Abstract
The manure that is returned to croplands each year is an important resource in the subsistence farming systems of eastern Kenya. Measurements on several farms han: shown that the manure being used is of very poor quality. Analyses of soil samples from beneath the bOIl/as (small enclosures) where animals are kept llldicate that substantial losses of nutrients occur through leaching; ammonia volatilization and denitrification may also be involved. Current practice is to apply the manure at rates that appear to make poor use of this scarce resource The findings are discussed in terms of what changes to the system ma) be f"t-asible to reduce losses of nutrients, and to improve the quality of the manurc and the effectiveness of its use.
