Cig Gypsum Curtain Project
Pasture Systems & Watershed Management Research
Project Number: 1902-13000-012-11
Nonfunded Cooperative Agreement
Start Date: Oct 01, 2010
End Date: Sep 30, 2014
1. Implement and demonstrate the effectiveness of gypsum curtains for reducing soluble P on farms in Somerset County, Maryland.
(a) Demonstrate effectiveness at a sub-watershed scale.
(b) Demonstrate effectiveness across different soil types in the region.
(c) Evaluate potential adverse environmental impacts.
2. Work in concert with NRCS personnel and other entities to develop standards for this practice.
Stream and ditch monitoring in the study area will be intensified in order to further establish a base line for assessing the effectiveness of this practice. Following six or more months of monitoring, gypsum curtains will be installed, and stream and ditch monitoring methods will be used to measure changes in groundwater, ditch and stream chemistry following filtration.
