abono nitrogenado | nitrogen fertiliser |
abono nitrogenado con magnesio | magnesium ammonium nitrate |
bacteria fijadora del nitrógeno | nitrogen-fixing bacteria |
bacteria fijadora del nitrógeno | azotobacter |
ciclo del nitrógeno | nitrogen cycle The complex set of processes by which crops acquire the large amount of nitrogen they need to make proteins, nucleic acids and other biochemicals of which they are composed, and how the nitrogen returns to the atmosphere |
compuesto de nitrógeno | nitrogen compound |
compuesto de nitrógeno | compound of nitrogen |
contaminación nitrogenada | nitrogenous pollution |
dióxido de nitrógeno | nitrogen dioxide A reddish-brown gas; it exists in varying degrees of concentration in equilibrium with other nitrogen oxides; used to produce nitric acid, NO2 |
fertilizante nitrogenado | nitrogenous fertiliser |
fertilizante nitrogenado | nitrogenous fertiliser Fertilizer materials, natural or synthesized, containing nitrogen available for fixation by vegetation, such as potassium nitrate or ammonium nitrate |
fijación biológica del nitrógeno | biological nitrogen fixation |
fijación de nitrogeno | nitrogen fixation |
fijación de nitrogeno | nitrogen fixation Assimilation of atmospheric nitrogen by a variety of microorganisms which live freely in soil. Once the nitrogen has been captured by one of the microorganisms, there are many different routes by which it is handled. Some is retained in the soil as decomposing plant matter, waiting to be released and taken up by new crops as a nitrate. That nitrate is produced by nitrifying bacteria living in the soil that thrive on ammonia, which is produced by decaying plant and animal material. In processing nitrogen the nitrifying bacteria produce nitrate that can be absorbed by the roots of plants |
fijación del nitrógeno | nitrogen fixing |
fijación del nitrógeno | nitrogen fixation |
hemióxido de nitrógeno | E 942 |
monóxido de nitrógeno | nitrogen monoxide |
monóxido de nitrógeno | nitrogen monoxide A colourless gas, soluble in water, ethanol and ether. It is formed in many reactions involving the reduction of nitric acid, but more convenient reactions for the preparation of reasonably pure NO are reactions of sodium nitrite, sulphuric acid, etc. |
nitrógeno orgánico | organic nitrogen |
nitrógeno orgánico | organic nitrogen Essential nutrient of the food supply of plants and the diets of animals. Animals obtain it in nitrogen-containing compounds, particularly aminoacids. Although the atmosphere is nearly 80% gaseous nitrogen, very few organisms have the ability to use it in this form. The higher plants normally obtain it from the soil after microorganisms have converted the nitrogen into ammonia or nitrates, which they can then absorb. This conversion of nitrogen, known as nitrogen fixation, is essential for the formation of amino acids which, in turn, are the building blocks of proteins |
nitrógeno oxidado total | total oxidized nitrogen |
nitrógeno total | total nitrogen |
oxidos de nitrógeno | nitrogen oxides |
oxidos de nitrógeno | nitrogen oxides Oxides formed and released in all common types of combustion; they are formed by the oxidation of atmospheric nitrogen at high temperatures. Introduced into the atmosphere from car exhausts, furnace stacks, incinerators, power stations and similar sources, the oxides include nitrous oxide, nitric oxide, nitrogen dioxide, nitrogen pentoxide and nitric acid. The oxides of nitrogen undergo many reactions in the atmosphere to form photochemical smog |
sustancia nitrogenada | nitrogen substance |
óxido de nitrógeno | oxide of nitrogen |
óxido de nitrógeno | nitrogen oxide |
óxido de nitrógeno | nitrogen oxide A colorless gas that, at room temperature, reacts with oxygen to form nitrogen dioxide; may be used to form other compounds, NOx |
