Estimates of inorganic nitrogen deposition from precipitation for selected Chesapeake Bay Watersheds This dataset contains estimates of the yearly sum of nitrogen atmospheric deposition of inorganic nitrogen in selected Chesapeake Bay watersheds from 1985-2012. Data for 1985-2012 were downloaded from the National Atmospheric Deposition Program.

Values are derived from data based on National Climatic Data Center (NCDC) climate divisions, of which there are 344 in the U.S. Categories: Data; Types: Citation; Tags: Chesapeake Bay, Delaware, James River, Maryland, New York, All tags...

Values are derived from a slightly-modified version of the National Inventory of Dams (NID) 2013 dataset, for which approximately 10% of records had the dam completion date estimated.

Data are available for other crops; however, these three were chosen because wheat is a traditional crop that has been grown for a long time in the Basin and corn and soybeans have increased in recent times because of wetter conditions, the demand for biofuels, and advances in breeding short-season, drought-tolerant crops. The data come from the National Agricultural Statistics Service (NASS) Census of Agriculture (COA) and have estimates for 1974, 1978, 1982, 1986, 1992, 1997, 2002, 2007, and 2012. Years with missing data were estimated estimated using multivariate imputation... Categories: Data; Types: Citation; Tags: Crookston, Emerson, Fargo, Halstad, Kindred, All tags...
