Does anybody know what happens to the Hydrogen form the Ammonia (3 times as much as Nitrogen).
Mailwatch chemistry time!
A bit of speculation here. Put simply:
Ammonia (NH3) is oxidised to nitrogen dioxide (NO2) which dissolves in water to produce nitrous (HNO2) and nitric acid (HNO3) which are neutralised in the soil going on to produce various nitrite (iii) and nitrate (v) salts.
The hydrogen in ammonia is converted to water (H2O) and hydrogen ions (H+) the latter of which are responsible for acidity (acids being molecules that release H+ ions into solution) these are usually also eventually neutralised by bases in the soil to form more water and a variety of salts.
The um.. "shitening" - to coin a phrase - process described seems to imply they use electrolysis to oxidise (nick electrons off) the nitrogen atom into ammonia to make molecular nitrogen (N2). This would also produce three times the molar ratio of molecular hydrogen (H2) gas for one mole of N2. It is a way of getting rid of ammonia (Indeed, the Haber process which produces ammonia from nitrogen and hydrogen is actually reversible and some of the ammonia formed does just this and decomposes back to its constituent elements given the right conditions.)
but it sounds very energy consuming, and would be an utter pain in the arse to do in practice. Hydrogen (and any other nearby poo gases) is also very flammable so there's that headache to deal with too. They also say that the nitrogen is absorbed back in the shite, but elemental nitrogen is practically inert, it needs to be a nitrate or an ammonia derivative to be able to be used as a nutrient. Most of it would just drift back into the air.
You could say it would be a shit storm.
I'll get me lab coat!
