How much nitrogen is in wheat?
Nitrogen performs many vital functions in the wheat plant. Wheat requires 2 to 2.5 pounds of nitrogen (N) per bushel (bu) of grain, or, if grazed, 1 pound per acre or each 3 pound-per-acre animal gain. Shortages of N may cause reduced tillering, reduction in head size, poor grain fill and low protein content.
What is nitrogen used for?
Nitrogen Uses. It is used in the manufacture of ammonia, to produce nitric acid and subsequently used as a fertilizer. Nitric acid salts include important compounds like potassium nitrate, ammonium nitrate, and nitric acid. Nitrated organic compounds such as nitro glycerine are often explosives.
What is the role of nitrogen in life?
Preservation of bodies and reproductive cells and stable storage of biological samples also makes use of liquid nitrogen. Nitrogen makes up 78 percent of the Earth ‘s atmosphere and is a part of all living tissue. Nitrogen is a crucial ingredient of life, since it is a constituent of DNA and as such is part of the genetic code.
What is the seventh element in the periodic table?
The seventh element of the periodic table between carbon and oxygen is Nitrogen. It’s an important part of amino acids. Around eighty percent of the Earth’s atmosphere comprises nitrogen gas. It has no colour, mostly diatomic non metal gas along with odourless and colourless in nature.
How many steps are there in the nitrogen cycle?
When it returns to the soil from a decaying plant it can be used again by another plant. Nitrogen Cycle. The nitrogen cycle has five general steps. Nitrogen fixation.
Where is nitrogen found in the soil?
It is found in nitrates and nitrites in soil and water. All these substances are part of the nitrogen cycle and interconnected. Industrial companies emit nitrogen extensively, increasing nitrite and nitrate content in the ground and water, being the consequence of reactions in the nitrogen cycle.
How is nitrogen extracted?
Nitrogen is extracted through a process called fractional distillation from liquefied air.
Is nitrogen a part of DNA?
Nitrogen is a crucial ingredient of life, since it is a constituent of DNA and as such is part of the genetic code. Nitrogen molecules often exist in soil. Nitrogen can be present in nitrates and nitrites in water and in soils. These compounds are all part of the nitrogen cycle and both are interconnected.
How much nitrogen is in the air?
Nitrogen makes up almost 80 percent of air, but that N may be used by the plant only after it is fixed, or taken from the air, industrially or by certain soil bacteria in association with legumes. The total amount of N in soil is large. In Pennsylvania, soil N averages about 0.14 percent, or about 2,800 lb/ acre.
Why does rain water carry nitrates?
Rain water, in excess of what can be held by well-drained soils, leaches down through the soil profile and will carry nitrate with it because nitrate is negatively charged and is not held by the like-charged soil particles. Ammonium has a positive charge and thus is held to soil particles, securing it from being leached. The potential loss of N by leaching is greatest in winter and spring months in well-drained soils.
What is the N recommendation?
The N recommendation is made for the yield level you specify or for an average yield potential based on soil type if the yield goal is not indicated. Actual farm yields vary quite a bit from the average for a soil type, so the yield goal can help tailor recommendations to your farm conditions.
Why is mineral N important to soil?
However, because mineral N is sensitive to environmental factors, a chemical analysis of soil before planting cannot indicate the N availability other than right at the time the sample was taken and , therefore, is unable to predict soil N availability throughout the growing season.
How does N fertilizer work?
Inorganic N fertilizers supply N in a readily available mineral form. Regardless of the form in which it is applied, the actions of soil bacteria convert mineral N to the nitrate form, beginning several days after application or when the so il temperature exceeds 50°F . If they are properly applied, the various N fertilizers are equally effective. Choice, therefore, can be based on the cost per unit of N and your fertilizer N management plan. (See "Comparing Fertilizer Materials", and the Penn State Agronomy Guide for more information.)
Can urea be used as N?
Use of urea fertilizer as an N source can result in N losses if the fertilizer is not incorporated. This includes urea and urea-ammonium nitrate solution fertilizer (UAN). Loss of urea N due to volatilization may be eliminated by immediate mechanical or rain incorporation (Table 1). Because of the volatilization problem, no-till corn production requires more attentive fertilizer management. Non-urea N fertilizers are not usually subject to volatilization under Pennsylvania soil conditions.
Is preplant compatible with sidedress?

Overview
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 …
History
Nitrogen compounds have a very long history, ammonium chloride having been known to Herodotus. They were well known by the Middle Ages. Alchemists knew nitric acid as aqua fortis (strong water), as well as other nitrogen compounds such as ammonium salts and nitrate salts. The mixture of nitric and hydrochloric acids was known as aqua regia (royal water), celebrated for its ability to dissolve
Properties
A nitrogen atom has seven electrons. In the ground state, they are arranged in the electron configuration 1s 2s 2p x2p y2p z. It therefore has five valence electrons in the 2s and 2p orbitals, three of which (the p-electrons) are unpaired. It has one of the highest electronegativities among the elements (3.04 on the Pauling scale), exceeded only by chlorine (3.16), oxygen (3.44), and fluorine(3.98…
Occurrence
Nitrogen is the most common pure element in the earth, making up 78.1% of the volume of the atmosphere. Despite this, it is not very abundant in Earth's crust, making up only 19 parts per million of this, on par with niobium, gallium, and lithium. The only important nitrogen minerals are nitre (potassium nitrate, saltpetre) and soda nitre (sodium nitrate, Chilean saltpetre). However, these ha…
Production
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 oxygenfor steelmaking and other purposes. Whe…
Applications
The applications of nitrogen compounds are naturally extremely widely varied due to the huge size of this class: hence, only applications of pure nitrogen itself will be considered here. Two-thirds (2/3) of nitrogen produced by industry is sold as the gas and the remaining one-third (1/3) as the liquid.
The gas is mostly used as an inert atmosphere whenever the oxygen in the air …
Safety
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…
