Agricultural Research Service (ARS) soil scientists are studying sediments in water channels to understand their role in phosphorus absorption during a manure spill.
During a manure spill, sediments in a contaminated water channel can capture phosphorus from the manure and release the nutrient back into the water — sometimes for months on end — at levels exceeding U.S. Environmental Protection Agency (EPA) criteria.
According to an article in the March 2013 issue of Agricultural Research, the research team's results using a simulated manure spill and clean-up efforts suggest that current approaches to remediating manure spills need improvement.
Fortunately, the team also gleaned some ideas about where to start looking for those improvements.
