Nice, isn´t it?
Another kind of biological fixation:
Piss on a heap of straw, mixed with CaCO3. Have a little patience.
It has to be a loose heap, so that air is able to enter the heap...
Ca(NO3)2 is very slowly generated, and can be used to make KNO3, for example.
Reduce the NO3- with Fe2+, for instance, and you get NH3.

What you are describing is the classic means of making nitrates from the oxidation of NH3 (and urea?) by bacteria, the actually 'fixation'
of nitrogen from the air takes place in plants (legumes) and by lightning bolts, fires, and other slow processes. The bacteria strip off the hydrogen
and replace them with oxygen, thus using the ammonia as food. Another step to making the saltpeter (salt of rock) is to take the calcium nitrate
obtained and filter it through wood ashes (potash, or potassium carbonate) and you obtain calcium carbonate again, and potassium nitrate. Has anyone
actually tried this or have all just been reading about it?
The raw materials
should be easy to obtain.

Why would anyone want to get rid of the Ca nitate, its got the most beutiful color while burning, ive ever seen.

Orange/pinkish...
I like it too...
But very hygroscopic :-S
