Healthy soil and sustainable growing

[Mark Nagel <activism98201@verizon.net>]

I've been planning on relocating and discovered that the general area that 
I'm interested in has lime deposits.  Being that this is a northern lattitude 
I'm figuring that having access to lime would be good.

I've run across some information, but it's based on construction rather than 
agricultural use.  It talks about limestone being in marble and about there 
being various levels of carbonate of magnesia (upwards of 20%).

In lime, what is and what isn't viable for agricultural use?  And, are there 
any concerns about carbonate of magnesia?
