With regards to the emission level, the NH3 released during
farming contributed 93.08% and 91.55% to the acidification potential
for the organic and the conventional tomato production,
respectively. The acidification potential of tomato production was
mainly dominated by NH3 and NO3
, accounting for more than 90.00%. Rising use of organic fertilizer increased N losses through
leaching and runoff (Du et al., 2011; Jia et al., 2013).
