- The changing structure of hog farms is altering manure management practices, as larger operations seek to manage nutrients on a limited cropland base. At the same time, strengthening of the Clean Water Act with regard to runoff from manure nutrients, State regulations like the 1997 moratorium on hog farm expansion enacted by North Carolina, and local conflicts over odor are requiring producers to alter their manure management practices. Information about the effects of recent policies and structural changes on manure management technologies and practices, the use of nutrient management plans, and manure application rates is useful for evaluating the effectiveness of environmental policies and determining future policy needs.
