Summary
Partial Gridded SSURGO (30-meter) extracted to Mississippi River Basin. Includes the following attribute tables: mapunit; muaggatt, valu1. This layer represents soil map unit polygons in a raster format. Each cell value is represented by the integer version of the mapunit key. The standard character mapunit key (MUKEY) is also included so that the raster attribute table can be joined to other soil attribute tables. The national gSSURGO Value Added Look Up (valu1) Table Database that provides ready-to-map themes such as available water storage and soil organic carbon in (11) standard depth layers and zones; crop root zone depths; available water storage in the crop root zone; drought vulnerable soil landscapes; and potential wetland [...]

Purpose
This dataset is being used as part of the Conservation Blueprint 1.0 being developed for the Multi-LCC Mississippi River Basin/Gulf Hypoxia Initiative. The purpose of the Conservation Blueprint is to map, evaluate, and select the most strategic and cost effective places to implement integrated strategies that protect and enhance wildlife habitat while complementing ongoing efforts that reduce nutrient loads to the Gulf of Mexico hypoxic zone and benefit agricultural production through ecosystem services.
The Mississippi River Basin/Gulf Hypoxia Initiative, spearheaded by seven Landscape Conservation Cooperatives, is undertaking a strategic and transparent process to create an integrated framework that supports planning, design, configuration, and delivery of wildlife conservation practices within the watershed. This framework consists of multiple quantitative objectives representing three interests (i.e., wildlife, water quality, agriculture), a tiered set of conservation strategies to achieve those objectives within five production agriculture systems (i.e., corn & soybean; grazing lands; floodplain forest; rice; cotton), and a modeling approach to determine where to best implement those actions within four key ecological systems of the Mississippi River Basin (i.e., headwater row crop fields; upland prairies; mid-sized riparian streams; mainstem floodplains).
The Initiative plans to use this framework to address collaborative needs that will enhance organizational capacity, avoid duplication of effort, streamline prioritization, and align the work of agencies and organizations across multiple scales. This effort is intended to be complementary to related on-going efforts, like the Gulf of Mexico Hypoxia Task Force, Mississippi River Basin Initiative, and state nutrient reduction initiatives, but with an added emphasis on the ecological and social values of wildlife habitat.
