Soil Survey Of Josephine County, Oregon1

The Soil Survey contains information that can be used for soil resource management decisions such as land use requests/applications to the Josephine County Planning Department.  The Soil Survey contains information on chemical and physical soil characteristics that will help predict soil behavior for selected land uses.  The survey also highlights limitations inherent in the various soil types and discusses improvements needed to overcome the limitations.

This soil survey is designed for many different users. Farmers, ranchers, foresters, planners, community officials, engineers, developers, builders and home buyers are just a few of the more common users of soil survey information. Many land use decisions such as building site selection, food and fiber production, wildlife management, recreational development, waste disposal, zoning decisions and pollution control are based on soil conditions.

Great differences in soil properties such as drainage, flooding, depth to bedrock, shrink and swell potential, soil texture, permeability and rock fragment content can occur within short distances. These and many other soil properties that affect land use are described in this soil survey. The location of each soil is shown on the detailed soil maps. Each soil is described and interpretations for specific uses are given.

Value Of Survey

The Soil Survey has 157,532 acres (15%) of 2nd order survey, 880556 acres (85%) of 3rd order survey, and 1,912 acres (0%) of water.2

This survey was mapped at two levels of intensity or detail. The more detailed part of the survey would be considered a 2nd order level and the less detailed part would be a 3rd order level. Soil map units in the 2nd order level are identified by field observation and by remotely sensed data. This data is considered intensive and is to be used for general agriculture and urban planning.

One of the most important parts of the soil survey is the map unit description. These descriptions not only tell what the soil is and give a full description but also name other soils that are typically found within the boundaries of the map unit. One very important aspect to keep in mind is that up to 20 percent of a mapping unit can be occupied by contrasting soil types. These contrasting soil types are called “inclusions” and usually have different management characteristics.
