I got some lime from my father-in-law. It have been sitting surrounded by a field for almost 15 years. Would it hold lost its ability to neutralize sharp? Maybe from acid rainfall?
Answers:    I think this requires a short time more information for instance has it be openly piled within this field for that long or be it shelter protected like beside plastic?

If it was freely sitting in this paddock I doubt it is worth saving. At lowest some of it must have turned to concrete by this time and it have to have be infected by unwanted bacteria and possibily some fungi things. I would advise not using this stuff.

If it was stored underneath a plastic shelter and the plastic has not be compromised in any trend and no critters have be using it as a warm place to nest after it maybe ok. I would still be terrifically cautious roughly using this material. Without knowing the exact circumstances of the storage this is the best I can proposition.
