Flows in Colorado" handbook. Refer to SCS National Engineering Handbook, Section 4, to determine runoff quantities from the curves. 2 Slope ranges are based on Colorado soil mapping units.
