Limited direct impacts of atmospheric CO2
on nitrogen - fixation have been found in soil biological crusts (Billings et al., 2003), but soil microbial activity beneath shrubs has been observed to increase, thus reducing plant - available nitrogen (Billings et al., 2002).

It's 5x better than gasoline or coal
on nitrogen oxides (smog precursor).
But the precise effect of pine bark beetle plagues
on the nitrogen cycle and carbon cycle is highly variable, says a research group led by the University of Idaho, who have used an ecosystem model to simulate outbreaks.
Depending
on nitrogen carryover from previous management, additional fertilizer may be required beyond that provided through cover crop mineralization to maximize corn yield.
At the time, he said «the stunning finding that forests can also feed
on nitrogen in rocks has the potential to change all projections related to climate change,» because it meant there could be more carbon storage on land and less in the atmosphere than climate models say.
Many of the impediments to progress
on nitrogen and phosphorus issues come from a lack of public understanding.
Our paper
on the nitrogen cycle shows, as an example, how human ingenuity, by inventing an artificial «enzyme» that can convert the abundant gas, N2, into ammonium, changed the cycle for that element.
Diverse farms tend to have smaller fields with more edges, which can mean there's a greater buffering effect
on nitrogen runoff by surrounding grasslands or woodlands.»
HANNAH, S.S.; LAFLAMME, D.P. Effect of dietary protein
on nitrogen balance and lean body mass in cats.
The bonnet and bootlid are supported
on nitrogen filled struts.
The assist relies
on a nitrogen - and oil - charged strut to provide consistent operation in cold or warm climates through the entire tailgate swing.
The new hybrid motor has the ability to run for a few kilometers
on nitrogen thatâ $ ™ s compressed by acceleration and braking.
Thus, it is likely that the positive effects of the pulse feeding pattern observed
on nitrogen retention in humans occurred at the muscle level.
These results are complementary to data obtained in elderly humans showing a positive effect of the pulse protein feeding pattern
on nitrogen balance (5).
In general, when energy intake is sufficient to meet energy demand, increasing the protein content of the diet imparts no added influence
on nitrogen retention (12).
You need to be able to hold onto that important element because your muscles depend
on nitrogen in order to stay healthy and productive.
The figure above compares the effect of the protein pulse diet
on nitrogen retention for women in their sixties with the same effect for women in their twenties.
Not only do they cost more, they are also high
on nitrogen content.
As discussed above, one early study examined whether providing 25 % of protein at breakfast and lunch and 50 % at dinner had any impact
on nitrogen balance compared to spreading the protein evenly across the day's three meals; no difference was found.
Influence of protein intake and training status
on nitrogen balance and lean body mass.
The protein quality is measured according to its biological value (BV — unit of measurement used for calculating the amount of protein that the body can absorb and utilize, based
on the nitrogen retention.
The researchers say the work does not hold immediate implications for farmers and gardeners, who greatly rely
on nitrogen in natural and synthetic forms to grow food.
We present a method to achieve general N - body entangling quantum gates between nuclear spins in solid - state platforms based
on nitrogen vacancy centers in diamond or divacancies in silicon carbide.
At the time, he said «the stunning finding that forests can also feed
on nitrogen in rocks has the potential to change all projections related to climate change,» because it meant there could be more carbon storage on land and less in the atmosphere than climate models say.
The ensuing ability to achieve a controlled trade - off between emissive and photocatalytic behavior of CDs depending
on nitrogen atom positioning inside the aromatic domain is expected to bring substantial improvements on their efficiency for on - demand light emission or energy conversion applications.
Disrupted oscillations The researchers focused
on nitrogen — vacancy (NV) centers, imperfections in diamond that arise where an atom of nitrogen and an empty space replace carbon atoms at two neighboring spots in the crystal lattice.
This symbiosis allows plants, such as peas or clover, to grow
on nitrogen - poor soils — and in agriculture it replaces artificial fertilisers.
So the agency should not improve only communication between its researchers who study air and water, but also talk more with scientists at the U.S. departments of agriculture and energy, who also work
on nitrogen pollution, the report finds.
The blue curve is from a previous study, based
on nitrogen measurements.
Humanity depends
on nitrogen to fertilize croplands, but growing global use is damaging the environment and threatening human health.
Based
on the nitrogen, methane and carbon monoxide in Pluto's atmosphere, scientists predicted the dwarf planet's upper atmosphere would be a brisk — 173 ° Celsius.
Newly reported experiments involving rice grown
on nitrogen - poor soil and poplar cuttings put in air with heavy nitrogen should help convince the skeptics.
He adds that only few projects have been implemented and highlights the ones based
on nitrogen injection to maintain pressure in the Cantarell and Ku - Maloob - Zaap complexes and the use of steam at Samaria Neogene to lower the viscosity of extra-heavy oil which allows it to flow with more ease, plus some pilot tests with chemicals and gas fields.
By focusing

on nitrogen - hungry pitcher plants and their relationship with defecating mammals (1 February, p 43).
For this reason, it's important to figure out where — and by how much — farmers can afford to cut back
on their nitrogen fertilizer use.
And work
on nitrogen could reveal which of two pathways is most important in removing biologically fixed nitrogen from oceans.
To assess the influence of phosphorus
on nitrogen removal, the researchers used a comparative approach — they examined the differences between how much nitrogen goes into lakes and how much comes out downstream — coupled with time - series analyses of nitrogen and phosphorus concentration in large lakes.

Question: Will the money raised mostly go to advanced wastewater treatment systems to cut back
on nitrogen discharge, or will developers and their allies in government be able to get at some of the dough to have sewers built and make more money on development?
