### element:

Nitrogen
* All nitrogen is sourced from people's diets.
* More nitrogen is generated through metabolism
  - lost from crop residue than tilled soil
  - means more rotting carcasses
* Most nitrogen combines with elements
  - other elements
* Most nitrogen comes from air
  - in the form of protein but some comes from nucleic acids
  - consumed by cattle part of the protein the animal consumes
  - is present in dead organic matter below the ground surface
  - produces growth
  - requires for nutrition
* NitroGEN new generation in sports performance nutritional supplements.
* Some nitrogen affects bacterial growth
* Some nitrogen combines with oxygen
  - water
  - comes from proteins
* Some nitrogen excretes in manure
  - urine
* Some nitrogen has bonds
  - effects
* Some nitrogen has strong bonds
  - triple bonds
* Some nitrogen is fixed by lightning and ultraviolet rays
  - lost to the atmosphere by the action of denitrifying bacteria
* Some nitrogen is produced by clover
  - soybeans
  - white clover
  - released by the erosion of nitrate-rich rocks
  - needs for growth
  - returns in the rain
  - stimulates growth
  - uptake involves ammonium
* accelerates composting.
* accumulates in soil during the process of soil formation.
* acidifies the soil.
* acts as a catalyst
  - suppressant to fungal growth
* alloying additions increase the strength of the austenitic steels.
* binds to the zeolite, while oxygen passes through.
* builds up in a variety of forms on the catalyst surface
  - winter but is severely depleted in summer
* can be side-dressed when cultivating or hoeing or applied and irrigationd into the soil.
  - many sources
  - off as the first fraction, oxygen is second
* concentrates in leaves.
* containing fertilizers and fossil fuels release pollutants that increase soil acidity
  - plant compounds include amino acids, the building blocks of all proteins
* controls on fine root substrate quality in temperate forest ecosystems.
* demanding species, especially grasses begin to dominate.
* dioxides mostly result from burning fuels in utilities, industries, and motor vehicles.
* dissolves in blood.
* emits a pale orange light.
* enters ecosystems primarily through the actions of nitrogen fixing bacteria.
* enters the aquarium in the form of protein in food as ammonia from fish waste
  - living world from the atmosphere via nitrogen-fixing bacteria
  - plant largely through the roots
  - soil through atmospheric fixation
* evaporates more rapidly than oxygen from the liquid air.
* favors leaf growth and imparts a deep green color to plant foliage.
* fixing bacteria are essential for soil fertility
  - nature's main method of changing nitrogen to plant available forms
  - either live symbiotically with plants, or live freely in the soil
  - play an important role in the soils of earth
  - eubacteria has a role in the nitrogen fixation process
  - plant species are among the most invasive species worldwide
  - plants are key constituents in many natural ecosystems in the world
  - trees provide a way of extracting minerals from the soil with a deep taproot
* flows inside the tube while helium flows outside the tube
  - on poultry farms
* flushing is referred to under controlled atmosphere stores.
* forms a molecule when a triple bond joins two atoms of nitrogen
  - about four-fifths of the atmosphere
  - trivalent bonds in most compounds
  - two series of especially important chemical compounds
* glows with colours that range from a deep red through blue and ultraviolet.
* helps improve color and density of the grass
  - in full sun to part shade
  - plants make lots of leaves and is important in helping plants get their green color
  - prevent reaction between the gas and minerals in the rock
  - promote green color and a thick, dense lawn
* increases in a non-nodulating soybean grown with nodulating genotypes
  - seed yield
  - located in air
* isotope ratios of natural and anthropogenic nitrate in the subsurface.
* leaches out of the soil easily, and levels can fluctuate through the growing season.
* limits productivity in most ecosystems, including agroecosystems.
* moves easily through the soil and can be applied before or after planting
  - in the soil water
  - to active young buds, shoots and leaves and slower to older leaves
  - through subsurface flow, and it is removed by trees which are adjacent to a stream
* moves through the food chain as organisms eat plants and are themselves eaten
  - soil fast than phosphorous
* prefers to form three bonds and have one lone pair of electrons.
* promotes leafy growth and is commonly associated with making the grass green.
* reducing bacteria generally exist in any natural water containing elevated nitrate.
* residues from brassica crops.
* returns to the atmosphere primarily through biomass combustion and denitrification.
* slows down nerve conduction.
* starts off the process of reducing the carbon in the following layers.
* stimulates growth before the plant's development of nitrogen-fixing root nodules
  - humus-consuming bacteria
  - microbes to devour carbon
  - more grass production
* stimulates new growth and keeps leaves green
  - the new growth is highly susceptible to fire blight infection
* tends to be inert to most spray material except materials like titanium
  - form covalent compounds
  - promote vegetative growth relatively more than reproductive growth
* transformations along a eutrophic gradient in the northern Everglades, Florida.
* use efficiency in horticultural crops.
* volatilizes as ammonia from hog waste, lagoons and crop sprays.
* wastes and electrolytes continue to be excreted, but at abnormally low rates.
