I try to write about lime, how and why it is used here in the land of Father Christmas.
Finlands is a sour country. Forestlands, groundwater, fields, swamps, everything is more or less acid soil and water. For example groundwater has pH 5 on average. Lakes have higher, pH average is between 6-7. Peak from swamps pH is 3-4, forests pH is around 3,6-4,3 fields are normally under 6 (if not spreaded lime). So if you want to cultivate something, you are better to lime the soil before you do anything else... lol. Yep, I have learned The Lesson.
In fresh pigmanure, or chickenmanure, burnt lime [Ca(OH)2] is used to kill salmonellabacteria, if manure is not composted. There must be used burnt lime, so much that pH rises up till 10 and salmonella dies. Quite quick pH comes down to around 7 and manure can be used in fields. If the manure is composted, then it is in piles, gets hot when it is "burning" and salmonella dies because of the heat. Pile is covered with burnt lime, so the salmonella won't infect birds or anything else who touches the manure. Burnt lime is not the same as "normal" lime (CaO) what is used in gardening. Burnt lime takes pH as up as much you put it, but "normal" gardenlime does not rise pH over 7. "Normal" lime also includes some magnesium (Mg).
