It's called crop rotation; where a nitrogen fixing plant is the next crop in a field so that the amount of fertilizer can be reduced. For example a farmer plants wheat and then after harvesting and plowing the remainder under the farmer plants peanuts. The wheat exhausts the soil of nitrogen that can be replaced with expensive and polluting fertilizer; or the farmer can plant a crop of peanuts ...

In general, the nitrogen cycle has five steps: 1.) Nitrogen fixation (N2 to NH3/ NH4+ or NO3-) 2.) Nitrification (NH3 to NO3-) 3.) Assimilation (Incorporation of NH3 and NO3- into biological tissues) 4.) Ammonification (organic nitrogen compounds to NH3) 5.) Denitrification (NO3- to N2) For detailed information, visit this link http://www.fondriest.com/tech_notes/nitr…...

Salters Nitrogen Cycle

Started 1 week, 5 days ago (2010-03-09 14:36:00) by DakotaSB91

Hi, First of all, this is the first time starting a thread so if i have posted in wrong section or anything please let me know! My question is on the denitirification process brought about by bacteria in the soil during the nitrogen cycle. I have been asked to write a half equation for the conversion of NO into N2O. I have been told it uses electons, water molecules and H+ ions...

The sun gives plants energy and allows them to grow. Plants are eaten by animals. At the end of their lives, plants and animals both decompose, which puts bacteria in the soil which are needed for the cycle. Also don't forget legumes, which fix nitrogen in their roots and put it in the soil - they use the sun's energy to grow too. Without energy from the sun, none of this would happen.

Nitrogen Cycle....HELP!?

Started 1 month ago (2010-02-16 13:54:00) by ḿằḵἔ ḿἔ (Fish N00b) ͼ(^ᴥ^)ͽ

I have a couple questions about the nitrogen cycle and what I need to do. - How long is it? - How much do test kits cost? - Do I have to do new nitrogen cycles every time I get a new fish? - How frequently do I have to do nitrogen cycles? I'm sorry, my last experience with fish was TERRIBLE because I had so many things to do (school, etc.) and I'm buying my betta in the ...

Cheating the nitrogen cycle...?

Started 1 month, 1 week ago (2010-02-07 21:29:00) by Michael

Is it possible to jumpstart the nitrogen cycle by switching the water from an established tank to a brand new tank? I still wouldn't move over all my fish right away except maybe my betta, but this should work right? Would the fish be ready to move into the new tank already or should I still wait? If so, for how long?

hi , im new here :) weve started up our second tank about 10 days ago, (300l) and we bought 30kg of LR (cured from a guy on ebay who was downsizing) along with 25kg of live sand and sump sand and some cheato. anyway my tests i had were pants, (ive never had an NH4 test) ive gone and purchased salifert tests just now and tested my tank. i think from my pants test that ive had a NO2 spike ...
