Effects of urea levels on ammonia gas emission from soil [a NH3 emission, b accumulated NH3-N, Urea level: 0.005 g/soil g (1/4 N), 0.01 g/soil g (1/2 N), 0.02 g/soil g (N) and 0.04 g/soil g (2 N)]. Error bar indicates standard deviation (n = 3; mean ± SD). Different letters indicate significant difference according to Duncan’s multiple range test (DMRT) (p < 0.05)
