to what's already been said except do base your use of
lime on evidence from pH tests and don't overdo it - especially
hydrated lime, an excess of Calcium can cause problems like
rendering
some minor nutrients unavailable. This is a particular problem
with
brassicas like caulis. Dolomite (Magnesian) limestone which is a
variable mix of Calcium and Magnesium carbonates etc is useful
where
you want to get the pH up without overdoing the Calcium.

Doesn't too much lime in the soil give potatoes scab?
Yep. If one limes at all, it should in theory be in a planned
rotation so the potatoes go into the place which is due to be limed
next, while the cabbages go into the bit which has just been limed.
