The CTIC collects tillage data by conducting surveys about tillage systems \nfor all counties in the United States. Watershed aggregations were done by overlying the 8-digit HUC \npolygons with a raster of county boundaries and a raster of the 2001 National Land Cover Data for land \nuse 82 (cultivated land) to derive a county/land-use area weighting factor. The weighting factor was then \napplied to the county-level tillage data for the counties within each 8-digit HUC and summed to yield the \ntotal acreage of each tillage type within each 8-digit HUC watershed. Tillage systems include three types \nof conservation tillage (no-till, ridge-till, and mulch-till), reduced tillage, and intensive tillage. Total planted \nacreage for each tillage practice for each crop grown is reported to the CTIC. The dataset includes total \nplanted acreage by tillage type for selected crops (corn, cotton, grain sorghum, soybeans, fallow, forage, \nnewly established permanent pasture, spring and fall seeded small grains, and \"other\" crops) for 1989-2004. \nThe CTIC did not collect data nationwide for 1999, 2001, and 2003. In addition, data were not collected for \nall counties every year. Missing data are coded with -9999.\nThe companion WBDHUC8 geospatial dataset is available online: \nhttps://water.usgs.gov/lookup/getspatial?wbdhuc8.xml .", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P92O4VUO", "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.e3205291-aee1-4698-8f69-6efcc3a0c656.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_e3205291-aee1-4698-8f69-6efcc3a0c656", "keyword": ["Conterminous U.S.", "Inlandwaters", "USGS:e3205291-aee1-4698-8f69-6efcc3a0c656", "agricultural land", "crop residue management", "inland waters", "planted acreage", "tillage practice"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-127.886246, 22.885847, -64.623167, 51.602543", "theme": ["geospatial"], "title": "Tillage Practices in the Conterminous United States, 1989-2004--Datasets by Aggregated Watershed; ds573_tillage_lu01"}
