Description:
Abstract:
This data set contains county estimates of nitrogen and phosphorus content of animal wastes produced annually for the year 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).
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.

Attribute_Accuracy_Explanation:
Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modelling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our webpage at: http://geoplan.ufl.edu/education.html. These data are based on interpretation of available information and should not be construed as legally binding.

Attribute_Accuracy_Explanation:
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. The use of trade names is for identification purposes only and does not constitute endorsement by the U.S. Geological Survey.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
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.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
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.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
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.

Process_Description:
This data was downloaded in ARC/INFO Export Interchange file format by GeoPlan from the Georgia GIS Data Clearing House in 2001. Data was reprojected to FGDL Albers HPGN and clipped from the SE Region to the State of Florida. When received, data was in Albers projection, Datum: NAD27, Spheroid: Clark1866, Units: Meters.
Process_Date: 2002
Process_Step:
Process_Description:
GeoPlan, during the QA/QC process included the following aspects: 1.) Upcased all character records 2.) Reprojected data to FGDL Albers HPGN (See "Map Projection Parameters" below) 3.) Data was clipped to the State of Florida 4.) Added DESCRIPT item based on the County name 5.) Dropped old coverage internal items: MANURE92FL#, MANURE92FL-ID, MANURE92_, MANURE92_I 6.) Dropped AREA and PERIMETER items, the values were incorrect.
