Something is needed to immediately react with that. Sulfur is a more long term solution that does get applied in conjunction with citric acid drenches. I have my soil sent to either A & L West or Brookside.
Interesting. I'm guessing then that this is related to the CEC levels? Both citric acid and sulfur are then catalyctic agents for the release of said cations, but sulfur specifically will create a prolonged increase in the soil's CEC? Just want to clarify.
