Gronberg and Norman E. Spahr, U.S. Geological Survey 2012 U.S. Geological Survey Scientific Investigations Report 2012-5207 Reston, VA U.S. Geological Survey http://pubs.usgs.gov/sir/2012/5207/ This data set contains county-level estimates of nitrogen and phosphorus from fertilizer, for both farm and nonfarm uses, for the conterminous United States, for 1987 through 2006. State-level farm and nonfarm nitrogen and phosphorus were derived from the Association of American Plant Food Control Officials (AAPFCO) commercial fertilizer sales data. State estimates were then allocated to the county-level using fertilizer expenditure as county weights for farm fertilizer, and population density as county weights for nonfarm fertilizer. The U.S. Geological Survey, National Water-Quality Assessment program requires nutrient input for analysis of the national and regional assessment of water quality. Detailed information on nutrient inputs to the environment are needed to understand and address the many serious problems that arise from excess nutrients in the streams and groundwater of the Nation. This data set provides estimates of nonpoint nitrogen and phosphorus associated with fertilizer for the conterminous United States for 1987 through 2006. The data is provided as two tables, tblFarmNonfarmCountyNitrogen and tblFarmNonfarmCountyPhosphorus, in a Microsoft Access data file, sir2012-5207_county_fertilizer.mdb. Limitations: County raster data sets Two county raster data sets (referred to as "grids") were utilized in processing the data, because of changes to the county boundaries occurring between 1990 and 2001. Although changes occurred throughout the time period, these changes were implemented at the end of 2001. The 1990 county grid was used for 1987 through 2001; the 2001 county grid was used for 2002 through 2006. Census Bureau data sets Adjustments were made to the population data to correspond to the 1990 county grid (for 1987-2001) and the 2001 county grid (for 2002-2006). 1) Clifton Forge, VA (51560) independent city was incorporated into Alleghany, VA (51005) effective July 1, 2001; Clifton Forge was treated as if it existed through 2001. 2) South Boston, VA (51780) was incorporated into Halifax, VA (51083) effective June 30, 1995; South Boston was treated as if it existed through 2001. 3) Broomfield, CO (08014) was created from Adams (08001), Boulder (08013), Jefferson (08059), and Weld (08123) effective November 15, 2001; Broomfield was treated as if it was created in 2002. 4) Yellowstone National Park, MT (30113) annexed to Gallatin (30031) and Park (30067) counties effective November 7, 1997, but Yellowstone only reported a very small population amount through 1990. No adjustments to population were made. Effects on the fertilizer data: 1) Nonfarm data for Clifton Forge, VA (51560) and South Boston, CA (51780) ends in 2001; data fields are "blank" for 2002 through 2006. 2) Nonfarm data for Broomfield, CO (08014) starts in 2002; data fields are "blank" for 1987 through 2001. 3) Nonfarm data for Yellowstone National Park, MT (30113) ends in 1990; data fields are "blank" for 1991 through 2006. Census of Agriculture data sets Data are included for any county from which $1000 or more of agricultural products are sold, or normally would have been sold during the census year. However, data for some counties are not included because Census non-disclosure rules prohibit disclosing information for an individual farm. Fertilizer expenditure is derived from the following Census of Agriculture items (definitions are in parentheses). 1987 and 1992: Commercial fertilizer (The expense for commercial fertilizer is the amount spent on fertilizer including the cost of custom application.) 1997: Commercial fertilizer (The expense for commercial fertilizer is the amount spent on all forms of fertilzier including rock phosphate and gypsum. It also includes the cost of custom application.) 2002: Fertilizer, lime, and soil conditioners (The expense for fertilizer is the amount spent on all forms of fertilizer and lime including rock phosphate and gypsum during 2002. It also includes the cost of custom application. In the 1997 census, lime expenses were collected and published in the all other production expenses category.) For data collection purposes, counties or statistically equivalent entities are combined with the adjacent or surrounding county, by the Census of Agriculture. 1) For Maryland, the independent city of Baltimore is included in Baltimore County and the state equivalent of District of Columbia is included in Montgomery County (1997) and in Prince George's County (2002). 2) For Missouri, the independent city of St. Louis is included in St. Louis County. 3) For Montana, Yellowstone National Park is included in Park County (1997). 4) For Virginia, most independent cities are included in a surrounding county or in an adjacent independent city. These county data were used "as is" with no attempt to allocate the values to the original counties. Farm data fields are left "blank" for these counties. AAPFCO data set Fertilizer sales are reported by county if available. However the AAPFCO data is used, summarized to the state level. There is no reported fertilizer sales data for Arkansas in 1989, therefore farm and nonfarm data fields are "blank" for Arkansas for 1989.

The 1990 county grid was used to derive county areas for 1987-2001; the 2001 county grid was used for 2001-2006. County areas were derived by summing grid cells for each county (by FIPS 5-digit county code) from the 30-meter-county grids. The sums were multiplied by 900 square meters, and then divided by 1,000,000 to get area in square kilometers. 2005 Census of Agriculture fertilizer expenditure for 1987, 1992, 1997, and 2002 were obtained from U.S. Department of Commerce (1995), U.S. Department of Agriculture, National Agriculture Statistics Service (1999 and 2004) (G.P.

Sacramento CA 95819 (916) 278-3095 gpthelin@usgs.gov Population data for 1987 through 2006 were downloaded from U.S. Census Bureau (2003, 2004a, 2004b, 2008), and Hitt (1992). 2008 Population data were adjusted to correspond to the 1990 county grid (for 1987-2001) and the 2001 county grid (for 2002-2006). Clifton Forge, VA (51650) independent city was incorporated into Alleghany, VA (51005) effective July 1, 2001; Clifton Forge was treated as if it existed through 2001. Census Bureau reported 2000 population of 4289 for Clifton Forge; no estimate was made for 2001. Census Bureau reported 2000 population of 12926 for Alleghany, and 2001 estimated population of 17050. For 2001, subtracted 4289 from Allegehany population of 17068, to get population of 12779. South Boston, VA (51780) was incorporated into Halifax, VA (51083) effective June 30, 1995; South Boston was treated as if it existed through 2001. Census Bureau reported 1990 population for South Boston and Halifax. Population and population estimates are provided for 1991-1999 and 2000-2001 for Halifax but not South Boston. 1990 South Boston population of 6997 was used 1990 through 2001; this amount was subtracted from the Halifax population for the same years. Broomfield, CO (08014) was created from Adams (08001), Boulder (08013), Jefferson (08059), and Weld (08123) effective November 15, 2001; Broomfield was treated as if it was created in 2002. 2000 population was not reported by the Census Bureau. Estimates were provided for 2001-2006. For 2001, Broomfield population was distributed to the other 4 counties in proportion to the area of the original counties that made up Broomfield. See Supplemental_Information for more information. 2008 Fertilizer expenditure data were interpolated as described in Gronberg and Spahr (2012). 2008 1985-2001 commercial fertilizer sales data obtained from the American Plant Food Control Officials (AAPFCO) (B.C. Ruddy, USGS, written commun. 2003). 2002-2004 data obtained in 2005. 2005-2006 data obtained in 2008. 2008 State-level farm and nonfarm nitrogen and phosphorus calculated from fertilizer sales data. State estimates allocated to the county-level using fertilizer expenditure as county weights for farm fertilizer, and population density as county weights for nonfarm fertilizer.
