The manure data were estimated based on\ncounty-level population data of livestock, poultry, and other\nanimals. See the user manual for detailed data sources and\ncleaning methods. 'usfertilizer' utilized the tidyverse to\nclean the original data and provide user-friendly dataframe.\nPlease note that USGS does not endorse this package.
