EFFECTS OF AGRICULTURAL NUTRIENT MANAGEMENT ON NITROGEN FATE AND TRANSPORT IN LANCASTER COUNTY PENNSYLVANIA1

Abstract: Nitrogen inputs to, and outputs from, a 55‐acre site in Lancaster County, Pennsylvania, were estimated to determine the pathways and relative magnitude of loads of nitrogen entering and leaving the site, and to compare the loads of nitrogen before and after the implementation of nutrient management. Inputs of nitrogen to the site were manure fertilizer, commercial fertilizer, nitrogen in precipitation, and nitrogen in ground‐water inflow; and these sources averaged 93, 4, 2, and 1 percent of average annual nit… Show more

“…Specific yield (Sy) for the WTF method was estimated using a water-budget approach (Walton, 1970;Hall and Risser, 1993;Healy and Cook, 2002). For late fall through early spring, rates of ET in Minnesota are small, and soil-moisture contents are usually at their greatest level.…”

“…The simulated recharge rate was appreciably higher than the 41 percent of annual precipitation estimated for the carbonate-rock terrain of the Conodoguinet Creek Basin for a 5-year period (Becher and Root, 1981). However, the simulated recharge rate was nearly identical to the 53 percent of annual precipitation estimated at an agricultural field site in a carbonate terrain of Lancaster County for a 6-year period (Hall and Risser, 1993).…”

“…Due to the availability of water level data and the simplicity of estimating recharge rates from temporal fluctuations or spatial patterns of water levels, the groundwater recharge can be calculated as follows (Hall and Risser 1993;Healy and Cook 2002;Scanlon et al 2002).…”
