They don't.
I've stuck washers, steel wool and nails under my gravel for about a decade
now. No, they can't use rust, but under anaerobic conditions it's
reduced and usable by the plants. Snails and shrimp are unaffected.
If I pull say, Crypt roos out, they're white for 2-3" then all rusty
brown just like in the Dupla book field pictures.
I've seen roots grow around a washer like they were sucking the
juice out ot it.
