Where can organic nitrogen be found in the nitrogen Cycle?
Starting with ammonium, NH4, which nitrifiying bacteria transform into nitrate (NO3-)and nitrite (NO2-). However, of these compounds, only nitrate is assimilated by plants, making it organic. If not assimilated by plants, denitrifying bacteria take the nitrate and convert it back to atmospheric nitrogen (N2).
What converts organic nitrogen into atmospheric nitrogen?
the slaves have to put it in there stew and then they eat it
If you have isolated a bacterium that grows in a medium containing an organic substrate and nitrate in the absence of oxygen The nitrate is reduced to nitrogen gas This bacterium is?
Using anaerobic respiration
What form must nitrogen take before plants and animals can use it?
through roots from the soil
Why do farmers put nitrogen on their plants?
What organic molecules is nitrogen found in
How are some of the nitrate ions made naturally?
Nitrate (NO3-) and nitrite (NO2-) are naturally occurring inorganic ions that are part of the nitrogen cycle. Microbial action in soil or water decomposes wastes containing organic nitrogen into ammonia, which is then oxidized to nitrite and nitrate.

What is nitrogen mineralization?
Nitrogen Mineralization is the process in which organic forms of nitrogen {proteins in dead plant material} are converted by microbes to in-organic forms of nitrogen {ammonium & nitrate}
Nitrate reduction test what does the presence of gas indicate?
if you look up the term Denitrification The formation of gaseous nitrogen and/or oxides of nitrogen from nitrate or nitrite by certain bacteria during ANAEROBIC RESPIRATION. Denitrification only occurs in ANAEROBIC or MICROAEROPHILIC conditions when there is sufficient organic carbon to support reaction. Denitrification may be used as a treatment technology to remove nitrogen oxides from liquid waste streams.

What is anoxic decomposition?
Anoxic decomposition is a biological process in which a certain group of microorganisms use chemically combined oxygen, such as that found in nitrite and nitrate. The organic matter they consume supports their life functions and nitrogen gas, carbon dioxide, stable solids and more organisms are produced in the process.

How do you calculate total nitrogen in organic manure?
Organic manure has liquid fraction and solid fraction bot contains an amout of nitrogen. So we cannot simply add them together
What are inorganic nitrogen compounds?
Any nitrogen compound that does not contain carbon is an inorganic nitrogen compound. Common examples are the oxides with formula NO, NO2, and N2O5; nitric acid and nitrate salts (unless their cations are organic); ammonia and ammonium salts (unless their anions are organic); and metal nitrides.
Is N2O5 an organic compound?
Organic Chemistry is by definition "The Chemistry of compounds of Carbon". Note octane, and lipid chains; carbon may polymerize. Considering Nitrogen, just add it to the above to obtain Biochemistry!
What is relationship nitrate and ammonium?
Plants cannot use organic nitrogen directly. "Microorganisms in the soil convert the nitrogen locked up in crop residues, human and animal wastes or compost to ammonium (NH4). A specific group of microorganisms convert ammonium to nitrate (NO3)" 58. Since nitrate is water-soluble, excess nitrate not used by plants can leach through the soil and into the groundwater.
