Description

Oyster Shell flour is an all natural source of high quality Calcium that is ground into varying sizes to ensure an immediate and sustained release of this valuable nutrient. Calcium promotes strong root development, improves nutrient uptake and boosts plant immunity. Oyster Shell builds optimum tilth by improving the texture, aeration and water penetration of soils.

  • Natural, organic source of calcium is used to correct Ca deficiencies and raise pH in acidic soils.
  • Contains 36% calcium.
  • Variable particle size provides both immediate and long-term fertilization.
  • Use at 4-5 lb/20 row feet for flowers and vegetables or 1 lb/tree, 2-10 lb/100 sq ft or 500-4,000 lb/acre, depending on soil analysis and crop. Repeated applications may be needed to fully adjust pH and Ca levels. In acidic soils, add 1-3 lb/hole when planting trees.
