The bottom layer could be set at 152 cm or 200 cm. \n

The root depth refers to the soil depth that can be exploited based on restrictions other than physical ones (lithic, paralithic, duripans and petrocalcics). \nRecognition of root limiting layers involves at least 3 chemical barriers to root growth. The first kind is a layer having a pH of less than 3.5. The second\none is a layer having an electrical conductivity of more than 12. The third kind is a possible dense layer determined through an examination of the differential \nbetween the populated bulk density of a layer and a theoretical optimum density. If the differential reaches a threshold, then the layer is considered to stop \nroot growth. If no root-restricting zone is identified, a depth of 152 cm is used to approximate the maximum rooting depth.<\/p>\n

Values for each component (soil type) were selected only where the data were not missing and \nthe component kind was not \u2018Miscellaneous area\u2019. Miscellaneous areas were excluded since they are dominantly occupied by\nnon-soil materials. Major miscellaneous areas include badlands, beaches, chutes, cinder lands, dams, dumps, dune lands, glaciers, gullied land,\nlava flows, mined lands, oil-waste land, pits, playas, riverwash, rock outcrop, rubble land, slickens, urban land and water. \nDetailed descriptions of each category can be found in the National Soil Survey Handbook, Part 627 - Legend Development and Data Collection, \nSubpart B - 627.10 (U.S. Department of Agriculture, Natural Resources Conservation Service.

Miscellaneous areas (non-soil\nmaterials) did not contribute to the map unit weighted average so the weighted mean represents only the\nsoils in each map unit. The remaining soil components were scaled to represent 100% of the map unit\nand weighted accordingly in the calculation of the map unit average. Values for map units dominated by non-soil material, or with more than 50% \nas \u2018Miscellaneous area\u2019 were set to null.<\/p>\n\n
