Ground Oyster Shell, also known as Aragonite, is an ocean based source of calcium that is low in magnesium.  Aragonite or oyster shell flour contains a combined total of 97% calcium carbonate and calcium silicate.  This finely ground oyster shell has a consistency like fine beach-sand making it an excellent addition to clay soils.  Aragonite can also be added to potting mixes, planting mixes and soil-block mixes. 

Oyster shell meal supplies a minimum of 33% - 40% immediately available calcium and will slowly release the remaining calcium over the years ahead making permanent improvement to soils where it is applied.
