USA SSURGO - Farmland Class

The [Farmland Protection Policy Act], part of the 1981 Farm Bill, is intended to limit federal activities that contribute to the unnecessary conversion of farmland to other uses. The law applies to construction projects funded by the federal government such as highways, airports, and dams, and to the management of federal lands. As part of the implementation of this law, the [Natural Resources Conservation Service] identifies high quality agricultural soils as prime farmland, unique farmland, and land of statewide or local importance. Each category may contain one or more limitations such as Prime Farmland if Irrigated. For more information of farmland classification see the [National Soil Survey Handbook].

Units: Classes Cell Size: 30 meters Source Type: Discrete Pixel Type: Unsigned integer Source: [Natural Resources Conservation Service] Update Frequency: Annual Publication Date: December 2025 Data from the [gNATSGO database] was used to create the layer. This layer is derived from the 30m rasters produced by the [Natural Resources Conservation Service] (NRCS). The value for farmland class is derived from the gSSURGO map unit table field Farm Class(farmlndcl). What can you do with this layer? This layer is suitable for both visualization and analysis acrossthe ArcGIS system. This layer can be combined with your data and other layers from the [ArcGIS Living Atlas of the World] in ArcGIS Online and ArcGIS Pro to create powerful web maps that can be used alone or in a story map or other application. Because this layer is part of the [ArcGIS Living Atlas of the World] it is easy to add to your map: * In ArcGIS Online, you can add this layer to a map by selecting Add then Browse Living Atlas Layers. A window will open. Type "farmland" in the search box and browse to the layer. Select the layer then click Add to Map. * In ArcGIS Pro, open a map and select Add Data from the Map Tab. Select Data at the top of the drop down menu. The Add Data dialog box will open on the left side of the box, expand Portal if necessary, then select Living Atlas. Type "farmland" in the search box, browse to the layer then click OK. In ArcGIS Pro you can use the built-in [raster functions] or create your own to create custom extracts of the data. Imagery layers provide fast, powerful inputs to geoprocessing tools, models, or Python scripts in Pro. The [ArcGIS Living Atlas of the World] provides an easy way to explore many otherbeautiful and authoritative maps on hundreds of topics like this one.
