Experiments are recommended for western Canada to confirm that deep banding of N fertilizer, as is commonly used by actual farms employing zero till, reduces nitrous
oxide emissions compared to surface incorporation.
Not exact matches
We could not find any studies in western Canada which
compared - nitrous
oxide emissions from pulse crops such as lentils, peas or chick peas, with nitrous
oxide emissions from cereals such as spring wheat.
We did not find to date any published studies which
compared the effects of type of tillage system and nitrogen fertilizer placement method on nitric
oxide emissions.
These experiments would
compare nitrous
oxide emissions from pulse crops such as peas and lentils with nitrous
oxide emissions from cereals such as wheat and barley.
While these forgotten gases account for only a small fraction of total greenhouse gas
emissions from deforestation, nitrous
oxide is up to 300 times more effective at trapping heat in the atmosphere when
compared to carbon dioxide over a 100 - year time period.
This review would include determining how these nitrous
oxide emissions from zero tillage systems
compared with those from conventional tillage, and identifing gaps in knowledge requiring further experiments and studies.
When
compared with pure electric vehicles that use coal - generated electricity, H600's
emission of sulfide, nitrogen
oxide, and particle matter is 0.17 %; 0.67 %; and 50 % of the latter, respectively (a typical coal power plant emits 272 grams of PM when generating one kWh of electricity).
We used the US Environmental Protection Agency's (EPA's) detailed CMAQ model to project
emissions for sulfur dioxide and nitrogen
oxides to calculate changes in air quality under each scenario in 2020
compared to business as usual.
Burning the fuel produces no sulfur, less carbon monoxide, and fewer nitrogen
oxides, particulates, and other
emissions,
compared with petroleum diesel.
The move toward Tier 4 is made up of a 45 percent reduction in the
oxides of nitrogen
emissions compared to the current Tier 2 standard and an 85 percent reduction in particulate matter
emissions based on preliminary analysis.
In addition, the exhaust
emissions of sulfur
oxides and sulfates (major components of acid rain) from biodiesel are essentially eliminated
compared to diesel.»
For example, according to the National Energy Technology Laboratory (NETL), a new pulverized - coal plant (operating at lower, «subcritical» temperatures and pressures) reduces the
emission of NOx (nitrogen
oxides) by 86 percent, SO2 (sulfur dioxide) by 98 percent, and particulate matter by 99.8 percent, as
compared with a similar plant having no pollution controls.
