Ammonia volatilization losses from prilled urea, urea supergranules (USG) and coated USG in rice fields

K. Sudhakara; Rajendra Prasad

SummaryAbout 8.4 per cent of applied nitrogen was lost as ammonia during a week after application when prilled urea was broadcast or banded and incorporated in soil 20 days after sowing of rice. Ammonia volatilization was reduced to 3.3 per cent when urea supergranules (USG) were used. Coating of USG with DCD or neem cake showed no advantage. Ammonia volatilization was only 0.7 to 1.6 per cent when fertilizer was applied at panicle initiation stage of rice; highest values were again obtained with prilled urea. The experiments were carried out in closed cages.
