• ~6,~ ._ <br />i <br />48--Honte loam, 0 to 3 percent elopes. This deep, well drained soil <br />Ss on alluvial valley floors, fans and floodplains. Elevation is 7,600 to <br />8,600 feet. This soil formed in calcareous alluvium derived inly from <br />igneous rocks. The average annual precipitation is about 7 in has, and the <br />average annual air temperature is about 41 degrees F. Average frost-free <br />season is about 90 days. <br />Included in this mapping unit are small areas of Luhon loa Carita <br />gravelly loam, and Travelers very stony loam. <br />Typically, the surface layer is light brownish gray loam t at Se <br />calcareous and about 12 inches thick. The underlying material is calcareous <br />grayish brown light clay loam about 8 inches thick that grades to pale brown <br />stratified calcareous Ioam and sandy loam that extends to 60 itches. <br />Permeability is moderate. Effective rooting depth is 60 1 ches or more. <br />Available water capacity is high. Surface runoff is slow and rosion hazard <br />is moderate. Soil blowing hazard is moderate, when plan[ rest ues are <br />removed. <br />This unit is used for range and for irrigated crops of alf lfa, barley, <br />and oats and for irrigated pasture and hayland.`f~ Applications f commercial <br />fertilizers are generally needed in addition to manure and pl t residues. <br />Generally small grains respond to applications of nitrogen fe tilizers and <br />alfalfa and other legumes respond to phosphate fertilizers. 1 <br />tillage practices and high residue crops will help prevent so: <br />Sprinkler irrigation is well suited for all addpted crops <br />The border method of irrigation ie well suited to alfalfa and <br />crops.
