Soils <br />The soils of this site are deep, somewhat poorly drained and <br />occur on terraces and bottomlands. The soils formed in <br />calcareous alluvium. The soil texture ranges from sandy loam to <br />clay. <br />Permeability is slow to moderate with a high to moderate <br />available water capacity. Surface runoff is slow to moderate. <br />Effective rooting depth of these soils is 60 inches more. <br />Soil Surface Slope <br />Series Texture Range Phase <br />Alda <br />Alda loam <br />fi 0-3 saline <br /> <br />Apishapa ne sandy loam <br />clay 0-3 <br />0 saline <br /> <br />Haverson <br />loam -3 <br />0-3 - <br />saline <br />Hayford silty clay loam 0-3 saline <br />Heldt clay loam 0-3 saline
