Manure Treatment Technologies
Chesapeake Bay Program.
"This report focuses on six broad categories of treatment technologies: Thermochemical Processing, Composting, Anaerobic Digestion, Settling, Mechanical Solid Liquid Separation, and Wet Chemical Treatments. The ability to reduce nitrogen by volatilization and to separate both nitrogen and phosphorous to a stream that is likely to be utilized off-farm is quantified for each technology. Transformation of nutrients to more plant-available forms is also discussed for each technology."

A bibliography of 142 citations from the NAL catalog (AGRICOLA) covering 2000-2001. Prepared for "Animal Residuals 2002: Agricultural Animal Manure Management, Policy and Technology" (May 6-8, 2002).

Confined Animal Production and Manure Nutrients
USDA. Economic Research Service.
"Census of agriculture data were used to estimate manure nutrient production and the capacity of cropland and pastureland to assimilate nutrients." Discusses relationships between manure nutrients produced and land available for application at the county level.

Trends in the Potential for Nutrient Loading from Confined Livestock Operations
USDA. Natural Resource Conservation Service.
"Using farm-level census, presents county estimates of pounds of manure nitrogen and phosphorus potentially generated from confined livestock, and compares these estimates to the potential for nitrogen and phosphorus uptake/removal by crops and application on pastureland."

Animal Feeding Operations
EPA. National Pollutant Discharge Elimination System.
"NPDES program regulates the discharge of pollutants from point sources to waters of the United States. Concentrated Animal Feeding Operations (CAFOs) are point sources, as defined by the CWA [Section 502(14)]."

Comprehensive Nutrient Management Planning (CNMP)
USDA. Wisconsin NRCS.
The development of a comprehensive nutrient management planning (CNMP) begins with a comprehensive engineering and conservation planning resource assessment of current site conditions. Management options and structural alternatives are developed to address resource concerns identified during the assessment.
