We estimate that EPA's CAFO final rule on manure application would have different impacts on dairy farms in the region, assuming that the farms would maintain the same herd size and same crop production practices. Some farms in the region would be able to comply it on their current land base,...

Nutrients from livestock and poultry manure are key sources of water pollution. Ever-growing numbers of animals per farm and per acre have increased the risk of water pollution. New Clean Water Act regulations compel the largest confined animal producers to meet nutrient application standards...

Recent trends in livestock concentration in major corn producing states suggest that increasing risk of water pollution from manure applications may be offsetting declines in risk of water pollution from chemical fertilizer. Analysis of data from ARMS surveys found that potential excess nitrogen...

Recent trends in livestock concentration suggest that there may be an increasing risk of water pollution from manure applications. These trends in livestock operations may be offsetting improvements in commercial fertilizer management that have the potential to reduce the risk of water...

Replaced with revised version of paper 03/08/04.

EPA's new restrictions on land application of manure nutrients by concentrated animal feeding operations (CAFOs) could decrease the net return of 6-17% of the medium and large dairy farms with lagoon systems in the southwestern United States. Many of the other dairy CAFOs in the region could...

Corn production uses over 25 percent of the Nation's cropland and more than 40 percent of the commercial fertilizer applied to crops. Thus, corn farmers' choices of soil, nutrient, and water management systems can have a major impact not only on their own profitability, but also on the...

Recent policies implemented to protect water-quality encourage improved management of land-applied manure. The significant potential cost of transport and land application has heightened interest in the off-farm processing of animal waste. This paper examines the potential for expansion in...

A Chesapeake Bay Watershed manure management model estimates the minimal regional cost of land applying manure at $110 to $130 million, depending on crop producer's willingness to accept manure and the nutrient standard enforced. Annualized capital costs of existing industrial plants indicate...
