Demystifying the USDA Web Soil Survey: A Comprehensive Overview

The USDA Web Soil Survey (WSS) is a publicly accessible online resource developed and maintained by the Natural Resources Conservation Service (NRCS), an agency of the United States Department of Agriculture (USDA). It provides detailed soil maps and associated data for over 95% of the counties in the United States and continues to expand its coverage. It’s more than just a map; it’s a comprehensive database of soil properties, interpretations, and limitations.

At its heart, the WSS is built upon decades of soil surveys conducted by soil scientists across the country. These surveys involve extensive field investigations, laboratory analyses, and data interpretation to characterize the different soil types present in a given area. The results are compiled into detailed soil maps, which delineate areas with similar soil characteristics, and associated reports, which provide information on soil properties, such as texture, drainage, slope, and potential uses.

The WSS represents a significant advancement over traditional paper-based soil surveys. It offers several key advantages, including:

• Accessibility: The WSS is available online, 24/7, from any location with an internet connection.
• Up-to-dateness: The WSS is continuously updated with new data and information, ensuring that users have access to the most current soil information available.
• Interactive mapping: The WSS allows users to create custom soil maps for their specific area of interest.
• Comprehensive data: The WSS provides access to a wide range of soil data, including physical, chemical, and biological properties.
• Interpretations and limitations: The WSS provides interpretations of soil data for a variety of uses, such as agriculture, construction, and recreation, as well as identifying potential limitations.

The ongoing development and refinement of the WSS reflect the NRCS’s commitment to providing the best possible soil information to the public. Recent advancements have focused on improving the accuracy and resolution of soil maps, expanding the range of available data, and enhancing the user interface to make the WSS more intuitive and user-friendly.

Leveraging SoilWeb: A Mobile Companion to the Web Soil Survey

Exploring Key Features of the USDA Web Soil Survey

The USDA Web Soil Survey is packed with features designed to provide users with comprehensive soil information. Here’s a breakdown of some of the most important ones:

1. Area of Interest (AOI) Selection

The first step in using the WSS is to define your Area of Interest (AOI). This is the geographic area for which you want to retrieve soil data. The WSS offers several methods for defining your AOI, including:

• Address or PLSS coordinates: Enter an address or Public Land Survey System (PLSS) coordinates to quickly locate your area of interest.
• Interactive map: Use the interactive map to zoom in to your area of interest and draw a polygon to define your AOI.
• Import shapefile: Import a shapefile containing the boundaries of your area of interest.

The ability to define your AOI precisely ensures that you only retrieve the soil data that is relevant to your specific needs. This saves time and effort by eliminating the need to sift through irrelevant information.

2. Soil Map Tab

Once you have defined your AOI, the Soil Map tab displays a detailed soil map of the area. The map shows the different soil types present in the AOI, with each soil type represented by a unique map unit symbol. Clicking on a map unit symbol will display information about the corresponding soil type, including its name, description, and acreage within the AOI.

The Soil Map tab also allows you to customize the map display by changing the base map, adding labels, and adjusting the transparency of the soil map units. This allows you to create a map that is tailored to your specific needs and preferences.

3. Soil Data Explorer Tab

The Soil Data Explorer tab is where you can access detailed information about the soil properties and characteristics within your AOI. This tab is divided into several subtabs, each providing access to a different type of soil data.

• Suitabilities and Limitations for Use: This subtab provides information on the suitability and limitations of the soils in your AOI for a variety of uses, such as agriculture, construction, and recreation.
• Soil Properties and Qualities: This subtab provides information on the physical, chemical, and biological properties of the soils in your AOI, such as texture, drainage, slope, organic matter content, and pH.
• Soil Reports: This subtab allows you to generate a variety of reports containing detailed information about the soils in your AOI.

4. Shopping Cart

The Shopping Cart feature allows you to select and download the soil data and reports that you need. You can add individual soil properties, interpretations, and reports to your shopping cart and then download them in a variety of formats, such as PDF, CSV, and shapefile.

This feature streamlines the process of obtaining soil data by allowing you to select only the information that is relevant to your needs. This saves time and effort by eliminating the need to download and process large datasets.

5. Interpretations and Reports

The WSS provides a wealth of interpretations and reports that can help you understand the suitability and limitations of the soils in your AOI for various uses. These interpretations are based on the soil properties and characteristics and are designed to provide practical guidance for land management decisions.

For example, the WSS provides interpretations for agricultural uses, such as crop suitability, irrigation requirements, and erosion potential. It also provides interpretations for construction uses, such as building site development, septic system suitability, and road construction. These interpretations can help you make informed decisions about how to use and manage your land.
