' 51 - Otero sandy loam, 1 to 3 percent slope <br /> (Information supplied by Soil Conservation Service) <br /> ' This is a deep, well drained soil on gentle plains at elevations of <br /> 4700 to 5250 feet. It formed in mixed outwash and eolian deposits. <br /> Included in this unit are some soils with loam and clay loam underlying <br /> ' material . <br /> Typically the surface layer is brown sandy loam about 12 inches thick. <br /> ' The underlying material , to a depth of 60 inches, is a pale brown calcareous <br /> 1 fine sandy loam. <br /> Permeability is rapid. Available water capacity is moderate. Effective <br /> rooting depth is 60 inches or more. Surface runoff is slow and erosion <br /> hazard is low. <br /> ' This soil is used almost entirely for irrigation and is suited to all <br /> ' t crops adapted to this area. Some conservation practices such as land leveling, <br /> C ditch lining and pipelines may be needed for proper water application. <br /> ' All methods of irrigation are suitable with furrow irrigation the most <br /> common type used. Barnyard manure and commercial fertilizers are needed <br /> ' for top yields along with maintaining good organic matter content. <br /> ' In nonirrigated areas this soil is suited to winter wheat, barley and <br /> .sorghum. Most of the area is planted to winter wheat which is alternated <br /> with summer fallow to allow moisture accumulation. Normally, precipitation <br /> is too low to make beneficial use of fertilizer. <br /> ' Good cultural practices such as stubble mulch farming, strip cropping <br /> ' and minimum tillage are needed to control wind and water erosion. Terracing <br /> may also be needed to control water erosion. <br /> 1 <br /> 1 <br />
