Down To Earth Oyster Shell Fertilizer

Oyster Shell is an all natural and high quality source of essential plant nutrient Calcium. Ancient oysters shells are carefully harvested and then ground into small, medium and course 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.
