Mississippi River Basin Gridded SSURGO Hydric Classification – Presence "hydclprs". An indication of the proportion of the map unit that is hydric, based on the hydric classification of individual map unit components.

The Gridded SSURGO National Commodity Crop Productivity Index (NCCPI), version 2.0, arrays soils according to their inherent capacity to produce dryland (nonirrigated) commodity crops. Most of the NCCPI criteria relate directly to the ability of soils, landscapes, and climates to foster crop productivity. A few criteria relate to factors that can limit use of the land (e.g., surface boulders). All criteria used in the index affect crop culture and production and are referred to as factors affecting inherent productivity. Higher values represent higher capacity for production. Extent: Mississippi River Basin. IN ORDER TO CREATE A MANAGEABLE FILE SIZE, THE ORGINAL DATA WAS MULTIPLIED BY 100, THUS VALUES RANGE FROM...

Mississippi River Basin Gridded SSURGO mapunits with at least 5% organic matter (generalized calculation using soil organic carbon values in the 0-20 cm horizon; assuming that bulk density is 1.4 g/cubic meter and that organic matter is 58% carbon).

Mississippi River Basin Gridded SSURGO potential wetland soil landscapes (PWSL version 1) - the percentage of the map unit (all components) that meet the criteria for a potential wetland soil landscape. For version 1 (pwsl1), those soil components that meet the following criteria are tagged as PWSL and their comppct_r values are summed for each map unit. Soil components with hydricrating = 'YES' are considered PWSL. Soil components with hydricrating = “NO” are not PWSL. Soil components with hydricrating = 'UNRANKED' are tested using other attributes, and will be considered PWSL if any of the following conditions are met: drainagecl = 'Poorly drained' or 'Very poorly drained' or the localphase or the otherph data...
This map shows soil factors that may contribute to wind or water erosion, derived from STATSGO and SSURGO soil data and slope information.

Mississippi River Basin Gridded SSURGO mapunits where "pwsl1pomu" (wetland potential) is at least 60 or at least 50 and "drclassdcd" (Drainage Class - Dominant Condition) is poorly or very poorly drained. These mapunits represent those with the highest wetland potential based on these criteria.
