The Dolomite Problem | Discover Magazine

The Dolomite Mountains, Italy's Alpi Dolomitiche, however, are a special case: the rock in them was originally simple calcium carbonate made from dead corals and seashells on the seafloor. Only later was it transformed into dolomite through the orderly addition of magnesium--and through the action, McKenzie suspects, of sulfate-reducing bacteria.

The crystalline, porous structure of Dolomite also provides aeration to the soil, stimulating nitrogen production and absorption. This enrichment helps with both magnesium and potassium deficient plants, allowing them to flourish. Additionally this boost can last between 2-4 months, whereas regular Limestone would only last between 1-2 months.
