Oyster Shell Flour (5 lb Box)
Improves Soil Tilth and Builds Healthy Root Systems
Down To Earth’s 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.
- Natural, organic source of calcium is used to correct Ca deficiencies and raise pH in acidic soils.
- Contains 35% calcium
- Variable particle size provides both immediate and long-term fertilization.
- Use at 2.5-5 lbs per 100 square feet or 2.5-5 lbs per 100 square feet, depending on soil analysis and crop. Repeated applications may be needed to fully adjust pH and Ca levels. Spread 1 lb per 1″ of trunk diameter around the base outwards to the drip line, mix into soil surface and water in well.
