The Ag Data Commons is migrating

The Ag Data Commons is migrating to a new institutional portal on Figshare. The current system is available for search and download only. The new platform is open for submission with assistance from Ag Data Commons curators. Please contact NAL-ADC-Curator@usda.gov, if you need to publish or update your datasets.

Fragment Modifier Calculator

    The Fragment Modifier Calculator is an Excel spreadsheet allowing the user to generate the textural fragment modifier based on percentages of fragments and parafragments. This calculator is from the [National Soil Survey Handbook Part 618, Subpart B, Exhibit 618.90](https://directives.sc.egov.usda.gov/OpenNonWebContent.aspx?content=29282.wba).
