Okay, this is my understanding:
Leachable nitrogen and readily available nitrogen equals nitrate.
The nitrate is taken up by bacteria. Without the protozoa in the
food web, the N can stay sequestered (except when the B die) and not
be out there available for the plants.
The protozoa eat the bacteria and release the nitrate/make available
again in the form of ammonium nitrogen.
Question: Do bacteria poop out nitrogen? In what form??
(Never saw anybody ask that question before on the list...)
