Depth to a Selected Soil Restrictive Layer Rating Bollish Pit <br />value among all components should be remmed. For this aggregation method, percent composition ties cannot occur. <br />The result returned by this aggregation method represents either the minimum or maximum value of the corresponding <br />attribute throughout the map unit. The result may well be based on a map unit component of very minor extent. <br />Component Percent Cutoff: <br />Components whose percent composition is below the cutoff value will not he considered. If no cutoff value is specified, all <br />components in the database will be considered. The data for some contrasting soils of minor extent may not be in the <br />database, and therefore aze not considered. <br />Tie-break Rule: Lower <br />The tie-break rule indicates which value should be selected from a set of multiple candidate values, or which value should be <br />selected in the event of a percent composition tie. <br />Interpret Nulls as Zero: No <br />This option indicates if a null value for a component should be converted to zero before aggregation occurs. This will be done <br />only if a map unit has a[ least one component where this value is not null. <br />,y,~,y g~~,.
