Soil survey interpretation comprises the organization and presentation of knowledge about characteristics, qualities, and behavior of soils as they are classified and outlined on maps. This knowledge should be organized and presented in ways that will help people to make more intelligent decisions in their uses of soils. Agricultural users should be helped to make proper choices from available alternatives in use and management of soils for plant production. Engineering users should be helped to make choices among possible designs for subgrades, types of foundations, and the like. Hydrologists should be able to estimate runoff and water yields more accurately. Soil survey interpretations should help these and other users to make full and effective application of the knowledge available about soils.

Soil surveys are a tool for improving the assessment of rural lands. The soil classification provides the means for utilizing factual information in making the necessary physical predictions of soil productivity. With these predictions economic ratings for different uses of each soil can be made. The soil map showing the location and extent of each soil permits the application of these economic ratings to specific tracts of land resulting in the first approximation of the assessed value. These must be adjusted for roads, schools, and other factors affecting the value.
