My link is how ammonia is formed which is a component of ammonium nitrate, you cant get AN from haber bosch, it requires a seperate acid reaction, urea is formed from ammonia and is the more common form of fertilizer. Ammonium nitrate is a pain to find nowadays. I don't know where your education is from but the only nitrogen source that damages soil microbes is anhydrous ammonia due to its gaseous form. Nothing else damages them, putting wood chips in the soil can be more be considerably more harmful than applying 10-10-10. Those microbes I applied were still alive due to the fact that they were refrigerated until they were applied. There's just some claims that chemistry and biology don't back up.
