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

Procedure:1) Locate the symbols 'BV" and 'TO" in the firstcolumn .of Table 6 tided 'Map Symbol" .2) Determine the suitability rating for BV soils bymoving horizontally across the line for BVsoils and locating slope class "b" in the columntitled "Slope classes /Management factors" .On that line, move horizontally to Crop Groupcolumn #4 (Cucumbers), where the suitabilityrating of Class S3 is given. Now move downthe column to see if the rating should beupgraded because of management factors .Since there is a +1 beside 'Drainage", therating would be Class S2 if the BV soils are tiledrained .3) Now determine the suitability rating for TOsoils by moving horizontally across the line forTO soils and locating slope class 'b" in thecolumn titled "Slope classes/Managementfactors". On that line, move horizontally toCrop Group column #4 (Cucumbers), wherethe suitability rating of Class S4 is given . Nowmove down the column to see if the ratingshould be upgraded because of managementfactors. Since there is a +2 beside 'Drainage',the rating would be Class S2 if the TO soilsare tile drained .4) The soil suitability rating for the map symbolfor cucumbers is Class S3>S4 if the soils arenot tile drained. If the soils are the drained,the rating is Class S2 since both soils have thesame rating.upgraded because of management factors .Since there is a +1 beside 'Drainage", therating would be Class S2 if the BV soils are tiledrained .3) Now determine the suitability rating for TAsoils by moving horizontally across the line forTA soils and locating slope class "c" in thecolumn titled "Slope classes/Managementfactors" . On that line, move horizontally toCrop Group column #4 (Cucumbers), wherethe suitability rating of Class S2 is given. Nowmove down the column to see if the ratingshould be upgraded because of managementfactors. Since there is a +1 beside 'Drainage,the rating would be Class Sl if theTA soils aretile drained.4) The soil suitability rating for the map symbolfor cucumbers is Class S3>S2 if the soils arenot tile drained . If the soils are the drained,the rating is Class S2>Si .Example 4.BV>TAb>cIn this example, 40 to 80% of the area representedby the symbol consists of Beverly (BV) soils whichare the dominant soils . They occur on complex bslopes of 0.5 to 2% . In addition, 20% to less than40% of the area consists of Tavistock (TA) soilswhich are the significant soils. They occur oncomplex c slopes of 2 to 5%.Procedure:1) Locate the symbols 'BV" and 'TA" in the firstcolumn of Table 6 titled 'Map Symbol" .2) Determine the suitability rating for BV soils bymoving horizontally across the line for BVsoils and locating slope class "b" in the columntitled "Slope classes/Management factors".
