Manure and Nutrient Management

Concern about the impact of nutrient loadings on the environment, that is, the relation of livestock and poultry manure to groundwater contamination, is well- documented both inside the United States (Brown et al., 1989; Frink, 1969; Harris, 1987; Lanyon and Beegle, 1989; Madison et al., 1986; Patni and Culley, 1989; Pinkowski et al., 1985; University of Wisconsin-Extension and Wisconsin Department of Agriculture, Trade and Consumer Protection, 1989; U.S. Congress, Office of Technology Assessment, 1990; Walter et al., 1987; Young et al., 1985) and outside the United States (Adams and McAllister, 1975; Phillips et al., 1982; Steenvoorden, 1986; Webster and Goulding, 1989).

RESOURCE UTILIZATION OR WASTE DISPOSAL

A little more than 50 years ago, animal manures were considered a tremendous asset in providing fertility to U.S. soils. The 1938 yearbook of agriculture stated:

One billion tons of manure, the annual product of livestock on American farms, is capable of producing $3,000,000,000 worth of increase in crops. The potential value of this agricultural resource is three times that of the Nation's wheat crop and equivalent to $440 for each of the country's 6,800,000 farm operators. The crop nutrients it contains would cost more than six times as much as was expended for commercial fertilizers in 1936. Its organic matter content is double the amount of soil humus annually destroyed in growing the Nation's grain and cotton crops (U.S. Department of Agriculture, 1938:445).
