Down To Earth™ Oyster Shell 1 LB
Down To Earth™ 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. DTE™ Oyster Shell also aids in improving structure of soils and building optimum tilth.
Help prevent calcium deficiencies that can diminish plant development.
Oyster shell provides a long-lasting, steady release of nutrients to help regulate pH levels, improve fertilizer uptake, promote healthy cellular structure and enhance soil tilth.
Oyster shell is also helpful in creating more active habitats for soil microbes in compost piles and worm bins.
