How are the agricultural soils grouped?
The soil groupings are based on the NRCS Land Capability Classification System. This system measures the limitations of soils using eight classes. Class I being the least limited and VIII being the most restrictive. The sub class describes the type of limitation be it W-water, E-erosion, and S-shallow or unstable soils. NRCS has published, or is in the process of publishing, a soil survey for each county in Arkansas. Within these surveys each soil is described and is designated a capability class and a subclass. The surveys also contain aerial photographs that depicts where soils are located within the county.
