The photographs were captured as part of a long-term (2012\u201320) investigation conducted by the USGS in cooperation with the Great Lakes Restoration Initiative and the U.S. Department of Agriculture Natural Resources Conservation Service to evaluate the effectiveness of selected conservation practices\u2014 cover crops and variable rate technology\u2014at reducing sediment and nutrient losses from agricultural fields. The camera images documented field management activities. Photographs were used to corroborate the dates and times of producer actions such as planting, harvesting, tillage, fertilizer application, and aerial seeding of winter wheat. This verification supported the development of a time line of management practices, which helped interpret changes in runoff volume and water-quality responses measured at paired surface-runoff and subsurface-tile monitoring sites.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13DGNAD", "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.6a43ec721ba49b97f88a8793.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6a43ec721ba49b97f88a8793", "keyword": ["Findlay", "Hancock", "Hancock county", "Ohio", "USGS:6a43ec721ba49b97f88a8793", "agricultural sites", "agriculture", "cover crop", "farm", "row crop", "swale"], "modified": "2026-09-08T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-83.655396, 40.846671, -83.651962, 40.848602", "theme": ["geospatial"], "title": "Time-lapse Photographs of Edge of Field site near Findlay, OH 2017\u20132020"}
