weldrge <br />Map ~ Soil name and description <br />Symbol <br />This unit is suited for irrigated hay and pasture. <br />Furrow, drip, and sprinkler irrigation is suited to <br />this soil. Irrigation water needs to be applied et a <br />rate that insures optimum production without increasing <br />deep percolation, runoff, and erosion. Use of pipe <br />reduces water toss aM deep percolation. Tilth and <br />fertility can be improved by returning crop residue to <br />the soil and using a suitable rotation. Excessive <br />cultivation can result in the formation of a tillage <br />pan. This pan can be broken by subsoiling when the <br />soil is dry. Because of the undulet ing topography and <br />slope, onsite investigations are needed before <br />leveling. Care should betaken in leveling designs to <br />avoid cuts into unsuitable soil material. <br />This unit consists of very deep, well drained soils on <br />alluvial fans and terraces. These soils formed in <br />mixed alluvium derived from sedimentary rock sources. <br />The surface layer is loam about 18 inches thick. the <br />upper 29 inches of the underlying materiel are clay <br />loam with strata of loamy send, ge low this to a depth <br />of more than 60 inches is sandy loam and sandy clay <br />loam. Permeability of this soil is moderately slow. <br />Available water capacity is high. Effective rooting <br />depth is 60 inches or more. Runoff is medium, and the <br />hazard of water erosion is moderate. Piping is a <br />hazard. <br />This unit is considered prime farmland. <br />Capability Subclass 3E; irrigated; 7C; nonirrigeted <br />Capability classification is the grouping of soils to <br />show, in a general way, their suitability for oast <br />kinds of farming. It is a practical classification <br />based on limitations of the soils, the risk of damage <br />when they ere used, and the way they respond to <br />treatment. the soils are classified according to <br />degree erd kind of permanent limitation, but without <br />consideration of major and generally expensive <br />landforming that would change the slope, depth, or <br />other characteristics of the soils; without <br />consideration of possible unlikely major reclamation <br />projects. <br />
