Lime (calcium carbonate) in this case is a mineral with a PH of around 8.4. Lime juice is acid yes. Bases are alkaline (PH above 7.0) and acids are acid (PH below 7.0).

Herbus Reviewed by Herbus on . Lime and Ammonium Nitrate a No No!?? I don't use dolomite lime but I do have ammonium nitrate in my ferts. I read somewhere that the ammonium nitrate will interact with lime and produce toxic ammonia gases also making the nitrate unavailable to the plant. I'm raising this as a possible problem for the pro's to confirm as I could imagine a lot of soil growers would use these ingredients. Zandor do you know anything about this? Rating: 5
