Finding Soil Surveys at Renne Library
Where can I find soil surveys?
Soil Surveys can be found in the Library Catalog. Patrons can locate the soil surveys in the Catalog by doing a Subject search for "soil surveys [state name]" or "soil surveys [state name] [county name]". For example, to search for Gallatin County soil surveys, type in "soil surveys montana gallatin". To find all of the Montana soil surveys the library owns, search for "soil surveys montana".
Soil Surveys at Renne Library are located in the Government Documents section, which is in the Basement. The call number is A57.38. Browsing the surveys can be difficult; they are arranged differently depending on when they were published. To find your soil survey:
- 1899-1963: Soil surveys are arranged by year and then by series number (assigned by Soil Conservation Service).
- 1964-1993: Soil surveys are arranged by county name and then by state name. For example, the 1987 soil survey for Adams County, North Dakota, can be found at A 57.38:Ad 1/12, indicating that this is the first of 12 Adams Counties.
- 1994-2006: Soil surveys are arranged by state name and then by county name. For example, the 1996 soil survey for Taney County, Missouri, can be found at A57.38/25:T 15. Missouri is the 25th state alphabetically, and T15 indicates the county name.
- 2007-present: The most recent soil surveys are only available online from the USDA.
How is soil survey information organized?
Each soil survey is organized in two parts:
1.) County information, including history, topography, resources, and a detailed description of soils.
2.) County soil maps organized by order, suborder, great group, subgroup, family, and series. Classifications are based on field and laboratory observations.
Where can I find additional soil surveys?
The USDA has many current soil surveys available online. For these and other resources, check out the other tabs in the Guide.
Did You Know?
Montana has an official state soil -- Scobey soil.
The Scobey series consists of very deep, well drained soils on till plains,hills, and moraines in the north-central part of Montana. These soils occur on more than 700,000 acres. They are among the most productive soils in Montana's Golden Triangle, an area known for its ideal climatic conditions for growing wheat of exceptionally high quality. The three points of the Golden Triangle are Havre, Conrad, and Great Falls. The main crops grown on Scobey soils are spring and winter varities of nonirrigated wheat.
These soils formed in glacial till and under prairie vegetation. The average annual precipitation is about 12 inches. The average annual temperature is about 43 degrees F. The frost-free period is about 115 days.
These soils are named for the town of Scobey, in northeast Montana. The series was established in 1928.
