46 - Busby loam, to 2 percent slopes. This deep, well 

 drained soil is on stream terraces. It formed in alluvium. 

 Slope is to 2 percent. 



The surface layer of this soil is a loam about 5 inches 

 thick. The subsoil is a loam about 1 1 inches thick- The 

 substratum to a depth of 48 inches or more is mainly a fine 

 sandy loam. 



Permeability is moderately rapid and available water 

 capacity is about 6 inches in the upper 48 inches. 



This soil is well suited to irrigated crops. This map unit 

 is Class 1 irrigated. 



47 - Busby- Rock outcrop complex, 8 to 1 5 percent slopes. 



This map unit is on uplands. Slope is 8 to 1 5 percent. 



This unit is about 50 percent Busby fine sandy loam and 

 50 percent sandstone Rock outcrop. The Busby soil is on 

 short fans, and the Rock outcrop is on knobs and ridges. The 

 Busby soil formed in alluvium. 



The Busby soil is deep. 



This map unit is not suited to irrigated crops because of 

 the areas of Rock outcrop. This map unit is class 6. 



56 - Cambeth silt loam, 2 to 8 percent slopes. This mod- 

 erately deep, well drained soil is on uplands. Slope is 2 to 8 

 percent. 



The surface layer of this soil is a silt loam about 5 inches 

 thickThe underlying soil material is a silt loam. Below this, 

 toa depth of48 inches or more, are loamy sedimentary beds. 



Permeability is moderate, and available water capacity 

 is about 5 inches. The effective rooting depth is limited by 

 the sedimentary beds at a depth of 20 to 40 inches. 



This soi 1 is poorly sui ted to irrigated crops because of the 

 moderate depth to the sedimentary beds. This map unit is 

 class 6 irrigated. 



57 - Cambeth silt loam, 8 to 15 perrent slopes. This 

 moderately deep, well drained soil is on uplands. Slope is 8 

 to 1 5 percent. 



The surface layer of this soil is a silt loam about 4 inches 

 thick. The underlying soi 1 material is a silt loam. Below this, 

 to a depth of 48 inches or more, are loamy sedi men tary beds. 



Permeability is moderate, and available water capacity 

 is about 5 inches. The effective rooting depth is limited by 

 the sedimentary beds at a depth of 20 to 40 inches. 



This map unit is poorly suited to irrigated crops because 

 of the moderate depth to sedimentary beds. This map unit 

 is class 6 irrigated. 



58 - Cambeth-Cabbart silt loams, 4 to 1 5 percent slopes. 

 This map unit is on uplands. Slope is 4 to 15 percent. 



Thisunitisabout65 percent Cambeth silt loam and 35 

 percent Cabbart silt loam. These soils formed in residuum 

 from loamy sedimentary beds. 



The Cambeth soil is moderately deep and well drained. 

 The surface layer is a silt loam about 5 inches thick The 

 underlying soil material is a silty clay loam. Below this, to a 

 depth of 48 inches or more, are loamy sedimentary beds. 

 Permeability is moderate and available water capacity is 

 about 5 inches. The effective rooting depth is limited by the 

 sedimentary beds at a depth of 20 to 40 inches. 



The Cabbart soil is shallow and well drained. The soil 

 material is a silt loam. Below this, to a depth of 48 inches or 

 more, are loamy sedimentary beds. Perm eabilit}' is moderate 

 and available water capacity is about 2 inches. The effective 

 rooting depth is limited by the sedimentary beds at a depth 

 of 10 to 20 inches. 



This map unit is pooriy suited to irrigated crops because 

 of the shallow to moderate depth to sedimentary beds. This 

 map unit is class 6 irrigated. 



6 1 - Castner-Shambo complex, 2 tol 5 percent slopes. This 

 map unit is on uplands. Slope is 2 to 1 5 percent. 



This unit is about 50 percent Castner channery loam 

 and 50 percent Shambo loam. The Casmer soil formed in 

 residuum derived from sandstone. The Shambo soil formed 

 in alluvium derived from loamy sedimentary beds. 



The Castner soil is shallow and well drained. The soil 

 material is a channery or very channery loam. Below this, to
