The Soils of Elgin County - Agriculture and Agri-Food Canada

Procedure :1) Locate the symbols 'BV" and "TA" in the firstcolumn of Table 4 titled 'Map Symbol".2) Determine the appropriate slope class columnsby locating slope class 'b" and slope class "c"which appear under the heading titled"Capability classification by slope classes".3) The soil capability ratings for the soilsidentified in the symbol are shown where thehorizontal lines and vertical columns intersect.Therefore, the capability rating for BV soilswhich occur on b slopes is 2D, and thecapability rating for TA soils which occur on cslopes is 2T .4) The soil capability rating for the map symbolis 2D>2T.Example 5.AL, ER, SC, or VCThese symbols represent miscellaneous landunits. In Table 4, a capability rating is given foreach of these units which is the range of soilcapabilities that generally occur in all areas wherethese land units were identified. The capabilitiesof the soils within individual areas mapped asthese land units, therefore, may vary . Forexample, two areas may be identified on one ofthe soil maps. as Alluvium (AL), and both arerated Class 31 to 51 in Table 4 . One of the areas,however, may be composed entirely of soils whichhave a capability of Class 31. The other area maybe composed entirely of soils which have acapability of Class 51.
