<br />Soil complexes were only used where two or more soil <br />and/or land types were ,so intermixed that delineation was <br />impractical or unneccessary for the intended use of the <br />survey. These complexes generally contain soil types with <br />similar topsoil availability and suitability with similar <br />depths, slopes, and physical and chemical characteristics. <br />Associations are generally used in areas which will <br />not be disturbed or where field observations conclusively <br />determined that the associated series were unsuitable because <br />of stoniness, cobbly texture, or related problems. They were <br />not applicable to this project. <br />• 1.4.4 Sampling and Profile Description <br />Representative profiles from three soil series phases <br />or phase of series variants were sampled and described in <br />detail. The representative profile for the sample soils was <br />selected on the basis of median characteristics for parent <br />material, landscape position, physical characteristics, and <br />vegetation. Each profile was sampled and described by horizon <br />to a depth of more than 60 inches or bedrock. Surface and <br />subsoil horizons were sampled at intervals of one foot~'or ~~ <br />less. Subhorizor.- were sampled at intervals of 18 inches <br />or less to a depth of six feet or bedrock. <br />A one-quart sample from each soil horizon, subdivided <br />~. horizon or contrasting layer was collected and air-dried. <br />-7- <br />
