Oyster Shell is an all natural and high quality source of the essential plant nutrient calcium. Ancient oyster shells are carefully harvested and then ground into small, medium and coarse particles. These irregular shapes provide a sustained release of this valuable nutrient and help prevent deficiencies that can diminish plant development. Oyster Shell also aids in improving structure of soils and building optimum tilth.
