My father-in-law claims that since plants need nitrogen to produce proteins, and since ammonia is NH3, that Ammonia should be fine for the plants, since it's just nitrogen and water and hydrogen, according to him. We were cleaning a rusty chain and a bunch of spilled into our garden. I'm talking about household ammonia.
Is that true?
I'm thoroughly convinced he is an utter idiot but then again he could be right since he does say he minored in Chemistry in his college days.
