Description:
This CA Storie Index dataset is from the USDA SSURGO soils database; the dataset was clipped to a buffered boundary of Ventura County, California.


The Storie Index is a soil rating based on soil properties that govern a soil's potential for cultivated agriculture in California.

The Storie Index assesses the productivity of a soil from the following four characteristics: Factor A, degree of soil profile development; factor B, texture of the surface layer; factor C, slope; and factor X, manageable features, including drainage, microrelief, fertility, acidity, erosion, and salt content. A score ranging from 0 to 100 percent is determined for each factor, and the scores are then multiplied together to derive an index rating.

For simplification, Storie Index ratings have been combined into six grade classes as follows: Grade 1 (excellent), 100 to 80; grade 2 (good), 79 to 60; grade 3 (fair), 59 to 40; grade 4 (poor), 39 to 20; grade 5 (very poor), 19 to 10; and grade 6 (nonagricultural), less than 10.

These data are the Official soil survey data for Ventura County compiled from the USDA, NRCS Web Soil Survey, Soil Survey Geographic (SSURGO) Database. Areas included in this layer also include parts of Kern County, San Luis Obispo County, Kern County, and Los Angeles County.
