Anyone putting tractor exhaust into the ground?

How is it working? Saving on fertilizers?
Something I don't understand is their coolers, couldn't one just mix the exhaust air with cool air right at the tractor exhaust sucking the air to deliver it to the air tank fan? Could be quite a cheap set up that way.

I would try one withouy coolers, may help warm the soil up -lol.

The two guys I know who have them.
1st is now putting down liquid fert with his seed plus the exhaust. The second I am not sure what happened. I think they missed a few good years of crops.

Maybe it was too good to be true, at the N savings they were claiming it would have paid to mount another 535 hp motor on the drill just to make N. Well perhaps there could be something to this some day, the air is made up of mostly N.
Someone may just figure out how to get it plant availlable in the soil economically,
