So what percentage of air is Potassium ?K is a cation, hence it binds clay colloids, however it doesn't flocculate soil like ca, it makes cement, we have acres of the stuff.
Cl sterilises soil life, I forget the numbers but it's only a few hundred pounds per acre in one go to deliver enough cl to kill all life.
Crops draw k from the air, if you don't remove stover the levels should rise in time supposing it isn't leaching too fast to keep up.
Or so I'm led to believe
