Abstract: Liming data processingThe county level data for liming, agricultural and environmental variables was joined with the U.S. county-level shapefile in 2012 Notes for Joining the Datasets Miami-Dade County, Florida: Previously known as Dade County, this county was renamed Miami-Dade County in 1997, and its FIPS code changed from 12025 to 12086.To join with the county-level shapefile, we updated the county FIPS code to the current code (12086).Broomfield County, Colorado: Created in 2001 from parts of Adams, Boulder, Jefferson, and Weld counties, Broomfield County (FIPS 8014) did not exist during the period.Therefore, we assumed its liming application to be 0 for this time frame.Baltimore, MD; St. Louis, MO; and independent cities in Virginia: Independent cities, such as Baltimore, St. Louis, and several cities in Virginia, are administratively independent from any county and are not included in county-level agricultural data from the U.S. Bureau of the Census.Since agricultural data is typically reported at the county level and these independent cities do not have significant agricultural activity, liming application is assumed to be 0 for these regions.1974 Limed Area: The 1974 data do not report limed area (acres).Therefore, for 1974, we interpolated the limed area (acres) and lime application rate (tons per acre) using data from the previous census years, 1969 and 1978.Cropland Area: Cropland area values recorded as 4.000000e+10 are treated as errors and marked as missing values.
