2012 Annual Report
In FY 2012 the following activities took place. Under objective 1, we led the development of a white paper prioritizing manure management needs in the Chesapeake Bay Watershed. This consensus document, published in Journal of Soil and Water Conservation, included input from industry, conservation, government and university experts. Under objective 2, we published findings summarizing five years of intensive watershed monitoring in ARS’s Mahantango Creek watershed, highlighting the spatial variability and transient nature of nitrogen and phosphorus runoff (hot moments and hot spots), yet pointing to significant opportunities for cover cropping and reduced tillage to control nutrient losses not just in the Mahantango Creek watershed, but across the Ridge and Valley province of the Chesapeake Bay watershed. Under objective 3, we published a series of articles summarizing the state-of-the science in trapping phosphorus in runoff water, reviewing the performance of gypsum-based ditch filter for phosphorus, and describing the properties of spent gypsum, to assess its potential as a soil amendment. Under objective 4, a series of articles were developed describing the Mahantango Creek watershed database, which includes 40 years of continuous flow and precipitation monitoring, and over 30 years of water quality data. Under objective 5, we published a proof-of-concept paper describing the use of empirical runoff models to develop a next-generation site assessment tool (the Fertilizer Forecaster) for nitrogen and phosphorus. We demonstrated that readily-available weather forecast variables can be used to predict runoff over short time intervals, helping farmers to assess when and where to apply fertilizers and manures.
