Physical properties, and where possible, chemical properties of each horizon within the sampled <br />profile were described and recorded in the field on standard SCS "232" soil description forms. <br />These properties included: <br />• depth and thickness of horizons <br />• relative position of soil horizons <br />• type and nature of horizon boundaries <br />• color (dry and moist) of horizons <br />• texture (fine earth fraction) <br />• coarse fragment content (type - gravel, cobble, sandstone channer, etc.; size (2mm- <br />3", 3" -10 ", greater than 10 "); and percent ( %) by volume, if significant) <br />• soil structure (type, size, and grade) <br />• soil consistence (dry, moist, and wet) <br />• roots (number, size, and depths) <br />• clay films, if present (number, thickness, occurrence) <br />• effervescence with 0.1 N HCI (none, slight, moderate, strong, violent) <br />• mottles, if present (number, size, distinctness, color) <br />• soil moisture characteristics at the time of sampling <br />In addition, at each soil sampling site, the following parameters were also described: <br />• <br />vegetation <br />• <br />parent material <br />• <br />physiography (geomorphic position) <br />• <br />relief, if significant <br />• <br />elevation (obtainable from topographic maps) <br />• <br />slope <br />• <br />aspect <br />• <br />erosion condition <br />• <br />permeability <br />• <br />internal drainage class <br />• <br />depth to ground water, if encountered <br />• <br />salts or alkali <br />August 2013 (PR 08) 2.04.9 -9 <br />
