How much nitrogen is in liquid fertilizer?
There are 4 quarts in a gallon, so 9 pounds divided by 4 is 2.25 pounds of fertilizer liquid in 1 quart. Your product is 16 percent nitrogen by weight, so 16/100 = 0.16, and 0.16 x 2.25 is 0.36. This means that 1 quart of fertilizer supplies 0.36 pounds of nitrogen.
What is N-P-K stand for?
In short, fertilizers are labeled N, P or K to indicate their nutrient content in terms of nitrogen (N), phosphorus (P), and potassium (K). All three are important for plant growth.
Where did the word nitrogen come from?
The English word nitrogen (1794) entered the language from the French nitrogène, coined in 1790 by French chemist Jean-Antoine Chaptal (1756–1832), from the French nitre ( potassium nitrate, also called saltpeter) and the French suffix -gène, "producing", from the Greek -γενής (-genes, "begotten").
How many electrons does a nitrogen atom have?

What are some examples of dinitrogen complexes?
The first example of a dinitrogen complex to be discovered was
How is nitrogen gas produced?
Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption ). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk delivered nitrogen. Commercial nitrogen is often a byproduct of air-processing for industrial concentration of oxygen for steelmaking and other purposes. When supplied compressed in cylinders it is often called OFN (oxygen-free nitrogen). Commercial-grade nitrogen already contains at most 20 ppm oxygen, and specially purified grades containing at most 2 ppm oxygen and 10 ppm argon are also available.
What is the name of the mixture of nitric and hydrochloric acids?
The mixture of nitric and hydrochloric acids was known as aqua regia (royal water), celebrated for its ability to dissolve gold, the king of metals. The discovery of nitrogen is attributed to the Scottish physician Daniel Rutherford in 1772, who called it noxious air.
Why do we use nitrogen in aircraft fuel?
In some aircraft fuel systems to reduce fire hazard (see inerting system ). To inflate race car and aircraft tires, reducing the problems of inconsistent expansion and contraction caused by moisture and oxygen in natural air. Nitrogen is commonly used during sample preparation in chemical analysis.
What is the nitrogen cycle?
The nitrogen cycle describes movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere.
Most fertilizers contain the three elements nitrogen, phosphorus and potassium. The ratio between these elements in the product is called the N-P-K rating and is usually expressed as three numbers separated by dashes — 10-6-4, for example. The first number is the nitrogen content.
To find the nitrogen content of a fertilizer, multiply the number in the N position of the N-P-K rating by the total weight of the fertilizer. If the N-P-K rating is 10-6-4, for example, and the weight of the bag of fertilizer is 25 pounds, the fertilizer bag contains 2.5 pounds of nitrogen. The one unit of nitrogen in this case would be 1 pound.
Which unit you use to measure nitrogen content isn't important as long as you are consistent. Pounds are the most common unit, but you could use grams instead if you prefer. A unit of nitrogen fertilizer is just one unit of whichever unit you choose to describe the nitrogen content.
How much does UAN32 weigh?
UAN32 weighs 11.06 pounds per gallon, for a calculation of 11.06 pounds x 0.32 = 3.5 pounds.

Is ammonia a gas or a liquid?
Anhydrous ammonia is a gas but a liquid under pressure. The liquid converts back to a gas once it leaves the manifold. Ammonia is quite easy to calculate because you are dealing with weight not liquid so the calculation works the same as for urea. Ammonia has an analysis of 82-0-0.

Chemistry and compounds
Atomic nitrogen, also known as active nitrogen, is highly reactive, being a triradical with three unpaired electrons. Free nitrogen atoms easily react with most elements to form nitrides, and even when two free nitrogen atoms collide to produce an excited N2 molecule, they may release so much energy on collision with even such stable molecules as carbon dioxide and waterto cause …

Although nitrogen is non-toxic, when released into an enclosed space it can displace oxygen, and therefore presents an asphyxiation hazard. This may happen with few warning symptoms, since the human carotid body is a relatively poor and slow low-oxygen (hypoxia) sensing system. An example occurred shortly before the launch of the first Space Shuttle mission on March 19, 1981, when two technicians died from asphyxiation after they walked into a space located in the Spac…
