>The nitric oxide so formed then reacts with more oxygen to form nitrogen dioxide. Nitrogen dioxide so formed, gets washed down by rain and forms nitrates and nitrites in the soil. Plants absorb these of nitrates and nitrites from the soil and convert them into plant proteins. A..

Nitrogen is an important structural component of many necessary compounds, particularly proteins. Atmosphere is the reservoir of free gaseous nitrogen and nitrogen compounds are found in bodies of organisms and in the soil. Living organisms cannot pickup elemental gase..

: Rhizobium, a nitrogen fixing bacteria present in the roots of leguminous plants, fixes atmospheric nitrogen to the soil. Azotobacter and Clostridium are other free-living nitrogen fixing bacteria. Physical fixation When nitrogen..

Atmospheric nitrogen can be fixed into usable form by natural processes. Two ways of natural fixation of free nitrogen ar..

Conversion of nitrogen into compounds is essential by combining with carbon, hydrogen and oxygen before it can be absorbed by the plants. This is known as nitrogen fixation. The micro-organisms which can fix atmospheric nitrogen can be classified into two mai..

The process is the transformation of gaseous nitrogen into nitrates by living organisms. Biological nitrogen fixation occurs by: a) Symbiotic nitrogen fixation, which is brought about by certain bacteria such as: i) Rhizobium species in the root nodules of legumes (pe..

In this case, there will be a reversal of phase due to reflection. Let the incident wave be represented by the equation. The reflected wave will have the same magnitude of the amplitude, velocity and wavelength. Due to reversal of phase (i.e., a crest returning as a trough or vice versa) the sign o..

>When nitrogen is heated with calcium carbide at 800 o C to 1000 o C, nitrolim an important fertilizer is formed. Nitrogen is used in high temperature thermometers, as a refrigerant and in electric bulbs. Nitrogen cycle charts the circulation of nitrogen comp..
