With regards to the emission level, NH3 and NO3 - released from
farming contributed 27.26% and 65.98% to aquatic eutrophication
for organic tomato production, respectively. NH3 accounted for
26.64% and NO3 for 64.47% of aquatic eutrophication in the conventional
tomato production. This shows that aquatic eutrophication
was dominated by NH3 and NO3 - released during the farming stage.
