Today nearly half the nitrogen atoms in the proteins of an average human being's body came at some time or another through an ammonia factory.
The plan was for OCO's measurements to be synchronised with an analysis of ozone, nitrogen dioxide, methane and other greenhouse gases by the rest of the fleet.
The bodies of Mr Cain, a father of one from Whitehill, and Mr Clarke, from Liss, were found in an apple storage area where nitrogen is used to preserve fruit.
If you're going to be an effective and profitable farmer, nitrogen fertilizers must be applied at every crop cycle.
The combined effect of charging and improved vehicle technology, notably cleaner-burning diesel engines that are being used in more buses and taxis, has led to an overall reduction of 13% in nitrogen oxides and 12% in PM10 via vehicle tailpipe emissions in the charging zone.
Also, the cleaner burning fuel reduces combustion byproducts over petroleum and diesel, cutting carbon monoxide emissions by an estimated 90%-97%, and nitrogen dioxide emissions by 35%-60%.
FORBES: Tough Trucking For Natural Gas Vehicles: Can They Make It In The Long Haul?
When Caesar exhaled, he released an enormous number of "breath" molecules, mostly nitrogen and carbon dioxide.
An important result of that measurement was the discovery of nitrogen on Mars.
He acknowledged that any soil used to grow nitrogen-fixing plants or were fertilised for agricultural reasons would result in an increase in gases involved in the formation of ozone.
Until recently the only equipment for spotting a suitcase bomb was an unwieldy machine the size of a refrigerator, using liquid nitrogen to cool crystal detectors down to 300 degrees below zero and taking hours to produce a reading.
Until recently the only equipment for spotting a suitcase bomb was an unwieldy machine the size of a refrigerator that used liquid nitrogen to cool crystal detectors down to 184 degrees Celsius below zero and took hours to produce a reading.
The residents, for instance, of Kafue, an industrial town that once bustled with workers at its textile and nitrogen factories, now talk of unemployment, the cost of sending children to school and stinking garbage.
They hired a scientist to come up with a formulation of chemicals that delivered nitrogen, potassium and phosphorus in highly water-soluble form, so that an impatient gardener could give plants an instant shot to the leaves, so to speak.
Energy accounts for about three-quarters of the cost of producing nitrogen fertilisers, so cheaper gas and proximity to America's many farmers make Terra an attractive buy.
ECONOMIST: Feeding the world has become a mouth-watering opportunity
Carbon-14 decays into nitrogen at predictable rates, which is how it can be used to determine the age of an object.
