@Brisel I'd rather you didn't as I seem to remember they were sharp and hurt and caused puncture wounds in almost anything..
The decision we have to make, or should I say, have the option to make, is to use Ca or Mg lime. I spent 12 years on the Herts Cambs border on some chalky land, over the 12 years I was there we did not spread 1 tonne of lime on the 5000+ac so the ability to influence it was nil with lime.
In Scotland where the soils are mainly naturally acidic then by this nature we have the ability where we can to influence the Ca:Mg ratio in lime applications perhaps more frequently than you (???)
Personally I like to use gypsum in the potato rotation, not to influence the pH but to bring up the Ca and S levels.
For many years the "aye been" approach to liming is flat rate Mg lime and some of the Mg levels are off the scale in our area.
Out of interest what are your average pH levels?
For me I see Calcium as the "trucker" for other elements during the growing season
