The primary purpose of this report was to review the literature and analyze research needs on the effects of land application of animal waste. An additional purpose was to assemble published information on application guidelines for animal waste. Included in this report are information on the characteristics of waste, effects of waste on soil and water near application sites, application rates, application techniques, and research needs. This report is organized into six main topics: Climate, waste, and soil classification; waste composition; effect of waste on the environment; application rates based on waste constituents; application techniques; and research needs. The climate, waste, and soil classification systems were developed to allow comparison of the effects of animal waste applications on land in various parts of the country. The composition of the waste in each climate was tabulated and values compared. Comparisons between climatic regions were not possible because the large variability within regions. Because of this variability no average composition for a given waste in a given climatic region was possible. The effect of the waste on the environment was measured in terms of the possible final disposition of the waste constituents. These constituents could accumulate in the soil, move to the groundwater, runoff the soil surface, or be taken up by plants. Attempts were made to assemble application guidelines from the various parts of the country.
