In America this seems to be a generic term with variable meaning so lets
divide it up into :: High calcium lime which is Calcium Carbonate - this is
mined and crushed from the type of rock where you find underground Limestone
caves
:: Dolomitic Lime (or dolomite) which is a mixture of Calcium
Carbonate and Magnesium Carbonate
> Calcium
Refers to the metallic or elemental form - look in a dictionary or
scientific text
> Prilled calcium
Used to describe a re granulated form of high calcium lime - its treated
this way to make it easier to spread .
> Gypsum,
Calcium Sulfate - often refered to as 'clay breaker' in the store or garden
shop - mined from soft underground deposits in dry inland areas where old
lakebeds were - or obtained as a by product of concentrated phosphate
fertiliser manufacture - this form will likely have some heavy metal
contamination concentrated from the original source material (cadmium,
lead,) . Gypsum is the white stuff they make wallboard for your house. When
we use high rates of gypsum we are supplying a massive overdose of sulfate
sulfur .
