Custom Soil Resource Report <br />management aspect. Overcoming the unfavorable properties requires special design, <br />extra maintenance, and costly alteration. Unsuited indicates that the expected <br />performance of the soil is unacceptable for the specified management aspect or that <br />extreme measures are needed to overcome the undesirable soil properties. <br />Numerical ratings in the table indicate the severity of individual limitations. The ratings <br />are shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations <br />between the point at which a soil feature has the greatest negative impact on the <br />specified aspect of forestland management (1.00) and the point at which the soil <br />feature is not a limitation (0.00). <br />The paragraphs that follow indicate the soil properties considered in rating the soils. <br />More detailed information about the criteria used in the ratings is available in the <br />"National Forestry Manual," which is available in local offices of the Natural Resources <br />Conservation Service or on the Internet. <br />Ratings in the columns suitability for hand planting and suitability for mechanical <br />planting are based on slope, depth to a restrictive layer, content of sand, plasticity <br />index, rock fragments on or below the surface, depth to a water table, and ponding. <br />The soils are described as well suited, moderately suited, poorly suited, or unsuited <br />to these methods of planting. It is assumed that necessary site preparation is <br />completed before seedlings are planted. <br />Ratings in the column suitability for use of harvesting equipment are based on slope, <br />rock fragments on the surface, plasticity index, content of sand, the Unified <br />classification, depth to a water table, and ponding. The soils are described as well <br />suited, moderately suited, or poorly suited to this use. <br />Reference: <br />United States Department of Agriculture, Natural Resources Conservation Service, <br />National forestry manual. <br />Repo rt-Forestland Planting and Harvesting <br />[The information in this table indicates the dominant soil condition but does not <br />eliminate the need for onsite investigation. The numbers in the value columns range <br />from 0.01 to 1.00. The larger the value, the greater the potential limitation. The table <br />shows only the top five limitations for any given soil. The soil may have additional <br />limitations] <br />25
