Bibliography: "Readings on Manure Management"
The Water Quality Information Center at the National Agricultural Library has produced a bibliography: "Readings on Manure Management", produced for Animal Residuals 2002: Agricultural Animal Manure Management, Policy and Technology, a conference held last May in Arlington, Virginia. Available on the web at: www.nal.usda.gov .
NRAES has a publication on how they work, type of systems, designs, construction, gas utilization, gas storage, safety, and management. It is a 72 page publication costing $10.
Construction of the Manure Storage
Size the storage for about 180 days of long-term storage in cold climates. This provides winter storage when fields are not accessible and for summer when crops may be present. An estimated waste production of 2.4 cu ft per day per horse would require 432 cu ft of storage for each stalled horse. Base sizing figures on estimates that reflect the specific stable's management.
Management Strategies for Nitrogen
Minimize moisture contamination of manure, compost manure to a stable end point, implement rapid drying technologies. Weeds in Manure Manure has been a major contributor to weed problems where it has been applied to cropland. In pastures, weed infestations may be the result of overgrazing rather than manure application.
Because of global economic forces, swine farms are becoming fewer in number and larger in size. People who live near these operations are understandably concerned about a large operation's odor and its potential effect on water quality. When correctly stored and applied to cropland, nutrients contained in liquid manure can improve soil fertility without affecting ground water. However if stored in unsafe structures or applied incorrectly, liquid manure can potentially pollute waterways.
