These data were derived by \ncombining published state pesticide use coefficients published by the\nNational Center for Food and Agricultural Policy (NCFAP) and county\nharvested crop acres available from the 1992 Census of Agriculture.\nA description of the methods used to develop the county database\nis published in USGS OFR 00-250, \"Method for Estimating Pesticide Use\" \nand is available online from: http://pubs.er.usgs.gov/pubs/ofr/ofr00250.\nMaps showing the geographic distribution of use patterns for 199\ncompounds (BT was not mapped) area available from http://ca.water.usgs.gov/pnsp/.\nThe pesticide use estimates contained in this file represent average\nusage patterns for the years 1990-1993 and do not represent a specific\nyear.  The key limitations of the data include the following:\n(1) state use coefficients represent an average for the entire\nstate and consequently do not reflect the local variability of\npesticide management practices found within states and counties,\n(2) pesticide use estimates are not for a specific year, but\nrepresent typical use patterns for a four year period, (3) state\npesticide use coefficients many not have been available for all states\nwhere a pesticide may have been applied to agricultural land,\nand therefore, are not included, and (4) the county crop acreage\nuse to estimate county pesticide use is from the 1992 Census of\nAgriculture and may not represent all crop acreage because of\nCensus nondisclosure rules.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9SQZUMD", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.4dae4270-0b19-401e-80d6-f99533c6e0e8.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_4dae4270-0b19-401e-80d6-f99533c6e0e8", "keyword": ["Census of Agriculture", "NAWQA", "National Water Quality Assessment Program", "USGS:4dae4270-0b19-401e-80d6-f99533c6e0e8", "agricultural pesticide use", "agriculture", "environment", "fumigants", "fungicide", "geoscientificInformation", "harvested crop acres", "herbicide", "inlandWaters", "insecticide"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-127.977, 23.0933, -65.118, 48.283", "theme": ["geospatial"], "title": "1992 County Pesticide Use Estimates for 200 Compounds"}
