{ "culture": "en-US", "name": "", "guid": "", "catalogPath": "", "snippet": "", "description": "\"Drainage class (natural)\" refers to the frequency and duration of wet periods under conditions similar to those\nunder which the soil formed. Alterations of the water regime by human activities, either through drainage or\nirrigation, are not a consideration unless they have significantly changed the morphology of the soil. Seven\nclasses of natural soil drainage are recognized-excessively drained, somewhat excessively drained, well drained,\nmoderately well drained, somewhat poorly drained, poorly drained, and very poorly drained. These classes are\ndefined in the Soil Survey of Multnomah County, Oregon; 1983.\n\nSource: 2007 NRCS.
