Marketing Manure-Part 1

This is part 1 of a two part series discussing the results of a manure marketing survey conducted by the University of Nebraska.
Livestock enterprises have undergone substantial structural change in recent years, including the concentration of livestock and poultry industry into fewer farms (Council for Agricultural Science and Technology, 1996). There has been a reduction in farms with cattle by 50% and farms with swine by 80% between 1965 and 1995 while numbers of hogs and cattle in inventory has stayed nearly constant (USDA, 1965-1995). Livestock and poultry produce, annually, 3.5 and 3.1 million tons of plant-available nitrogen and phosphorus, respectively, as collectible manure (Council for Agricultural Science and Technology, 1996).
