Abstract
A lysimeter study in combination with ^<15>N-tracer method was carried out for 3 years and 9 months to investigate the fate of nitrogen derived from cattle manure sawdust compost and coated fertilizer which were applied to vegetables grown in upland Andosol. Of total amount of input nitrogen derived from cattle manure sawdust compost, 1.15% was leached as nitrate, 12.8% was taken up by plants, 68.1% remained in soil, and 18.0% was unaccounted-for which was estimated to be the result of denitrification and volatilization. Of total amount of input nitrogen derived from coated fertilizer, 2.55% was leached as nitrate, 65.3% was taken up by plants, 16.2% remained in soil, and 15.9% was unaccounted-for which was estimated to be the result of denitrification and volatilization.
