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.
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.
The Soil Boundaries have been updated to the October 2019 NRCS SSURGO data release.
