1. OGIC Soils FIT 11/5/2014 Statewide Soils Dataset Status

2. April – Convened OR Soils FIT. NRCS provides status of SSURGO. NRCS proposes SSURGO/STATSGO merge to provide interim statewide layer. September – September – SSURGO and STATSGO: similarities and differences. Presented data viewing and report generation options. NRCS to prepare SSURGO/STATSGO data set for FIT review. 9/22 - GEO hosts merged draft dataset. October – Presentation of statewide merged dataset to FIT. Statewide map examples. Metadata, data element review. 10/27 – second draft uploaded. OGIC Soils FIT Progress 2014

3. Soils FIT reviews current STATSGO/SSURGO product. Determines if additional data elements need to be added to the current attribute table. Based on feedback from the workgroup and from the forum, the framework soils dataset may be modified. The plan is to certify the data standard at the spring OGIC forum. Soils FIT Next Steps

4. National Cooperative Soil Survey Data Products SSURGO - information collected at scales of 1:12,000 to 1:63,360. Mostly 1:24,000 in Oregon. SSURGO - information collected at scales of 1:12,000 to 1:63,360. Mostly 1:24,000 in Oregon. STATSGO2 – commonly called the General Soil Map of the United States. Broad-based inventory of soils at a scale of 1:250,000. STATSGO2 – commonly called the General Soil Map of the United States. Broad-based inventory of soils at a scale of 1:250,000.

Oregon Statewide Soil Survey Dataset Products Spatial Data – File geodatabase with soil map unit polygons from SSURGO, with STATSGO polygons where SSURGO is not available Spatial Data – File geodatabase with soil map unit polygons from SSURGO, with STATSGO polygons where SSURGO is not available Tabular Data – Microsoft Access database with attributes for all SSURGO and STATSGO map units in the spatial data. SSURGO and STATSGO use identical tabular data structure. Tabular Data – Microsoft Access database with attributes for all SSURGO and STATSGO map units in the spatial data.

9. Soil map unit on a mound – intermound landform Depths in inches

11. Dominant Component vs. Dominant Condition Aggregation Method Component Percent of Map Unit Land Capability Class - NIRR Alpha402 Beta353 Gamma253 Dominant Component: Land Capability Class = 2 (40%) Dominant Condition: Land Capability Class = 3 (35 + 25 = 60%) (35 + 25 = 60%) Example Soil Map Unit: Alpha-Beta-Gamma complex, 5 to 20 percent slopes

25. The mapunit and muaggatt tables can be joined directly to the spatial data using the mukey field in both.

26. Create Farmland Class map with mapunit table

27. The mapunit and muaggatt tables can be joined directly to the spatial data using the mukey field in both.

28. Create Nonirrigated land capability class (dominant condition) map with muaggatt table
