Custom Soil Resource Report The sods are rated "good," "fair," or "poor as potential sources of reclamation material The ratings are based on the amount of suitable matenal and on soil properties that affect the ease of excavation and the performance of the matenal after it is in place. The thickness of the suitable material is a major consideration. The ease of excavation is affected by large stones, depth to a water table, and slope. How well the sod performs in place after it has been compacted and drained is determined by its strength (as inferred from the AASHTO classification of the sal) and linear extensibility ( shrink -swell potential). Normal compaction. minor processing, and other standard construction practices are assumed. When the material is property used in reclamation, a rating of "good" means that establishing and maintaining vegetation are relatively easy, that the surface is stable and resists erosion, and that the reclaimed sod has good potential productivity. A rating of "fair means that vegetation can be established and maintained and the soil can be stabilized through modification of one or more properties. For satisfactory performance, it may be necessary to topdress with better suited material or add sod amendments. A rating of "poor" means that revegetation and stabilization are very difficult and costly. To establish and maintain vegetation, it is necessary to topdress with better suited matenal. Numencal ratings between 0.00 and 0.99 are given after the specified features. These numbers indicate the degree to which the features limit the sods as sources of reclamation material. The lower the number. the greater the limitation The map unit components listed for each map unit in the accompanying Summary by Map Unit table in Web Sod Survey or the Aggregation Report in Soil Data Viewer are determined by the aggregation method chosen. An aggregated rating class is shown for each map unit. The components listed for each map unit are only those that have the same rating class as listed for the map unit. The percent composition of each component in a particular map unit is presented to help the user better understand the percentage of each map unit that has the rating presented. Other components with different ratings may be present in each map unit. The ratings for all components, regardless of the map unit aggregated rating, can be viewed by generating the equivalent report from the Soil Reports tab in Web Soil Survey or from the Sal Data Mart site Onsite investigation may be needed to validate these interpretations and to confirm the identity of the soil on a given site. 24
