My son works in a nursery and they had several bags of Lime and One bag of Ammonia/nitrate . They said it was no good to dispose of it . I told my son to bring it home, that I couldn't imagine lime going bad or the Soda/nitrate . What about you guys that are in the know . Question . Does it go bad, it might lose its full strength and then it might not . What do you guys think or know ?
