denitrifying

Modern synthetic fertilizer is made from the air and returns to the air via denitrifying bacteria, yet few would call it a renewable resource.

The more rapidly water gets into circulation, the more action of denitrifying bacteria in breaking down nitrate beds to increase the atmospheric nitrogen supply and the spread of plants to produce oxygen will be accelerated.

If the pile is too wet the air will be forced out, leading to an increased population of anaerobic, denitrifying bacteria which lose nitrogen by releasing it into the air.

There is no reason, however, to suppose that this is so, and several of the denitrifying organisms have been identified.

Manures and the principles of manuring Charles Morton Aikman

In the rotting of our farmyard manure it is possible that the denitrifying organisms may be more active than we have hitherto suspected, and that a considerable loss of nitrogen may in this way be effected.

Changes in denitrifying bacteria: These bacteria convert anthropogenic nitrogen (via fertilizer runoff into rivers, etc., etc.) to molecular nitrogen which then is reincorporated into the atmosphere.

However, these communities, especially it seems in estuaries, have become nitrogen fixing, rather than denitrifying, effectively becoming a source of nitrogen, rather than a sink, with possible ramifications in ocean acidification or the production of nitrous oxide, a greenhouse gas.
