Selected chemicals, solids, and microorganisms that are used in agriculture or produced as by-products of agriculture in the United States as of 2009

This data set brings together and categorizes many of the chemicals, solids, and microorganisms that are used in agriculture or produced as by-products of agriculture in the United States (as of 2009). Each entry in the data set includes the name, Chemical Abstracts Service Registry Number, purpose(s) in agriculture, and a reference. For pesticides and their degradates, the pesticidal use, parent pesticide, and the United States Environmental Protection Agency Pesticide Chemical Code are included. The data were compiled as part of a U.S. Geological Survey study to improve the understanding of field-scale and watershed-scale hydrology and the environmental behavior of individual chemicals. The goals of the study were to provide a foundation of understanding for making optimal management decisions and to help set the expectations of water quality improvements which can result from changes in agricultural management and policy decisions.
