Flooding Frequency, based on soil characteristics, has been updated to the October 2019 NRCS SSURGO data release. Note there is a change to the legend used to depict the data in this update.
Forest Productivity is a measure of wood volume likely to be produced by the most important tree species based on soil characteristics.
Forest Productivity – Top Species/Tree Types depicts the most productive tree species or type based on soil characteristics.
This layer classifies soils types by farmland importance. Important farmlands consist of prime farmland, unique farmland, and farmland of statewide or local importance. Within these classifications, limitations to farmland importance may be noted. See Prime Farmlands Definitions for further information.
Surface Texture is based on the composition of sand, silt, and clay in the surface layer of soil based on the standard soil triangle definition.
The National Commodity Crop Productivity Index, or NCCPI, a rating of the non-irrigated productivity of the soil, has been updated to the October 2019 NRCS SSURGO data release.
Forest Productivity is a measure of wood volume likely to be produced by the most important tree species based on soil characteristics.
Forest Productivity – Top Species/Tree Types depicts the most productive tree species or type based on soil characteristics.
Surface Percent Organic Matter shows the percentage of the surface layer of soil that is comprised of plant and animal residue.
Slope Gradient, depicting the steepness of the landscape by soil type, has been updated to the October 2019 NRCS SSURGO data release.
