Predicting Nitrogen Mineralization from Livestock Manure (5.49 MB)

A paper written by John Andrews that includes a review of the factors influencing mineralization of nitrogen from livestock manure, and identifies important considerations for accurately modeling this process. John may be contacted at john.andrews@co.usda.gov.

Silage Leachate

This is a set of links to technical documents about preventing silage leachate pollution. Thanks to Joseph Neafsey for collecting this material and making it available.

ODOR - The Issue for the New Decade

Livestock production does produce odors, and there is no way to eliminate those odors entirely... Fortunately, there are a number of management practices that can be implemented to reduce odor problems.

Calibrating a Manure Spreader

Manure spreaders have been used for many years to apply manure to agricultural fields. With the increased emphasis water quality and nutrients in runoff from non-point sources it is important to know how much manure a spreader is applying over a given area.

Composting Along Roadways

In some parts of the country manure availability exceeds the amount of agricultural land available to properly recycle manure nutrients (1). Clearly, alternative uses of manure are needed. The use of manure-based compost along the nation's roadways to establish and nurture vegetation is one of those alternatives.

Composting and Erosion Control References

The following references, while relating to composting of biosolids (sludge), make a good case for the use of compost in erosion control activities.

Amercian Society of Agricultural Engineers (ASAE)

The discussion that follows describes the analysis process used to relate manure nutrient availability to the land resource.

County Level Analysis of Land-Based Manure Utilization  

Part of the recent NRCS resource assessment mandated by the Resource Conservation Act (RCA) included a national assessment of manure nutrients available for crop and pasture fertilization...

The Phosphorus (P) Index

In 1990, the United States Department of Agriculture (USDA) Soil Conservation Service (now USDA Natural Resources Conservation Service or USDA-NRCS) formed a national work group of scientists from Universities, Cooperative Extension, and the USDA Agricultural Research Service to develop a P indexing procedure that could identify soils, landforms, and management practices with the potential for unfavorable impacts on water bodies because of P losses from agricultural soils.

State of the Land -- Manure Nutrients Relative to the Capacity of Cropland and Pastureland to Assimilate Nutrients

Spatial and Temporal Trends for the United States: Data from the Census of Agriculture were used to estimate livestock populations, quantities of manure produced, and land available for manure application for 1982, 1987, 1992, and 1997. Livestock include beef cattle, dairy cattle, swine, and poultry. A descriptive analysis is presented of the temporal and spatial changes in the number, size, and kind of livestock operations, and the changes in animal units, quantity of manure nutrients produced, land available for manure application, and excess manure nutrients at both the farm level and the county level.
