Experimental farmlets at DairyNZ’s Prototype Farm near Hamilton were used to determine potential reductions in nitrous oxide (N2O) emissions from use of a nitrification inhibitor and a restricted grazing regime. A control farmlet was managed under a conventional rotational grazing regime, while a “tight nitrogen” farmlet was managed under a similar grazing regime to that on the control farmlet,...

This paper analyses the correlation between automobile exhaust, PM2.5, and air pollution to explore rate of contribution exhaust PM2.5 effect government regulation on gas. The results show that atmosphere is hazy car main cause pollution. divides governance strategy into two methods: reducing number motor vehicles emissions capacity vehicles. It also effects congestion control public travel est...

Agricultural soils are important sources of atmospheric N2O and CO2. However, in boreal agro-ecosystems the contribution of the winter season to annual emissions of these gases has rarely been determined. In this study, soil N2O and CO2 fluxes were measured for 6 years in a corn-soybean-wheat rotation in northeast China to quantify the contribution of wintertime N2O and CO2 fluxes to annual emi...

conclusions results of this study showed that the screen3 software is one of the popular models for estimating the distribution of air pollutants. nitrogen dioxide emissions are highly regulated in most industrialized regions. decreased emissions from fuel combustion, the use of scrubbers and filters that absorb pollution can be very useful for reduction and control of nitrogen dioxide emission...
