<br /> 0 Range of Characteristics: Moderately deep Typic Haplaquolls were described and sampled at site H33. Deep Typic Haplaquolls were described at five
<br /> 00locations across the study area (profile description numbers 8, 21, 36, 37, and 65). Both are poorly drained with the water table typically encountered,
<br /> co at the time of sampling, at about 4 inches. The water table at site 65 was about 30 inches during March, 1988. Gleyed soil conditions exist below this
<br /> depth. The moderately deep Haplaquolls have less than 18 percent clay, whereas the deep Haplaquolls have between 18 and 35 percent clay. Profile depth
<br /> averages 62 inches for the deep Haplaquolls. Reaction is neutral to mildly alkaline and the profile is slightly to strongly calcareous. Coarse fragments
<br /> are typically less than 15 percent. The site specific Haplaquoll soils are similar to Aquolls as described by SCS in the completed but unpublished San
<br /> Migel Area Soil Survey. Associated vegetation at the sample sites consists of sedges, willows, grasses, and cattails.
