Official Web Soil Survey Available - Soil Science Annual Data Refreshes in October

Madison, Wis. – August 31, 2016 – The National Cooperative Soil Survey Program is an endeavor of the United States Department of Agriculture Natural Resources Conservation Service (NRCS) and other federal agencies; state and local governments; and other cooperators. It provides a systematic study of the soils in a given area, including the classification, mapping, and interpretation of the soils. Soil types are classified from physical properties, drawing heavily on the principles of pedology, geology, and geomorphology.

The entire national official soils data will be refreshed in October during each calendar year to ensure updated official data is available to all farmers, landowners, and partners. Refreshed soil survey information published to the Official Web Soil Survey (WSS) will include the 2012‐2016 Soil Data Join and Recorrelation (SDJR) national initiative, charged by congress to inventory the soils of the U.S., interpret the soils for various uses, publish info to the public, and maintain inventory to meet user needs, will be completed in October. The SDJR national initiative has fully populated components for almost 700 million acres. Almost 2,900 of the 3,300 soil survey areas have been touched during SDJR. Interpretation criteria will be updated for many national interpretations.
