Estimated annual agricultural pesticide use for counties of the conterminous United States, 2008-12 Estimated annual agricultural pesticide use for counties of the conterminous United States, 2008-12
Annual county-level pesticide use was estimated for 423 herbicides, insecticides, and fungicides applied to agricultural crops grown in the conterminous United States during 2008–12. For all States except California, pesticide-use data were compiled from proprietary surveys of farm operations located within U.S. Department of Agriculture Crop Reporting Districts (CRDs). Surveyed...

Water quality in Indiana: trends in concentrations of selected nutrients, metals, and ions in streams, 2000-10 Water quality in Indiana: trends in concentrations of selected nutrients, metals, and ions in streams, 2000-10
Water quality in Indiana streams generally improved during the 2000–10 study period, based on trends in selected nutrients, metals, and ions. This study combined water-quality data from the Indiana Fixed Station Monitoring Program (FSMP) with streamflow data from nearby U.S. Geological Survey streamgages. A parametric time-series model, QWTREND, was used to develop streamflow-adjusted...

Annual agricultural pesticide use for Midwest Stream-Quality Assessment, 2012-13 Annual agricultural pesticide use for Midwest Stream-Quality Assessment, 2012-13
This report provides estimates of annual agricultural use of 190 pesticide compounds for counties and selected watersheds of Midwestern States for 2012 and 2013 compiled for subsequent analysis by the National Water-Quality Assessment Program, Midwest Stream-Quality Assessment (MSQA). One of the goals of MSQA is to characterize contaminants at perennial-stream sites throughout the Corn...

Preliminary estimates of annual agricultural pesticide use for counties of the conterminous United States, 2010-11 Preliminary estimates of annual agricultural pesticide use for counties of the conterminous United States, 2010-11
This report provides preliminary estimates of annual agricultural use of 374 pesticide compounds in counties of the conterminous United States in 2010 and 2011, compiled by means of methods described in Thelin and Stone (2013). U.S. Department of Agriculture (USDA) county-level data for harvested-crop acreage were used in conjunction with proprietary Crop Reporting District (CRD)-level...

Selected historic agricultural data important to environmental quality in the United States Selected historic agricultural data important to environmental quality in the United States
This report and the accompanying tables summarize some of the important changes in American agriculture in the form of a timeline and a compilation of selected annual time-series data that can be broadly related to environmental quality. Although these changes have been beneficial for increasing agricultural production, some of them have resulted in environmental concerns. The...
