Once it hits the soil it is chemically changed, and harmless to plants.

One it hits the soil it gets bound to soil particles, and pretty mich
inaccessible to plants. It is broken down over time by bacteria, but the
half-life varies with soil-type. (A range of 1 to 174 days can be found
on the web.)

What is 'bound' if not a chemical reaction?

It's what chickens get.

I always called it 'trussed'...
