The database also includes runoff and erosion rates; soil test P; tillage practices; planting and harvesting rates and practices; fertilizer application rate, method, and timing; manure application rate, method, and timing; and livestock grazing density and timing. In total, over 1800 individual runoff events \u2013 ranging in duration from 0.4 to 97 hr \u2013 have been included in the database. Event runoff P losses ranged from less than 0.05 to 1.3 and 3.0 kg P/ha for dissolved and total P, respectively. The data contained in this database have been used in multiple research studies to address important modeling questions relevant to P management planning. We provide these data to encourage additional studies by other researchers. </p><div><br>Resources in this dataset:</div><br><ul><li><p>Resource Title: PLEAD Database - Excel.</p> <p>File Name: PLEAD_2018-11-16.xlsx</p><p>Resource Description: Includes data spreadsheets for: Land Use, Soil Data, Soil Chem Data, Inorganic P Application, Grazing Data, Organic P Application, Tillage, Irrigation, Planting, Harvesting, Runoff Data, Sampling Info, Runoff Collection Notes, Daily Weather Data, Weather Stations, Other Notes, Contact Info.</p></li><br><li><p>Resource Title: PLEAD Database Data Dictionary.</p> <p>File Name: PLEAD_data_dictionary.csv</p><p>Resource Description: Defines the column headers/variables, units, and data type represented in each spreadsheet.</p></li></ul><p></p>", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/44526686", "format": "xlsx", "mediaType": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "title": "PLEAD_2018-11-16.xlsx"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/44526689", "format": "csv", "mediaType": "application/csv", "title": "PLEAD_data_dictionary.csv"}], "identifier": "10.15482/USDA.ADC/1482380", "keyword": ["ARS", "NP212", "P Loss in runoff Events from Agricultural fields Database", "PLEAD", "Phosphorus loss", "Phosphorus modeling", "data.gov"], "license": "https://www.usa.gov/publicdomain/label/1.0/", "modified": "2025-11-21", "programCode": ["005:040"], "publisher": {"@type": "org:Organization", "name": "Agricultural Research Service"}, "spatial": "{\"type\": \"MultiPolygon\", \"coordinates\": [[[[-94.0138, 36.2061], [-94.0138, 36.239], [-93.8878, 36.2335], [-93.9426, 36.0911], [-93.9645, 35.7625], [-94.4903, 35.757], [-94.5505, 36.102], [-94.3917, 36.102], [-94.3917, 36.1404], [-94.3369, 36.1404], [-94.3314, 36.2171], [-94.0138, 36.2061]]], [[[-83.279, 33.4841], [-83.279, 33.4841], [-83.2461, 33.3964], [-83.1859, 33.391], [-83.164, 33.3526], [-83.1475, 33.3088], [-83.2516, 33.2595], [-83.2735, 33.1883], [-83.4269, 33.1828], [-83.5473, 33.1719], [-83.5364, 33.4348], [-83.279, 33.4841]]], [[[-95.498, 38.7365], [-95.0544, 38.7365], [-95.0654, 38.3914], [-95.2351, 38.3914], [-95.509, 38.3914], [-95.509, 38.4352], [-95.5035, 38.7365], [-95.498, 38.7365]]], [[[-93.0444, 39.7059], [-92.8581, 39.7004], [-92.6884, 39.7004], [-92.6938, 39.6128], [-92.7048, 39.3225], [-92.7924, 39.3444], [-92.8472, 39.2239], [-92.9348, 39.2294], [-92.9184, 39.2568], [-92.9567, 39.3115], [-93.0553, 39.3225], [-93.1046, 39.3827], [-93.121, 39.4156], [-93.2306, 39.4375], [-93.2251, 39.4704], [-93.247, 39.443], [-93.2744, 39.4594], [-93.2853, 39.5361], [-93.2525, 39.5416], [-93.2799, 39.6182], [-93.2689, 39.7059], [-93.0444, 39.7059]]], [[[-92.1407, 40.3029], [-91.949, 40.3029], [-91.949, 40.259], [-91.9544, 39.9469], [-91.9983, 39.9523], [-92.2885, 39.9523], [-92.3433, 39.9523], [-92.3433, 40.04], [-92.3488, 40.3029], [-92.1407, 40.3029]]], [[[-90.4538, 33.8127], [-90.1799, 33.8072], [-90.1854, 33.7689], [-90.2949, 33.7524], [-90.3114, 33.7141], [-90.2785, 33.6922], [-90.2402, 33.736], [-90.1361, 33.7196], [-90.1306, 33.6758], [-90.1032, 33.6484], [-90.1306, 33.6046], [-90.1032, 33.6046], [-90.1032, 33.4567], [-90.1744, 33.4183], [-90.1744, 33.3307], [-90.3223, 33.3745], [-90.2785, 33.3417], [-90.3333, 33.3033], [-90.3771, 33.2814], [-90.3661, 33.2376], [-90.4154, 33.2376], [-90.4538, 33.265], [-90.4538, 33.3307], [-90.4538, 33.8127]]], [[[-82.4081, 35.4722], [-82.3643, 35.4612], [-82.3315, 35.4996], [-82.2657, 35.4667], [-82.2603, 35.3955], [-82.3479, 35.286], [-82.3534, 35.1929], [-82.3917, 35.2148], [-82.441, 35.1655], [-82.5725, 35.1436], [-82.6217, 35.3024], [-82.7477, 35.4229], [-82.671, 35.4612], [-82.5396, 35.4229], [-82.4081, 35.4722]]], [[[-98.0667, 32.5092], [-97.9462, 32.2353], [-97.8641, 32.0874], [-98.0065, 32.0162], [-98.2091, 31.9177], [-98.2529, 31.9779], [-98.3296, 31.9396], [-98.5487, 32.2627], [-98.472, 32.301], [-98.4775, 32.5146], [-98.0667, 32.5092]]]]}", "title": "Data from: Development of PLEAD: a database containing event-based runoff P loadings from agricultural fields"}
