Animal waste management:  Current needs
and future opportunities

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.
