New Earth Cal-Abunga: Aragonite – CA 33%
$5.99 – $12.99
Made of fine ground mollusk shells, this source of calcium gives strength to cell walls and encourages reproduction of new growth along with preventing and correcting blossom-end rot.
Aragonite is derived from the sea and is exceptionally high in calcium but low in magnesium. Many soils have had dolomite lime added for years, tying up magnesium and other nutrients in the soil. Gypsum and aragonite should be used to offset a high mag content soil.
