<br />NONTECHNICAL SOUS DESCRIPTION REPORT <br />weldrge <br />Map ~ Soil name atd description <br />gymbol <br />Av ~ Avalon sandy loam, 2 to 5 percent slopes <br />This unit is suited for irrigated hay and pasture. <br />Furror, drip, and sprinkler irrigation is suited to <br />this soil. Irrigation rater needs to be applied at a <br />rate that insures optimum production without increasing <br />deep percolation, runoff, and erosion. Use of pipe <br />reduces water loss end deep percolation. Tilth and <br />fertility can be improved by returning crop residue to <br />the snit 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 undulating topography and <br />slope, onsi to 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 />intermediate valley terraces. These soils formed in <br />loess modified alluvium derived dominantly from mixed <br />shale and sandstone sources. The surface layer is <br />satdy loam about 3 inches thick. The upper 74 inches <br />of the subsoil are loam, and the loner 13 inches are <br />clay loam. The upper 12 inches of the substratum are <br />clay loam, end the loner part to a depth of more than <br />60 inches is gravelly loam. Permeability of this soil <br />is moderate. Available rater capacity is high. <br />Effective rooting depth is 60 inches or more. Runoff <br />is slow, and the hazard of water erosion is slight. <br />This unit is considered prime farmland. <br />Capability gubc lass 3E; irrigated; 7C; nonirrigated <br />
