  Description:
    Abstract:
      This data set contains county estimates of nitrogen and
      phosphorus content of animal wastes produced annually for the
      years 1982, 1987, and 1992.  The estimates are based on animal
      populations for those years from the 1992 Census of Agriculture
      (U.S. Bureau of the Census, 1995) and methods for estimating the
      nutrient content of manure from the Soil Conservation Service
      (1992).
      The data set includes several components..
      1. Spatial component - generalized county boundaries in ARC/INFO
      format/1/, including nine INFO lookup tables containing animal
      counts and nutrient estimates keyed to the county polygons using
      county code.  (The county lines were not used in the nutrient
      computations and are provided for displaying the data as a
      courtesy to the user.)  The data is organized by 5-digit
      state/county FIPS (Federal Information Processing Standards)
      code.  Another INFO table lists the county names that correspond
      to the FIPS codes.
      2. Tabular component - Nine tab-delimited ASCII lookup tables
      of animal counts and nutrient estimates organized by 5-digit
      state/county FIPS (Federal Information Processing Standards)
      code.  Another table lists the county names that correspond to the
      FIPS codes.
      /1/ The use of trade names is for identification purposes only
      and does not constitute endorsement by the U.S. Geological
      Survey.
    Purpose:
      These estimates are intended for large-scale ground- and
      surface-water analyses of nutrient sources or changes in these
      sources.  These data on nutrients in manure can be compared to
      fertilizer inputs of nutrients.
    Supplemental_Information:
      The amount of nitrogen and phosphorus present in manure (in
      kilograms) has been calculated for each county of the United
      States.  The procedure is identical to that of Smith and others
      (1997), which covered the year 1987.  Nutrient estimates for the
      years 1982 and 1987 were computed again for the data set here,
      and the results were checked against the results computed
      previously by Alexander (written commun., 1992) for those years
      to ensure that they were identical.
      Limitations..
      The estimates are county level and are based on estimates of the
      nutrient content of animal manure produced per 1,000 pounds of
      animal weight on a daily basis.
      One important limitation of the animal population numbers from
      the Census of Agriculture is that for some counties and animal
      classes, no data are reported. This limitation reportedly is the
      result of restrictions on including animal population data for
      counties where animal production is dominated or limited to one
      business or farm. These data therefore are considered trade
      secrets and may not be included in the county-based data. This
      limitation on population data at the county level results in
      discrepancies when county-based data are summed and compared to
      national animal population totals. At the present we have no way
      of estimating animal populations for those counties with missing
      data and further have no way of determining which counties are
      missing data. Therefore, the animal manure, nitrogen and
      phosphorus estimates for some counties are an underestimate of
      the total nutrient form animal manure in those counties.

        PREPARE COUNTY POLYGON COVERAGE.
        The county polygons are provided for the convenience of users to
        display the data for the conterminous United States and were
        not used in computing the nutrient estimates.  (Although Alaska
        and Hawaii are included in the data base, those county lines are
        not included in the set of polygons.) The county polygons are
        from a generalized version of the 1:2,000,000 Digital Line Graph
        (DLG) series data.  The generalized version was designed for
        page-size display at the 1:34,000,000 scale and does not contain
        some of the smaller county equivalents such as the independent
        cities in Virginia.  Any similar county coverage containing
        5-digit state/county FIPS (Federal Information Processing
        Standards) codes may be substituted by the user.  The FIPS code
        is necessary as a key to the lookup tables of manure data.
        The U.S. Geological Survey Cartography and Publications Program
        prepared the county spatial data in 1988 by generalizing the
        1:2,000,000 county DLG data using ARC/INFO.  Here is the general
        procedure.
        Due to the magnitude of the data to be handled, the country was
        divided into EAST and WEST portions along the Mississippi River
        These regional coverages were again divided into an exterior arc
        coverage, containing those arcs that defined the universal
        polygon and an interior arc coverage.  So as to not generalize
        counties into oblivion and to keep some degree of
        recognizability, interior arcs were treated as if the editing
        scale was 1:17,000,000, while exterior arcs, (those displaying
        the most curvature), were handled at the scale of 1:34,000,000.
        The general ARCEDIT strategy applied to each coverage
        went as follows:
        >- Set cover-id of all arcs to 1
        >- Split arcs along key visual points
        >- Densify arcs with a tolerance of 680 meters (340 meters for
        >  interior arcs)
        >- Generalize arcs at 6800 meters (3400 meters for interior
        >  arcs)
        >- Spline arcs at 680 meters (340 meters for interior arcs)
        >- Generalize arcs at 680 meters (340 meters for interior arcs)
        >- Remove arcs and labels for exterior polygons (islands) with
        >  an area of 185,000,000 sq meters or less
        >- With the use of SNAPCOVERAGE, SNAPFEATURES, and a snapping
        >  tolerance of 1000 meters, snap the nodes of interior arcs to
        >  the arcs of the exterior coverage
        >- Retrieve exterior arcs into interior coverage with the GET command
        >- MAPJOIN sectionals into complete U.S. coverage
        >- Unsplit arcs
        Each polygon (county) has only one label and a valid FIPS Code.
        NOTES:
        1. Some polygons with an area of 185,000,000 square meters or
        less were not deleted due to their importance for county
        identification. Thus, the larger polygons (islands) that
        distinguish the counties of San Juan and Island in the state of
        Washington and the arcs that make up the counties of Kings and
        New York in the state of New York were not eliminated.
        2. For islands within the Great Lakes that are under Canadian
        jurisdiction, a cover-id of 9999 and a FIPS Code of 99999 were
        designated.  However, the Great Lakes themselves were coded
        with a Cover-id of 9999 and a FIPS Code of 90000.
        3. Only the following independent cities of Virginia are
        displayed at this scale: Chesapeake (FIPS code 51550),
        Hampton (51650), Newport News (51700), Richmond (51760),
        Suffolk (51800), and Virginia Beach (51810). [Arlington (51013)
        was added April 1989.]

        small to be displayed at this scale, were incorporated into the

        Certain cattle categories (140002, 140018) were not included in
        the animal wastes estimates because the populations are accounted
        for under other categories.
        140002 = total of all cattle and calves (140018+140052+140068)
        140018 = cows and heifers that have calved (140020+140036)
        Ducks, geese, pigeons, pheasants, quail and other poultry were
        not included in the estimates either.
        Nutrient estimates were based on nutrient content of daily
        wastes produced per 1000 pounds of animal weight, which were
        obtained from the Soil Conservation Service (1992).  The
        estimated animal weights were obtained the from the National
        Agricultural Statistics Service (K. Cavett, verbal
        communication, 1990). Estimates of nutrient content, in some
        cases, represent an average of the reported range of values or
        are assumed values.
        The nutrient estimate for the years 1982, 1987 and 1992 are
        calculated as:
        >Number  * (avg wt / 1000 lbs) * nutrient       * .4536 kg/lb * days
        > of                             content                        per
        >animals                         in                             year
        lbs/day/1000 lbs
        Because 1992 is a leap year, the calculation uses 366 days per
        year as the number of days per year.
        The following SAS program describes how the the estimation
        method was carried out for the state of Wyoming.  The estimates
        were carried out on a state by state basis, and then the results
        were appended for the nation.
        For each State there is a record with a pseudo county code of
        998, "All other counties." This record sums the data that were
        not published because of Census disclosure rules;  no data is
        published that would disclose the operations of an individual
        farm.
        As part of the review of this data set, we learned that
        TURKEY-HENS are a subset of TURKEYS.  Instead of re-running the
        SAS program, we subtracted the estimates for TURKEY-HENS from

  Overview_Description:
    Entity_and_Attribute_Overview:
      Estimates of the total nutrient content of manure by county
      are located in three identically formatted files sorted by
      FIPS (Federal Information Processing Standards) code, with
      one file for each year:
      >MANURE.82 -- 1982 nitrogen and phosphorus totals with
      >           1982 animal populations
      >MANURE.87 -- 1987 nitrogen and phosphorus totals with
      >                1987 animal populations
      >MANURE.92 -- 1992 nitrogen and phosphorus totals with
      >                1992 animal populations
      An example data structure for 1982 is shown below.  The structure
      is the same for the 1987 and 1992 files.

      Estimates of the nitrogen and phosphorus content of manure
      by county and by animal type are located in six identically
      formatted files sorted by FIPS code and organized by
      nitrogen or phosphorus:
      >MANURE.N82 -- 1982 nitrogen
      >MANURE.N87 -- 1987 nitrogen
      >MANURE.N92 -- 1992 nitrogen
      >MANURE.P82 -- 1982 phosphorus
      >MANURE.P87 -- 1987 phosphorus
      >MANURE.P92 -- 1992 phosphorus
      An example data structure for nitrogen for 1982 is shown
      below.  The structure is the same for the 1987 and 1992 files.

  Technical_Prerequisites:
    We have provided two forms of the data set: ARC/INFO export
    format and tab-delimited ASCII format.  The ARC format contains
    the county boundaries as well as the nutrient estimates.  The
    nutrient estimates are in lookup tables keyed by FIPS code.  The
    ASCII version does not contain any county boundaries, just the
    nutrient estimates with county FIPS code as a key.  The user
    must have some kind of automated geographic information system
    (GIS) software to use the ARC/INFO format.  The ASCII version
    can be read into a GIS or into a spreadsheet.
