Soil are deep to very deep, <br /> moderately coarse to medium textured, moderately well to well-drained, <br /> moderately rapidly to moderately slowly permeable. (Soils in this group <br /> can have slight wetness and slight salinity or alkalinity.) <br /> B Choice of plants limited by DROUTHINESS AND LOA FERTILITY LEVEL. Soils <br /> are coarse to gravelly medium textured, excessively drained, with less <br /> than five inches of available water-holding capacity in the root zone. <br /> C Choice of plants limited by FINE TEXTURES. Soils are deep to very deep, <br /> moderately fine to fine-textured, moderately well-drained, moderately <br /> slowly to slowly permeable. <br /> D Choice of plants limited by VERY SLOWLY PERMEABLE (CLAYPAN) SUBSOILS. <br /> Soils are moderately well-drained, with slow or very slow subsoil <br /> permeability. <br /> E Choice of glants limited by WETNESS. Soils are imperfectly to very poorly <br /> drained. Drained soil phases will be placed in appropriate group <br /> according to their current drainage status. Slight salinity and or <br /> alkalinity may be present.) <br /> F Choice of plants limited by SALINITY OR ALKALINITY. Soils are moderately <br /> to strongly saline alkali, and usually imperfectly to poorly drained. <br /> G Choice of plants limited by DEPTH. Soils are shallow to moderately deep, <br /> well-drained, over hardpan, bedrock or other unfractured dense material. <br /> H Choice of plants limited by LOW pH. Soils are strongly to extremely acid; • <br /> pH is less than 5.1. <br /> I Choice of plants limited by TOXIC PROPERTIES. Soils are usually <br /> moderately to strongly serpentine. <br /> J CHOICE OF PLANTS DEPENDS UPON ON-SITE INVESTIGATION. Soils included those <br /> in the miscellaneous non-arable category, such as river wash, stony or <br /> rocky upland, etc. <br /> 6 <br /> FROM 2099466036 T O 12/1 Vegetative Groups <br /> nF <br />
