the smell that cleans your house and could fertilize half the planet's dinner

means A pungent, colorless gas made of nitrogen and hydrogen (NH₃), dissolved in water to make a sharp-smelling cleaner and used industrially to make fertilizers and explosives.

from The name traces back to the Temple of Ammon (Amun) in ancient Egypt, near which a salt called 'sal ammoniac' — ammonium chloride — was gathered, reputedly from the dung and droppings of animals around the shrine. The Latin 'sal ammoniacus' meant 'salt of Ammon,' and when chemists later isolated the sharp gas from such salts, they named it ammonia, carrying the desert god's name into the cleaning cupboard.
