Recent expansion of the swine industry in North Carolina has focused
public attention on manure management issues. Concerns relating to
odors and potential problems from lagoons have received extensive negative
press throughout the state. North Carolina State University is addressing
these problems by evaluating Best Management Practices and alternative
manure handling methods. Current studies have addressed minimizing
odors by aerating lagoons, installing wind breaks adjacent to swine facilities,
and covering lagoons. The viability of commercial systems for treating
manure is also being analyzed. While a moratorium on new lagoons
is in effect and a phase-out of existing lagoons proposed by the governor
provide a short term solution, the future lies in developing a systems
approach that promotes long term nutrient management goals. With
manure management issues receiving national attention, the emphasis is
on protecting soil, air and water quality.
