Soil Information for All Uses <br /> Soil Reports <br /> The Soil Reports section includes various formatted tabular and narrative reports <br /> (tables) containing data for each selected soil map unit and each component of <br /> each unit. No aggregation of data has occurred as is done in reports in the Soil <br /> Properties and Qualities and Suitabilities and Limitations sections. <br /> The reports contain soil interpretive information as well as basic soil properties and <br /> qualities. A description of each report (table) is included. <br /> Land Classifications <br /> This folder contains a collection of tabular reports that present a variety of soil <br /> groupings. The reports (tables) include all selected map units and components for <br /> each map unit. Land classifications are specified land use and management <br /> groupings that are assigned to soil areas because combinations of soil have similar <br /> behavior for specified practices. Most are based on soil properties and other factors <br /> that directly influence the specific use of the soil. Example classifications include <br /> ecological site classification, farmland classification, irrigated and nonirrigated land <br /> capability classification, and hydric rating. <br /> Land Capability Classification <br /> The land capability classification of map units in the survey area is shown in this <br /> table. This classification shows, in a general way, the suitability of soils for most <br /> kinds of field crops (United States Department of Agriculture, Soil Conservation <br /> Service, 1961). Crops that require special management are excluded. The soils are <br /> grouped according to their limitations for field crops, the risk of damage if they are <br /> used for crops, and the way they respond to management. The criteria used in <br /> grouping the soils do not include major and generally expensive landforming that <br /> would change slope, depth, or other characteristics of the soils, nor do they include <br /> possible but unlikely major reclamation projects. Capability classification is not a <br /> substitute for interpretations designed to show suitability and limitations of groups of <br /> soils for rangeland, for forestland, or for engineering purposes. <br /> In the capability system, soils are generally grouped at three levels: capability class, <br /> subclass, and unit. <br /> 18 <br />
