N uptake

Another thread made me wander...

Knowing that microbes store N, what forms of N are they capable of storing? Does it have to be broken down N that comes from items such as grass clippings, or manure, OR can they also store already available N such as what is found in synthetic ferts? In Kirils chart I would assume my "already available N" would be the NH3-

On his chart the N is taken up or broken back down and released back into the atmosphere?

What technical form of N is found in synthetic ferts and Urea?

Both forms (ammonium & nitrate).

Also know that the simple N like Ammonium and Nitrate inside microbes is used to build complex molecules AKA proteins... like those found in DNA... This means that it is not necessarily stored in plant available form once it has entered the biomass. When the microbe dies it needs to be broken down to be plant available...

Or when the microbe is eaten by something else, for instance protozoa eat bacteria, certain nematodes like to eat bacteria, just like with worms the poop is great fertilizer in a plant available form

Its little tiny poop but the numbers can be pretty staggering, On some testing we had done last year there were over 12,000 of ONE TYPE per ml of soil

It's not my chart, just one I link to that I have seen many times throughout the years.
Ammonium should also have a very small arrow to plant uptake.
