Abstract EN
Smallholder farmers in Kenya collect manure from confined cattle housing termed zero-grazing units.
Zero-grazing designs may include urine collection, though the effectiveness of these designs in improving manure N content has not been established.
The manure-urine mixtures produced in these units were simulated to determine urine effects on manure N composition.
Manure and manure-urine mixtures were stored for 120 days during dry and rainy seasons in Kenya.
Manure-urine mixtures leached 26% of their mineral N content during the dry season, but only 12% during the rainy season.
After storage, manure-urine mixtures had less organic-N and fiber-N than manure alone during the dry season (P<0.01), but not during the rainy season.
Results suggest that the effect of cattle urine on manure N composition is greater during dry seasons than rainy.
Manure should not be stored more than 30 days to minimize N loss to leaching.
Farmers may take steps to reduce N loss by controlling leaching and protecting manure from rainfall.
