nitrogen
Primary plant macronutrient and a major component of proteins and nucleic acids Inert atmospheric dinitrogen gas must be converted to soluble forms in the soil A major way it is converted is through the action of nitrogen-fixing bacteria symbiotically associated with the roots of leguminous plants Common soluble soil forms are the ammonium monovalent cation and the nitrate monovalent anion
A colorless, odorless gas used in a variety of fabrication processes - etching, deposition and anneal
A nutrient present in ammonia, nitrate or nitrite or elemental form in water due possibly to nonpoint source pollution or improperly operating wastewater treatment plants
Nitrogen is a gaseous element that occurs in air (78% of air volume) It is an essential component of proteins and nucleic acids in living organisms
Nitrogen is a colourless element that has no smell and is usually found as a gas. It forms about 78% of the earth's atmosphere, and is found in all living things. a gas that has no colour or smell, and that forms most of the Earth's air. It is a chemical element : symbol N (nitrogène, from nitre ( NITIC ACID) + -gène ). Gaseous chemical element, chemical symbol N, atomic number
A chemical element (symbol N) with an atomic number of 7 and atomic weight of 14.0067
One of the major nutrients required for the growth of aquatic plants, usually present in water as organic nitrogen or as inorganic ammonia and nitrate High concentrations of nitrogen can cause overabundant aquatic plant and algal growth
It is chemically very inert in the free state, and as such is incapable of supporting life (hence the name azote still used by French chemists); but it forms many important compounds, as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable
One of the essential elements of plant nutrition, identified by the chemical symbol N It promotes above-ground growth, particularly in green tissue in stems and leaves
An element essential to the growth and development of plants; occurs in manure and chemical fertilizer and, in excess, can cause waters to become polluted by promoting excessive growth of algae and other aquatic plants
One of the elements essential for the growth of organisms Nitrogen is most abundant in the form of N2 and comprises 80% of atmospheric constituents
vital to plants for foliage color and density and for root growth This is the primary nutrient that needs to be replaced
A gaseous element, atomic number 7, relative atomic mass 14 0067, symbol N It is the principal constituent of air (78% by volume)
The 14th of the 107 elements Nitrogen is important for plant growth and is found in many commercial fertilizers It also is found in the environment in different forms (sometimes as a gas, sometimes as a compound with Oxygen or Hydrogen), from both natural and man-made sources Because of this, it is often washed through a watershed into a stream or river If there is too much Nitrogen in the water, it is a pollutant
in the form of ammonia, nitrate and urea
A gas that causes algae to bloom and disables chlorine It is brought into the water each time it rains Maintaining proper chlorine levels will prevent nitrogen from becoming a problem Superchlorination will remove nitrogen and its related compounds
Gas Chemical symbol N Atomic weight - 14 0 Dissolved nitrogen gas is the primary cause of supersaturation as it is the gas in most abundance in the water In stabilised waters the percentages of dissolved gas in the water are the same as those in air Nitrogen forms a significant part of the waste from fish farms This is primarily in the form of ammonia and nitrate The amount of nitrogen added to a fish farming system can be calculated from the protein level of the feed Boiling point -195 8oC, melting point -209 9oC 1 m3 nitrogen gas = 1 2506kg For every gram of protein added to the system, 6 25g of nitrogen will be produced in one form or another This includes the fishes body tissues that contain nitrogen locked up in compounds in the cells As a rule of thumb, approximately 90% of the fishes nitrogen excretion is in the form of ammonia
Nitrogen is the most abundant element in our atmosphere It is a vital element that is essential to living ecosystems Nitrogen is a primary nutrient for all green plants
An element occurring in manure and chemical fertilizer that is essential to the growth and development of plants, but which, in excess, can cause water to become polluted and threaten aquatic animals
