The Soil Survey Geographic Database (SSURGO)

The Soil Survey Geographic Database, commonly known as SSURGO, is a comprehensive resource that provides detailed information about soil characteristics across the United States. Managed by the USDA's Natural Resources Conservation Service (NRCS), this database plays a crucial role in various fields, from agriculture to environmental management. 🌱

What is SSURGO?

SSURGO is a collection of soil survey data that has been gathered over the last century through the National Cooperative Soil Survey. This extensive database includes both map data and tabular data, making it a valuable tool for anyone interested in understanding soil properties. The information is accessible for most areas in the U.S., including territories and commonwealths.

Key Features of SSURGO

One of the standout features of SSURGO is its detailed attribute data. Here’s a closer look at what you can find:

1. Soil Characteristics: Information about available water capacity, soil reaction, and electrical conductivity.
2. Land Use Data: Yields for various land types such as cropland, woodland, rangeland, and pastureland.
3. Environmental Limitations: Insights into limitations affecting recreational development, building site development, and engineering uses.
4. Flood Frequency: Data regarding the frequency of flooding in different areas.

How to Access SSURGO Data

Accessing SSURGO data is straightforward. Users can view the information through the Web Soil Survey or download it in ESRI® Shapefile format. This flexibility allows for easy integration into GIS applications or databases like Microsoft® Access®. The geographic coordinate systems used in SSURGO make it compatible with various mapping tools, enhancing its usability for researchers, planners, and landowners alike.

Applications of SSURGO Data

The applications of SSURGO data are vast. Here are a few areas where it is particularly beneficial:

1. Agriculture: Farmers can utilize soil data to make informed decisions about crop selection and management practices.
2. Environmental Planning: Urban planners and environmentalists can assess soil conditions to guide sustainable development.
3. Research: Academics and scientists rely on SSURGO for studies related to soil health, ecology, and climate change.
4. Recreation: Understanding soil types can help in planning recreational areas, ensuring they are safe and enjoyable.

Conclusion

In summary, the Soil Survey Geographic Database (SSURGO) is an invaluable resource that offers a wealth of information about soil across the United States. Whether you’re a farmer, researcher, or urban planner, SSURGO provides data that can inform decisions and promote sustainable practices. With its easy accessibility and comprehensive data sets, it’s a tool that continues to support various sectors in understanding and managing soil resources effectively. 🌍
