Sentences with phrase «if nitrogen emission»

That means the emission probability for excited CO2 (and water vapor) is significantly greater than zero and explains the observed emission spectra which show strong CO2 (and water vapor) emission spectral features rather than the continuum emission that would be expected if nitrogen emission dominated.

Not exact matches

Emissions of nitrous oxide may be calculated if the nitrogen fertilizer or manure use during farming is known.

«Nobody really knows how much [nitrogen trifluoride] is used... we don't know how much is being produced and also don't [know if the emissions rate] is correct,» says Ray Weiss, a geochemist at the Scripps Institution of Oceanography at the University of California, San Diego, who led the new work.

Resource - conserving cropping practices from WHEAT, such as more targeted use of nitrogen fertilizers or sowing wheat into untilled soils and crop residues, can raise wheat farmers» incomes while curbing greenhouse gas emissions, if widely adopted, he added.

The effect of the pulse crop on the nitrous oxide emissions from a following cereal should also be measured, since it is known that nitrogen fertilizer requirements of wheat and barley are reduced if they follow a pulse crop in the rotation.

According to the Department of Energy, if the transportation sector switched to natural gas, it would cut the nation's carbon - monoxide emissions by at least 90 percent, carbon - dioxide emissions by 25 and nitrogen - oxide emissions by up to 60.

If the premise of a well - mixed 78/21 nitrogen / oxygen ratio is thrown out, then taking the proxy at face value, these are maps of thermal emission by oxygen.

In particular, if focuses on the following areas: reducing methane emissions from ruminant animals by modification of plant composition; reducing nitrous oxide emissions by making the use of nitrogen more efficient both in terms of going from soil to plant and in the animal; enhancing carbon sequestration through plant breeding; reducing emissions from fertiliser production.

While acidic rain fall would indeed go away if emissions were reduced significantly the impact from acid rain is thought to be much longer term with recovery of soils taking some time to occur due to sulfur and nitrogen storage.

But Increases Ones Which Cause Acid Rain The bad news is that if you take the entire lifecycle of a CO2 - burying plant — the «cradle to grave» pollution which takes into account the extra energy required mine additional coal and bring it to the power plant — emissions of nitrogen oxide and sulfur oxides were 40 % greater than a modern coal plant not set up to capture carbon.
