Animal Manures

Abstract

Wherever animals are raised, manure accumulates. This becomes a surprising amount of material that must be disposed of each year. This manure contains primary (major) nutrients, secondary (minor) nutrients, and micronutrients (trace elements) for plants; organic matter; and water. In addition, it may contain disease organisms and be a source of flies and noxious odors. Where large numbers of animals are housed, disposal of their manure becomes a major problem, especially since quality of the environment is so important to each of us.
