I was being sarkasticSkipjack, CO2 is out? News to me.
CO2 is out, now its the Nitrogen

This is a bunch of crap, the article clearly forgets to mention that all the nitrogen extracted to manufacture nitrogen fertilizers is in fact extracted from the AIR.
There is no net addition of Nitrogen to the atmosphere coming from nitrogen based fertilizers manufacturing, on the contrary, there is a slightly reduction due to the fact that not all Nitrogen present in the fertilizers gets back in the atmosphere as "N", but is held in the ground in different compounds.
These type of articles should be banned from any respectable scientific news website.

I think you miss the... political elegance... of this pivot. The nitrogen cycle has absofrakalutely NOTHING to do with atmospheric composition. It is a way to preserve the "Save the Earth! via massive centralized controls" agenda while dropping all the baggage of AGW.Giorgio wrote:This is a bunch of crap, the article clearly forgets to mention that all the nitrogen extracted to manufacture nitrogen fertilizers is in fact extracted from the AIR.

The H-B Process' increase in planetary fixed nitrogen (several hundred percent over 100 years) is a far larger effect than arguing about a few hundredths of a percent of atmospheric composition. The fixed nitrogen supply effects ecology (plants and animals) directly and immediately, not indirectly over century time scales via assumed climatic effects.

Reactive nitrogen, nitrates, are not the same as atmospheric nitrogen.Giorgio wrote:This is a bunch of crap, the article clearly forgets to mention that all the nitrogen extracted to manufacture nitrogen fertilizers is in fact extracted from the AIR.
djolds1, AGW doesn't affect the ecological system as much as it would affect a billion or so port-living peoples. Trees like CO2, retirees won't like the ocean in their house (stupid example since they'd be dead, w/e).
Science is what we have learned about how not to fool ourselves about the way the world is.
Reactive nitrogen used in fertilizer production and the majority of nitrates is manufactured by fractional distillation of plain air which accounts for more than 99% of world nitrogen production.Josh Cryer wrote:Reactive nitrogen, nitrates, are not the same as atmospheric nitrogen.Giorgio wrote:This is a bunch of crap, the article clearly forgets to mention that all the nitrogen extracted to manufacture nitrogen fertilizers is in fact extracted from the AIR.

Nitrogen is taken from air, injected in ground and rejected as Nitrogen at the end of the cycle, no Nitrogen addition in the air in this cycle.
Unless you are talking about NO and NO2 emissions, but than we should talk about internal combustion engines as a main producer for NO and NO2 emission, and not fertilizer manufacturing.
Yes. Al Gore's recently purchased waterfront property in San Francisco really drives home how endangered the coastal living communities are.Josh Cryer wrote:djolds1, AGW doesn't affect the ecological system as much as it would affect a billion or so port-living peoples.

Again, atmospheric gasses (including gaseous nitrogen) are a non-issue on this topic. Flood local or regional ecologies with large quantities of fertilizer (well above what nature was able to historically provide) and you will see effects above and beyond a tripling of crop yields. Some of those effects will be negative, and those negative effects you can latch onto and scream about.
Its really a very elegant political pivot. The only possible "problem" at issue is the H-B Process, which is indisputably a human artifact.

That's exactly my point, ammonia is the precursor to manufacture fertilizers.djolds1 wrote:Plain N2 is not usable by the biosphere until it is "fixed" into ammonia.Giorgio wrote:Reactive nitrogen used in fertilizer production and the majority of nitrates is manufactured by fractional distillation of plain air which accounts for more than 99% of world nitrogen production.

When I said "injected into earth" I was saying it in a figurative way (spread over the land as fertilizer). Sorry if that was not clear

Engineering is the art of making what you want from what you can get at a profit.
Concerning nitrogen and AGW. This is mostly about nitrous oxide (N2O) which is released mostly by soil bacteria in anaerobic conditions turning NO3 to N2 via intermediates like N2O. N2O is also produced when NH4 is nitrified to NO3 under aerobic conditions. Some N2O escapes and has a high global warming potential. Somewhere like 300 times more effective than CO2 over its lifetime.
With extra NO3 or NH4 fertilizer more N2O is released. N2O is on track to become more important than methane in radiative forcing.
With proper application and management of synthetic or animal fertilizer a lot of these potential problems will get less.

Well. Then. CO2 is out and NO2 is in. It is amazing that after 30 years of work the scientist got it wrong. Not to worry. No need to change the goal (UN control of everything), just change the reason.cybrbeast wrote:Concerning nitrogen and AGW.

I guess that if energy control is out of the question then food control is the next best thing.

...Sorel’s work is best characterized by his by his original interpretation of Marxism, which was deeply anti-determinist, politically anti-elitist, anti-Jacobin, and built on the direct action of unions, the mobilizing role of myth—especially that of the general strike—and on the disruptive and regenerative role of violence.

I don't see how CO2 is 'out'. Even though N2O has a much higher global warming potential than CO2 the concentrations are much less, ppb instead of ppm. So if you take into account the atmospheric concentrations, CO2 still has a much higher radiative forcing than N2OMSimon wrote:Well. Then. CO2 is out and NO2 is in.

The main part of the problem is all the pig and chicken shit that is not properly utilized in the industrial system. In past eras this was useful for the gunpowder and military industrys, ammonium nitrate and potassium nitrate were the basis of black powder and other explosives. With the end of carpet bombing and naval battles, and massive high intensity warfare, there is much less demand from these industries.Aero wrote:Its not so simple as that. The part that washes to the Gulf of Mexico is the residual, left after the crop plants have eaten their fill. Without that residual margin crop production suffers, and the first thing to go away is profit.
When I was a kid, we bought some extra farm land, took it over after it was planted to corn. The seller applied commercial nitrogen fertilizer and had fertilized it well. The new land produced about 100 bushels per acre. The next year we planted it back to corn using standard cow manure as fertilizer. The same land produced 35 bushels per acre.
This shows how dependent we are on nitrogen fertilizer. Without it most of us would starve to death in the first year. Or maybe it's the second year, but to soon in any case.
Skipjack - You don't need to hold your bowels, you are confusing nitrogen with methane.
The pig and chicken manure problem is the main issue, it gets left in settling ponds that leaches through the soil or overflows retaining walls, and into the rivers.
Now that they've cultured artificial meat, in the coming decades I think we will see industrial agriculture get away from large industrial farms of millions of live animals and go to brewing up meat in vats for the masses.
