Soil Survey Geographic Database (SSURGO)
Definition
The Soil Survey Geographic Database (SSURGO) is a comprehensive digital database that provides detailed soil information, primarily for the contiguous United States. It is developed by compiling information from field and laboratory data of the National Cooperative Soil Survey and is intended for use by land managers, agricultural professionals, city planners, and researchers who require extensive soil data for various applications. SSURGO encompasses a range of soil parameters including soil taxonomy, physical and chemical soil properties, interpretations for specific uses, and more.
What is Soil Survey Geographic Database (SSURGO)?
The Soil Survey Geographic Database (SSURGO) is a crucial tool for comprehending diverse soil characteristics across the United States. Soil conductivity, a parameter within SSURGO, is a measure of how easily an electric current can pass through soil. It is influenced by factors such as moisture content, soil texture, and the concentration of ions present. Conductivity data can be integral for applications in agriculture to assess soil salinity, guide irrigation practices, and identify areas at risk for soil degradation. By using the SSURGO, stakeholders can access high-resolution spatial data and detailed tables that provide crucial insights into soil performance and suitabilities essential for effective land use management.
FAQs
What types of data are included in the SSURGO?
SSURGO contains extensive data, including soil maps, soil characterization data, and soil interpretations. The database offers a wealth of information on soil taxonomy, physical and chemical properties, and interpretations related to land use suitability such as agriculture, engineering, and ecology.
How can conductivity information from SSURGO be applied in agricultural practices?
Conductivity information from SSURGO can help farmers identify saline soils, which can impact crop yield. By understanding conductivity levels, farmers can implement appropriate soil management and irrigation strategies to mitigate salinity and improve water use efficiency.
Who can benefit from using SSURGO data?
SSURGO data is valuable for a diverse group of users, including land managers, agricultural professionals, urban planners, engineers, environmental scientists, and researchers who need detailed information about soil characteristics for decision making and planning.
How frequently is SSURGO data updated?
SSURGO data is updated periodically to reflect the latest soil surveys conducted by the National Cooperative Soil Survey. However, the update frequency can vary depending on the region and the availability of new soil survey data.
What tools are available to access and visualize SSURGO data?
Various GIS software platforms and online mapping tools are available to access, analyze, and visualize SSURGO data. These tools enable users to overlay soil data with other spatial datasets for comprehensive land use analysis and planning.
